New description: [New technical field] This creation department (4) - a kind of logic connection control electric conversion device, into the characteristic single-stage logic connection control power conversion device. [Prior Art] Power supply is a source of power for electronic products or equipment. In order to comply with the trend of product miniaturization, switching power converters have gradually replaced the traditional linear power conversion benefits. Usually the side-form "conversion H requires red at a higher switching frequency to effectively reduce the volume of the (10) element and the capacitor, so that the unit resolution of the power converter is improved. However, when the switching frequency is increased, the number of switching of the power element is relatively increased, and the cost is that the electromagnetic interference of the switching loss fish becomes large. In addition, in recent years, the manufacturing of the rotating component has progressed, and the rectification and the number of the power-related components have made the electrical conversion power supply material a considerable constraint. In order to improve the power supply quality of power supply equipment and improve the power supply's remarks, many countries have begun to set regulations and standards related to power quality, and their electronic technology will be the key to the adoption of electronic products. In line with the regulatory requirements of the 35-wave standard, the power factor correction technique has become one of the current key researches. Its main purpose is to improve the utilization of effective power, reduce the input surge current, and suppress the harmonic components of the input current. However, in one of the conventional AC/DC converters, a two-stage power converter is used. Please refer to the first (Α) diagram, which is the power factor correction converter in the front stage. After 1〇1, a step-down DC/DC converter 121 with isolated output is added. The entire power converter system requires two completely independent control loops, 1 and 12, to adjust the stable DC output voltage of the latter stage, respond quickly to the M312840's load ripple, and allow the input current to follow the input voltage waveform. The input requires high power requirements. Since the design of the power converter is subjected to two power conversions, the overall efficiency is seriously degraded and the control circuit is complicated and the cost is increased. Therefore, in order to improve the various shortcomings of the conventional two-stage power converter, another conventional single-stage power conversion H has been developed. Please refer to the -(8)_ display to integrate the God-corrected circuit to DC/ The DC converter is used to form a power factor correction and DC/DC converter. Therefore, the power factor correction circuit, isolation, and fast load 22 dynamic response are all performed in a single architecture. Furthermore, due to the power factor correction circuit and DC The /DC converter 2〇 shares the power switch with the controller %, so the cost and control complexity can be reduced. Although, in the above-described conventional single-stage power converter, the effect of (4) can be obtained according to different circuit topologies', for example, a single-stage power conversion composed of an integrated boost-type conversion-return-to-return conversion ride, Has a good power with the correction effect; and the age of the Wei instrument around the _ method to form a single-stage electrical conversion H 'because this view of the road system sacrificed part of the God correction effect to obtain a good power S-number correction effect, but This leads to a reduction in the input of electricity. Because the full-bridge phase shift or the asymmetric half-bridge circuit is used in the known single-stage power converter, the flexible switching is done by the external resonant bridge and the parasitic capacitance of the switch. When the output is sharply increased or input into the light material, the circuit is a wire hard wire to provide sufficient holding time to ensure read stability 'so that this _ circuit reduction must be carried out under a relatively wide storage capacitor _ ' Qiao Na (10) secret bridge Wei Wei, will cause great = pass and switch loss. In addition, the full-bridge phase shift and the asymmetric half-bridge circuit are turned on due to the spectral inductance at light load. Fine, and Ruo Na _ operative low-power switch switching loss 'in the traditional series, parallel and series-parallel resonance design, must make the switching frequency M312840 __ only __ material pass, and __ upper _, high The circulation problem when working under the _ will cause serious damage and will not provide sufficient holding time. According to the company, this creation proposes a single-stage logic connection control power conversion device with high power input characteristics to solve the various shortcomings encountered in the prior art. [New content] * The main purpose of p is to propose a single-level logic connection control power supply and device for high-power features. The power factor correction unit is a boost converter and input. The voltage and input current are operated in the discontinuous conduction mode with the energy storage inductor to complete the function of spontaneous power correction. Therefore, the operation system does not need to add additional human side correction circuit and control, and no need to feedback the input current. Wave conversion ΓΓ 2 ' 提出 系 系 — — 种 种 种 种 种 种 种 种 高 高 高 高 单 单 单 单 单 单 单 单 单 单 单 单 单 单 单 单 单 单 单 单 单 单 单 单 单 单 单 单 单 单 单The controllable number is difficult, and the ant magnetization inductance is irrelevant to the storage capacitor voltage. Therefore, when the voltage of the impurity capacitor is higher and the load is lighter, the loop current of the charm is smaller. A further project of this creation proposes a single-level logic connection control lightning source conversion device with high power input characteristics, (4) logic axis " resonance frequency under the condition of 彳 _ / vibration early _ switching frequency system recording logic Connection control and the second _ connected to the whole, two two, so that the - side of the half-bridge switch single cut to zero voltage switching, change, effective ride. ^ 彳 = _ make the current in the touch _ first Wei to the material 剌 zero The problem of current cut-off is to improve the overall conversion efficiency in one step. Another purpose of this creation is to introduce a high-power single-level logic connection control power supply M312840 conversion device, which is used to convert the energy to read the energy balance to keep the output regulated. Reduce the storage capacitor voltage. In order to achieve the above purpose, the present invention provides a single-stage logic connection control power supply with high input due to input characteristics. The circuit domain includes a box-type power factor correction unit and a connection control relay conversion unit 7L and boost. The type of power is connected to the power supply, and the other end is electrically connected to the logic switch control unit through the consumption of the half bridge switch unit and the storage unit. Therefore, when the boosting power factor correction unit receives the input energy from the power source, it uses the half bridge to open the Luguan unit to input the output path of the mosquito energy, and transmits the input energy to the age unit. The energy storage can be used to receive the input energy stored in the storage unit and switch the energy according to different spectral frequencies. The power supply system in the above may be an AC power source or a direct (7) source, and the source between the money source and the boosting power factor correction unit may be a rectifier; the boosting force port positive unit 70 series includes at least—energy storage.

The specific examples are combined with the __ style to explain the purpose, the technical content, the characteristics and the achieved effects. [Embodiment] In the current energy shortage and the urgent need for energy saving, in order to enable the power conversion device to achieve the purpose of Wei environmental protection, the power factor and conversion efficiency have become the current power conversion device.

In the following, the implementation of this creation will be provided and the drawings will be accompanied by a detailed description of the technical features of the creation. The monthly test is not a picture of the younger brother, which is one of the high-performance input characteristics of the creation of the Cui-level logic = connected to the control of the electric_changing device block diagram, in this implementation secret, is the exchange of AC power For inputting the # to the boosting power factor correcting unit 4〇, and then inputting the input energy and the boosting power factor correcting unit 4G_half bridge_unit 5g to determine the input energy The output path ', the input energy is transferred to the memory unit 6〇 connected to the half-bridge switch unit 5, and the profit = store early read to store the input energy, and the logical connection control with the storage unit 6_ In the case of receiving the input energy stored in the storage unit 6〇, the switching of the energy according to the spectral frequency and the extinction is performed to switch the energy. In addition, in order to rectify the input energy, the The secret-rectifier commits between the parent current source 30 and the boost-type power factor correcting unit 4Q. In order to reduce the loop backflow in the device, the lower switch unit 5〇2 and the rectifier 32 can be connected to rectify the diode 9 M312840 body 402. The circuit architecture provided in the second figure is a single-level logic of the high-input input characteristics of the creation. The schematic diagram of the circuit connecting the control power conversion device, below, will reveal the actual circuit topology to be more detailed. The high-performance of this creation controls the actual operation of the power conversion device due to the single-stage logic connection of the input characteristics. Please refer to the third figure, which is an implementation of the circuit topology in the second figure. The AC power source 30 for generating energy is coupled to a rectifier 32, and coupled to the other end of the rectifier 32. The storage inductor 401 is connected to the half bridge switch unit 5〇, and the half bridge switch unit 50 is utilized to determine the transmission path of the input energy, wherein the half bridge switch unit % # It is composed of an upper bridge switch 胄 501 and a lower bridge switch 502, and in order to reduce the circuit backflow of the circuit, the lower bridge switch 502 is configured to rectify the diode 402, and is connected to the half bridge switch unit 5〇. The energy storage unit το 60 ' has two storage capacitors 6 (n, 6 〇 2 in the energy storage unit 60, which can be used to store energy, and the - end of the resonance capacitor 701 is simultaneously and two energy storage Capacitor ·6〇2 is lightly connected, and the other end is surface-to-drain inductor 702' and - transformer 704 is simultaneously connected with the leakage inductance 7〇2 and magnetizing inductance 7〇3, and is also coupled to the rectifying diode And the output wave capacitor, and the spectral capacitor 7〇1 is simultaneously with the leakage inductance 702 and the magnetizing inductance 703 Different vibration frequencies are used to determine the switching frequency of energy. φ For example, if the high-performance of this creation is due to the input characteristics, the single-stage logic connection controls the power conversion device. There are two _ members and ^, therefore, When the switching frequency is lower than the resonance frequency fs lower than the point 仏-higher than the resonance point f", after the signal is transmitted from the storage capacitor _, 602, it needs to pass through the two-phase-resonant 'phase-stage resonance system The spectral resonance capacitor 7〇1 and the leakage inductance 7〇2 are jointly performed, and the resonance of the second phase is involved in the addition of the magnetizing inductance 703. Please continue to refer to the third figure for the high power loss of the present creation. In the single-stage logic connection control power conversion device of human characteristics, the above two spectral points f and L can be divided into six working modes ' and at time points t0, t1, t2, t3, t4, T5, 16 as the interval, where the time is between t. The slave M312840 is the mode - the mode is between the t1 and t2 is the mode 2, the mode is between the μ is the mode 3, between t The mode is the mode 4, the mode 5 is between t4 and t5, and the mode is between ^. Therefore, the following will describe in detail the corresponding operation of the single-stage logic connection control power conversion device of the high-performance input characteristic of each creation in each mode: Mode 1 between ~ and ti: • The beginning of the series The lower bridge switch unit 5 () 2 is loaded, during which only the leakage inductance 7 () 2, the spectral capacitor 701 is oscillating, the primary current is a negative current, and the reverse current flows through the upper bridge switch. The parasitic one of the unit Xie's generates a zero voltage switching condition. The vibration currents are increased by the sine wave method, and the output current begins to increase after the secondary side transformation is 704. The magnetizing inductance 7〇3 clamps the output voltage. The home position is at the voltage value of nV. Therefore, the 'output voltage is across the secondary side of the transformer, and the magnetizing inductance is 疋. During this period, the energy storage inductor 4〇1 measures the release energy via the upper bridge switch unit to simultaneously charge the two storage capacitors 601 and 6〇2. Mode 2 between ti and t2: When the time is t!, the upper switch unit 5〇1 is turned on at zero voltage, and the magnetizing inductance is clamped at nV. Voltage. The leakage inductance is resonated with the spectral capacitance 7〇1, and the resonant current is charged by the sine wave electric charge to the storage capacitor, and the magnetizing current L is linearly increased at this time. Since the resonant current must conform to the relationship as shown in the following formula (1): ~ ir-iin+(I〇/n) (1) Therefore, current is transmitted to the load via the tertiary side rectifying diode 801. This mode ends when the time is seven and the spectral current is equal to the magnetizing current. At this time, the energy storage inductor 4〇1 continues to charge the second storage capacitors 601 and 602, and then the energy release is completed and the boosting power factor correction ends. Mode 3 between b and h·· M312840 When the time is t2, and the resonant current i is in the magnetizing current (4), the secondary side rectifying diode _ is switched off in the zero current switching state. However, the upper bridge switch unit is still turned on at this time, and the secondary side voltage of the transformer is lower than the output voltage. Therefore, the rectifier diode on the secondary side stops acting, and the exposed flow is supplied by the wave capacitor. . In the mode three, the leakage inductance, the magnetizing inductance 7G3 and the vibrating electricity are required to be oscillating, the day _ &, and the upper bridge unit is closed; ^ type one will end. Since the magnetizing inductance 7〇3 is extremely larger than the leakage inductance, in other words, the V-on time of the magnetizing inductance 703 is greater than the conduction time of the leakage inductance 7〇1, therefore, the spectral current and the magnetizing current approximate to the solid state value' while the upper bridge switch When the cell 5〇1 is turned off, its carrier current is less than the peak current of the spectrum. Mode 4 between t3 and t4: ^Field time is t* 'The upper bridge switch unit 5〇1 is cut off, and the parasitic capacitance of the lower bridge switch unit is discharged. White vibration motor 1 "The parasitic two of this lower bridge switch unit 5〇2 The pole body generates a zero voltage switching condition of the lower bridge switch unit 5. The oscillating current 4 is applied to the magnetizing current L, so that the secondary nano diode 01 is outputted by the V through the motor I. The magnetizing inductance is clamped to the voltage of a core. It can be regarded as the output voltage across the secondary side of the transformer 7 () 4. The mode 5 between seven and t5: the field time is (four) 'lower bridge switch unit The 5G2 system is turned on at zero voltage, and the input voltage after rectification is charged by the lower bridge switch unit 5G2 to charge the storage inductor 4Q1, so that the current of the storage inductor 4Q1 continues to rise, and the side vibration current lr is a sine wave current and Continue to decline, this mode only the leakage inductance view and the turtle capacitance 7G1 for the spectrum. The magnetization current L is a linear relationship from positive to negative, and the magnetization electric pick ο ο The relationship shown in the formula (1), when the magnetizing current W is represented by one side The whole body of the pole body 8〇1 is transmitted to the negative 胄, so that the spectral capacitance is caught and discharged. At the time, M312840 is t5' and the spectral current ir is equal to the magnetizing current 4, then mode five ends. Mode 6 between t5 and t6 · When the time is t5 'and the resonant current ir is equal to the magnetized cake", the secondary side rectifying diode is turned off in the state of zero current switching. At this time, the lower bridge switching unit The arc is still materialized, so that the current of the energy storage inductor 401 continues to rise until the time is seven, the end of the charging operation, the secondary side of the transformer is _ 晴, _: key ^ _ drum, coffee _ current The output wave capacitor _ should be. In mode 6, the leakage inductance is 7〇2, and the magnetization should be resonated simultaneously with the hybrid power system. When the time is t6 and the lower bridge switch unit is turned off, this mode ends. 'The magnetizing inductance is much larger than the leakage inductance view, which is similar to the case of mode 3. Since the conduction time of the magnetizing inductance is about the conduction time of the leakage inductance, the _current and the magnetizing current im approximate a fixed value. Verify the actual performance of the single-stage logic connection control power conversion device with high input due to the input characteristics disclosed in this creation. 'According to the circuit topology provided in the third figure, and the power supply with the voltage of other volts as the exchange, Lose _ v. For 28 scales, __ turn _The vibration frequency 匕 is 1〇2 kHz, the logical connection is __ rate w (four) 僧 ah, the cliff voltage is between 330 and 430 volts, and the maximum rim ray extraction point output ^ is 4.6 amps operating conditions Next, the per-component parameter in the circuit topology is as shown in the following list—and in the control circuit, the output dragon passes through the voltage dividing circuit and compares with the reference electrical quantity, and the obtained _Longxian signal is connected in parallel. After the voltage regulation magnetic=, it is sent to the inverter controller through the green combiner isolation, and the electric control system in the controller can be switched to the single-stage logic connection control power conversion device. The output voltage is stable within the specifications.

Therefore, according to the above operating conditions, first refer to the fourth figure, which is the current envelope of the energy storage inductor 4G1 in the third figure. The shape of the grid used in this figure is 1 ampere milliseconds, so the current envelope waveform can be observed, because the energy storage inductor operates in the discontinuous conduction mode, using the cutoff frequency at about _ switching The frequency input filter can eliminate the high-frequency signal, and according to the fifth figure, the lion's input dragon and current observation _ can be observed, the input current system has the following characteristics of the input voltage. And the result of the correction of the paste is due to the effect of the correction, and the mark used by this figure is your von b0 gang / 1 amp / 2 milliseconds. Therefore, according to the above operating conditions and with the work factor of (4) in the sixth 与The current harmonic distortion comparison table can be found to be 'under the mains voltage input, and the output is 1 () () ^, the temple, the measured power factor and total current harmonic distortion, the percentage of the touch data · The single-stage logic connection provided by the creation control M312840 power conversion device can maintain the performance of 〇·99 and above, and also meet the specifications of iec 1000-3-2 Class-D. In addition, using the spectral voltage and current waveform diagrams shown in the seventh figure, when the single-stage logic connection control power conversion device of the present invention enters the second interval (fs < fr), the two resonance modes of the resonant current appear. And the scale of the grid used in this figure is 20 volts / 1 volt / 1 amp / 4 microseconds; and in the switch zero voltage switching measured waveform diagram shown in the eighth figure, the indicator used The grid size is 100 volts / 〇 · 5 amps / 2 microseconds, and according to the zero-voltage switching measured waveform of the switch, the source voltage of the 汲 source has been reduced to zero before the switch is driven. Therefore, the power conversion efficiency can be used thereby. Increased; and in the secondary side rectified diode current waveform diagram shown in the ninth figure, the grid size used is 100 volts / 1 amp / 2 microseconds, according to the secondary side rectifying diode The current waveform shows that when the load is increased to 4.5A, the 'rectifier diode' is transmitted through the discontinuous conduction mode to achieve zero current switching. Therefore, in combination with the above results, in the tenth figure, the horizontal scale is the output current, the vertical axis is the conversion scale of the conversion efficiency, the power factor, and the total harmonic distortion are turned off. In Laizhong, it can be observed for this creation. Single-stage logic connection control weaving _ purely, because the "secondary side identification component implements flexible switching", the power conversion efficiency of the single-stage logic connection (4) power conversion device disclosed in this creation can be effectively improved to the right And 'in the change of the load, the single series of connected control power conversion disclosed in this solution (4) has a good power factor correction effect of G. 99 or more, and the total Wei distortion also conforms to IEC 1000-3-2 Class- The spectral wave standard of D. According to the above-mentioned system, a single-stage logic connection control power conversion device with high input due to input characteristics disclosed in the present invention, in which the energy storage inductance system operates in a discontinuous conduction mode, is responsible for the correction of the power supply. , indeed round (four) (four), in other words, if there is a current input, it can automatically follow the input voltage to achieve the spontaneous power factor correction, in order to achieve high power 15 M312840 due to the input. And 'because the logic is connected to the relay unit, the current is determined by the size of the magnetizing inductance, instead of the _transmission of the load or the storage capacitor, so the capacitor voltage is higher or the load is higher (four) 'turned to the ring The power supply and the guide line can be effectively reduced. In addition, the half-bridge switch unit turn-on voltage conduction is only related to the magnetization button, but not related to the aerostatic capacitance or (four) size. Therefore, the κ bump is rarely greater than the _capacitance, and the Wei The spectral frequency, the half-bridge switching unit can be turned on under zero voltage conditions, therefore, the creation can have a relatively wide (four) switching range. However, for the secondary side rectifier reverse recovery problem, due to the high work of this creation Because of the single-level logical connection of the input, the four-level logic connection (4) is transferred to the county Wei Ke Qian Zhen _ to rectify the current of the rectifier to zero, and the zero-current switching is realized in the state where the Wei-to-wire is set to be scrapable and connected. The problem of recovering the loss does not exist. Therefore, the high-performance single-level logic connection control power conversion device of the present invention adopts the frequency conversion control method to achieve the voltage stabilization effect, so that the overall The power conversion device has the characteristics of high power, high efficiency, low cost, etc. Moreover, the high-performance single-level logic connection control power conversion device of the present invention is in a reasonable fiber, and the highest conversion scale can be high. And the cause can reach 0.99 or more, and at the same time, it is easy to meet the requirements of the international __2(5)(4). The above description illustrates the characteristics of the creation by the embodiment, and the purpose is to enable the person familiar with the technology to understand the creation (4) The domain is implemented, and the patents of this creation are fine. Therefore, any equivalent modifications or modifications not to be removed from the spirit of this creation should be included in the scope of the application described in the town.
