Description of the Invention: [Technical Field] The present invention relates to an electronic ballast, and more particularly to an electronic ballast having a continuous current type power factor corrector. With the development of technology and the improvement of living standards, lighting has become an indispensable basic requirement in human life. In recent years, due to the booming development of various industries around the world, the frequent commercial activities and the improvement of the quality of life at home, the lighting power is also increasing day by day, making the development of lighting systems that are efficient, comfortable, safe and economical more and more important. Among them, fluorescent lamps have become the mainstream of today's lighting systems due to their high luminous efficiency, long life, low lamp temperature, light color and multi-shape. Fluorescent lamps, like most gas discharge lamps, exhibit electrical characteristics of negative incremental resistance and require a ballast to limit the current flowing through the lamp. Fluorescent • The ballast of the lamp must have the function of starting the fluorescent lamp in addition to the current limiting function. The fluorescent lamp is activated by providing a high voltage to cause the discharge of free gas. After the fluorescent lamp is activated, it is only necessary to maintain a small electric power to maintain the gas discharge current of the fluorescent lamp. Conventional stabilizers are in the form of electromagnetic operations. Although the electromagnetic ballast has the advantages of durability and simple structure, it has disadvantages such as low efficiency, large volume, heavy weight, easy noise generation and low frequency flicker. For modern and increasingly diverse luminaire applications, electromagnetic ballasts are increasingly unable to meet the demands of use. Compared with electromagnetic ballast electronics, the 5 1336485 ballast has the advantages of fast start, no flicker, high luminous efficiency and high power factor. It can save a lot of electric energy compared with electromagnetic ballast. Therefore, electronic stabilizers have gradually replaced the status of electromagnetic ballasts. The power supply used in general electronic ballasts is direct current, but the power supply currently supplied by the power system is alternating current. Therefore, most of the current use of a two-pole full-wave rectifier circuit or a voltage doubler rectifier circuit converts the AC power supplied by the power system into DC power for use by the electronic ballast. Therefore, in order to eliminate the rectified AC component, a large capacitor is used in parallel with the DC to obtain a stable DC voltage. However, it is because this capacitor maintains the DC voltage at a fixed level, so that the rectifier can only be turned on when the amplitude of the AC voltage is higher than the capacitor voltage, and the required power is drawn from the power supply portion. • The rectifier is turned on for very short periods of time during each input power cycle and 'has a large pulse inrush current during this time period. The inrush current appears as a pulse near the peak of the AC source voltage. This current waveform contains high harmonics and produces a low power factor non-φ good effect at the AC source. The reduction in power factor not only reduces the utilization factor of power equipment (such as transformers) in the system, but also forces the rated capacity of the relevant components and equipment to be increased to supply the load. In addition, high harmonic currents often cause malfunctions in the control circuit and power protection equipment, and the measurement instrument or communication system is disturbed, and the waveform of the power supply voltage is affected to be distorted. Therefore, how to improve the power factor and reduce the total harmonic distortion is an important issue in the design of electronic ballasts. 6 1336485 SUMMARY OF THE INVENTION Accordingly, it is a primary object of the present invention to provide an electronic ballast for activating and maintaining a fluorescent lamp load. Another object of the present invention is to provide an electronic ballast having a power factor corrector. It is still another object of the present invention to provide an electronic ballast that operates in a continuous current mode. A further object of the invention is to provide an electronic ballast suitable for use in high power applications. In order to achieve the above object of the present invention, an electronic ballast according to an embodiment of the present invention includes an AC voltage source, a rectifier, a power factor corrector, an inverter, and a resonance circuit. The rectifier is used to rectify the AC house provided by the AC source to a DC voltage, so that the inverter (4) • uses a DC voltage to switch the high frequency AC square wave voltage. The components in the resonant circuit are capable of resonating with each other and filtering the high frequency alternating square wave generated by the inverter by the harmonic impedance generated by the resonance. The high frequency AC square wave after filtering is converted into a sine wave suitable for use in a fluorescent lamp load. In addition, the power factor corrector is a DC-to-DC converter circuit, which enables the input current waveform to follow the input voltage waveform to achieve. (4) The function of the correction and the detection of the input and output power _ Required for fluorescent lamp loads of different powers. In an embodiment consistent with the present invention, the power factor corrector operates in a continuous t-stream mode to reduce the ♦ value current of the components in the power factor corrector, so that the electronic ballast in accordance with the present invention is suitable for use in demanding output. Power application 7 1336485 occasion. [Embodiment] Since the general electronic ballast has problems of low power factor and high harmonic distortion, the basic concept of the present invention is to add a power factor corrector to the electronic ballast to improve the power factor. Reduce harmonic distortion. Wherein, the power factor corrector proposed in the embodiment of the present invention operates in a continuous current mode to reduce the electrical strength required for each component in the circuit, so that each component can have a lower electrical capacity and Cost and make the circuit more suitable for high power applications. Fig. 1 is a circuit diagram showing an electronic ballast 1〇〇 in accordance with one of the concepts of the present invention. Wherein, the AC voltage source i02 provides the power source of the entire circuit, but since the power source required for the subsequent circuit is a DC power source, it is necessary to first rectify the AC power output from the AC voltage source 102 to the DC power via the rectifier 104. Subsequent circuit transmission. Then, by the fast switching of the converter 108, the DC voltage output from the rectifier 104 can be switched to a high-frequency square wave voltage. In the resonant circuit 11A, the inductive and capacitive elements are used to generate a resonance effect. When the high-frequency square wave voltage outputted by the inverter 108 is filtered by the resonant impedance, it appears close to the load terminal 112. The sine wave voltage and current are used to supply the fluorescent lamp load. In addition, the resonant circuit 110 can generate a sufficiently high lamp starting voltage across the load before the fluorescent lamp load is activated to cause the lamp to enter a lighting state. The power factor corrector 106 is coupled to a DC-to-DC converter circuit after the rectifier 104 to accommodate different power requirements of the load. And the timing of the control switch is switched to enable the energy storage circuit to store and release energy, so as to change the input power and current waveform, so that the input current waveform can follow the waveform of the input voltage. Through appropriate operating procedures, the waveform and size of the input current can be accurately controlled to achieve power factor correction and voltage regulation. According to the experimental result, after the power factor correction circuit 106 is added to the circuit of the electronic ballast 1〇〇, the harmonic distortion can be suppressed to almost no existence, the power factor is almost close to one' and the input power source and the load are allowed to be quite large. The scope of the change. Wherein the power factor corrector 1 〇 6 proposed in the embodiment of the present invention operates in a continuous current mode, that is, the current flowing through the components in the power factor corrector i 〇 6 has only a small peak, which also makes The cut-off loss and conduction loss of the circuit at the time of switching are reduced. Therefore, an electronic ballast having a continuous current type power factor corrector is particularly suitable for applications requiring a high power output. The following series of embodiments are described to illustrate the circuit aspects that can achieve the object of the present invention. Fig. 2A is a circuit diagram showing an electronic ballast in accordance with a first embodiment of the present invention. The power supply of this electronic ballast is provided by an AC voltage source 2〇2. The AC power supply provided by the AC voltage source first filters the high frequency noise through a filter composed of the filter inductor 204 and the filter capacitor 2〇6 to ensure the quality of the power supply. The filtered AC power is supplied to a half-wave rectifier composed of a first rectifying diode 212 and a second rectifying diode 214 via a first energy storage inductor 222. An inverter composed of a first switching element 232 and a second switching element 234 is connected in parallel with the half-wave rectifier, wherein the first switching element 232 1336485 and the first switching element 234 can be, for example, a gold-oxygen half-field power supply. A switching element such as a crystal (M〇SFET) is implemented, so that the first switching element 232 and the second switching element 234 are represented by an equivalent circuit of a switch plus a transistor in the figure. Therefore, as can be seen from FIG. 2A, the half-wave rectifier composed of the first rectifying diode 212 and the second rectifying diode 214 is connected in parallel with the first switching element 232 having the equivalent diode and The second switching element 234 can actually implement the function of a full wave filter. The resonant circuit in the circuit is composed of a first resonant capacitor 242, a resonant inductor 244 and a second resonant capacitor 246. The two ends of the resonant inductor 244 are connected in series with the first resonant capacitor 242 and the second resonant capacitor 246 , and the other end of the first resonant capacitor 242 is connected to the first rectifying diode 212 and the second rectifying diode 214 . The other end of the second resonant capacitor 246 is connected between the first switching element 232 and the second switching element 234. Both ends of the second load capacitor 246 are used in parallel with the fluorescent lamp load 252. In addition, a storage capacitor 216 is connected in parallel with the entire half-wave rectifier, a first feedback capacitor 224 is connected in parallel with the first rectifier diode 212 in the half-wave rectifier, and a second feedback capacitor 226 and a half-wave rectifier are included. The second rectifying diodes 214 are connected in parallel. As described above, after the half-wave rectifier composed of the first rectifying diode 212 and the second rectifying diode 214 is connected in parallel with the inverter composed of the first switching element 232 and the second switching element 234, The effect of full-wave rectification can be obtained, and therefore, the negative electrode of the first rectifying diode 212 can provide a rectified positive voltage. Moreover, because the half-wave rectifier is connected in parallel with a 10 1336485 storage capacitor 216, the negative pole of the first rectifying diode 212 can provide a relatively stable DC positive voltage. In this circuit, there is an additional control circuit (not shown) that controls the switching of the first switching element 232 and the second switching element 234. Generally, the first switching element 232 and the second switching element 234 are quickly switched in opposite phases to each other to output a high-frequency square wave voltage at the intermediate connection between the two. After resonantly filtering the resonant circuit composed of a resonant capacitor, a resonant inductor, and a second resonant capacitor, a voltage and current similar to a sine wave can be generated across the load 252. When the second switching element 234 is in the switching operation, a large current is caused to flow through the resonant circuit and the second switching element 234, and the current of the large current flowing through the first energy storage inductor 222 is large, so In addition to the current flowing through the first energy storage inductor 222, the storage capacitor 216 also releases the stored electrical energy via the first feedback capacitor 224 to support the large current through the second switching element 234, and simultaneously for the first feedback. Capacitor 224 is charged. The current flowing in the second switching element 234 is not greatly increased by the presence of the first energy storage inductor 222. In addition, because of the existence of the first feedback capacitor 224, the storage capacitor 216 has a feedback path, so that the stored energy stored in the first energy storage inductor 222 is not exhausted once, so that the first energy storage inductor 222 passes. The current becomes discontinuous. These features make the current through the various components in the circuit not change instantaneously, reducing the electrical specifications required for each component. Then, when the entire circuit reaches a balance, the flow through the first energy storage inductor 222 is greater than the current flowing through the resonant circuit. At this time, in addition to the first rectification 11 1336485 diode 212 is turned on, the first feedback capacitor 224 will also transfer the stored electrical energy back to the storage capacitor 216. Through such a power transfer action, the power factor of the circuit can be maintained to a certain extent. In addition, the function of the second feedback capacitor 226 is the same as that of the first feedback capacitor 224, but the second feedback capacitor 226 is operated at the moment when the first switching element 232 is switched 'relative to the first feedback capacitor 224. It is acting on different high frequency square wave periods. Therefore, there may be only the first feedback capacitor 224 or the second feedback capacitor 226 in the circuit, and may also have the first feedback capacitor 224 and the second feedback capacitor 226, each having different energy transfer effects. It depends on the actual application. Fig. 2B is a circuit diagram showing an electronic ballast in accordance with a second embodiment of the present invention. The circuit depicted is the same as that shown in Figure 2A. However, the original first energy inductor 222 is replaced by a second energy storage inductor 228. One end of the second energy storage inductor 228 is connected between the AC voltage source 2〇2 and the filter capacitor 206, and the other end is directly connected between the first switching element 232 and the second switching element 234. Because the power supply of the circuit is the alternating current provided by the alternating voltage source 202, although the connection is different, the second energy storage inductor 228 can still achieve the same function as the first energy storage inductor 222. Therefore, in the second diagram. The first energy storage inductor 222 shown and the second energy storage inductor 228 shown in the second diagram can be present at the same time, which also has the effect of increasing the total inductance of the energy storage inductor. Fig. 3 is a circuit diagram showing an electronic ballast in accordance with a fourth embodiment of the present invention. The circuit circle shown in Figure 3 is changed from the circuit diagram shown in Figure 2, where the first feedback 12 1336485 capacitor 224 and the second feedback capacitor 226 in the circuit shown in Figure 2 are removed. And another feedback capacitor 322' is added, wherein the feedback capacitor 322 is connected in parallel with the resonant circuit composed of the first resonant capacitor 242, the resonant inductor 244 and the second fault capacitor 246. • Thus, when the current flowing through the resonant circuit is large, the feedback capacitor 322 can be charged together. When the current flowing through the storage inductor 222 is large, the feedback capacitor 322 can be passed through the first rectifying diode 212. The electrical energy is transferred to the storage capacitor 216 for energy transfer purposes. Fig. 3B is a circuit diagram showing an electronic ballast in accordance with a fourth embodiment of the present invention. The circuit depicted is the same as that shown in Figure 3A, but the original first energy storage inductor 222 is replaced by a second energy storage inductor 228. One end of the second energy storage inductor 228 is connected between the AC voltage source 2〇2 and the filter capacitor 206, and the other end is directly connected between the first switching element 232 and the second switching element 234. Since the power supply of the circuit is the alternating current provided by the alternating voltage source 202, although the connection is different, the second energy storage inductor 228 can still achieve the same function as the first energy storage inductor 222. Therefore, FIG. 3A The first energy storage inductor 222 shown in FIG. 3 and the second energy storage inductor 228 shown in FIG. 3B can exist at the same time, which also has the effect of increasing the total inductance of the energy storage inductor. - Fig. 4A is a circuit diagram showing an electronic ballast in accordance with a fifth embodiment of the present invention. The circuit is changed by the circuit shown in FIG. 8 , wherein a half-wave rectifier connected by a third rectifying diode 412 and a fourth rectifying diode 414 is added, and The half-wave rectifier formed by the first rectifying diode 212 and the rectifying diode 214 is connected in series to become a full-wave rectifier β. In addition, since the full-wave 13 1336485 rectifier is used in the circuit, A current limiting diode 416 is also connected in series between the full-wave rectifier and the storage capacitor 216 to prevent current from flowing back. The positive pole of the current limiting diode 416 and the first rectifying diode 212 and the third rectifying diode The negative electrode of the body 412 is connected, and the negative electrode is connected to the storage capacitor 216. Similarly, in the circuit shown in FIG. 4A, the first feedback capacitor 224 and the second feedback capacitor 226 also provide a voltage regulation function for the voltage outputted by the full-wave rectifier, and can be used in the current limiting diode. When 416 is turned on, the stored electrical energy is transferred to the storage capacitor 216. Therefore, the effect of the second feedback capacitor 226 is the same as that of the first feedback capacitor 224. Therefore, there may be only the first feedback capacitor 224 or the second feedback capacitor 226 in the circuit, and may also have the first feedback capacitor 224 and the second feedback capacitor 226, each having different energy transfer effects. It depends on the actual application. Fig. 4B is a circuit diagram showing an electronic ballast in accordance with a sixth embodiment of the present invention. The circuit depicted is the same as that shown in Figure 4A, but the first first energy storage inductor 222 is replaced by a second energy storage inductor 228. One end of the second energy storage inductor 228 is connected between the AC voltage source 2〇2 and the filter capacitor 206, and the other end is directly connected between the third current limiting diode 412 and the fourth current limiting diode 414. Because the power supply of the circuit is the alternating current provided by the parent voltage source 202, although the connection mode is different, the second energy storage inductor 228 can still achieve the same effect as the first storage inductor 222. Therefore, FIG. 4A The first __ energy storage inductor 222 shown in the figure and the second energy storage inductor 228 shown in FIG. 4B can exist at the same time, and this also has the effect of adding the total inductance value of the energy storage inductor.

Therefore, the first feedback capacitor 224 will still be in parallel with the first rectifier diode 212, and the second feedback capacitor 226 will still be in parallel with the second rectifier diode. However, in order to cooperate with the addition of the first feedback capacitor 226, the second resonant capacitor must be connected to the anode of the second rectifying diode 214 to be connected to the cathode of the second rectifying diode 214.

在本電路中’由於第一回授電容224以及第二回授電 容226的加入，增加了回授電容的儲能容量，也使得本電 路之功因修正效果更為顯著。 第9Β圖繪示了符合本發明之第十六實施例之電子式 安定器之電路圖。其所繪示之電路與第9Α圖所繪示之電路 相同’但原本之第一儲能電感222係為一第二儲能電感228 所取代。第二儲能電感228之一端連接於交流電壓源202 與濾波電容206之間，而另一端則直接連接於第一開關元 件232與第二開關元件234之間。因為本電路之電源是由 交流電壓源202所提供之交流電，所以雖然連接的方式不 20 1336485 同，但第二儲能電感228仍然能夠達成和第一儲能電感222 相同的作用，因此，第9A圖中所示之第一儲能電感222 與第9B圖中所示之第二儲能電感228是能夠同時存在的， 此舉也有著增加儲能電感總感值的效果。 最後要特別說明的是’在上面所列舉的實施例當中， 共振電路皆是以電容及電感元件的組合來達成，但是在實 際應用上· ，也可使用壓電變壓器來實現共振電路的作用。 雖然本發明已以一較佳實施例揭露如上，然其並非用 以限定本發明，任何熟習此技藝者，在不脫離本發明之精 神和範圍内，當可作各種之更動與潤飾，因此本發明之保 護範圍當視後附之申請專利範圍所界定者為準。 【圖式簡單說明】 為讓本發明之上述和其他目的、特徵、優點與實施例 能更明顯易懂’所附圖式之詳細說明如下： 第1圖為符合本發明實施例之電子式安定器之架構圖。 第2A圓為符合本發明第一實施例之電子式安定器之 電路圖。 第 2B 圖氣 吗马符合本發明第二實施例之電子式安定器之 電路圖》 第3A圖為符合本發明第三實施例之電子式安定器之 電路圖》 第3B圖兔外 ’得合本發明第四實施例之電子式安定器之 21 1336485 電路圖。 電路I从圖為符合本發明第五實施例之電子式安定 第4B圖為X 電路圖。 。本發明第六實施例之電子式安定 電路I。 _為符合本發明第七實施例之電子式安定 電二。5B圖為符合本發明第八實施例之電子式安定器之 電路圖。圖為符合本發明第九實施例之電子式安定 電路圖。圖為符合本發明第十實施例之電子式安定器之 之電路圖。4符合本發明第十&quot;&quot;實施例之電子式安定器 之電路圖。4符合本發明第十二實施例之電子式安定器 之電圖為符合本發明第十三實施例之電子式安定器 之電ίΓ/為符合本發明第十四實施例之電子式安定器 之電：Γ圖為符合本發明第十五實施例之電子式安定器 器之 器之 器之 器之 第9Β圖為符合本發明第十六實施例之電子式安定 器 22 1336485 之電路圖。 主要元件符號說明 100 :電子式安定器 102 ： 交流電壓源 104 :整流器 106 ： 功因修正器 108 :換流器 110 : 共振電路 112 :負載端 202 ： 交流電壓源 204 :濾波電感 206 ： 濾波電容 212 :第一整流二極體 214 ： 第二整流二極體 216 :儲能電容 222 ' 228、722 :儲能電感 224 ' 522 ' 622 ' 724 ： 第一回226、 524、624、726 :第二回 授電容 授電容 232 ··第一開關元件 234 ： 第二開關元件 242、542、742 :第一 諧振電244、 544、744 :諧振電感 容 246、546、746 :第二 諧振電252 ·’ 負載 容 322 ' 822 ：回授電容 412 ： 第三整流二極體 414 :第四整流二極體 416 ： 限流二極體 712 :第一限流二極體 714 ： 第二限流二極體 23In the present circuit, due to the addition of the first feedback capacitor 224 and the second feedback capacitor 226, the energy storage capacity of the feedback capacitor is increased, and the power of the circuit is more significantly corrected. Figure 9 is a circuit diagram showing an electronic ballast in accordance with a sixteenth embodiment of the present invention. The circuit depicted is the same as that shown in Figure 9 but the original first energy storage inductor 222 is replaced by a second energy storage inductor 228. One end of the second energy storage inductor 228 is connected between the AC voltage source 202 and the filter capacitor 206, and the other end is directly connected between the first switching element 232 and the second switching element 234. Because the power supply of the circuit is the alternating current provided by the alternating voltage source 202, although the connection mode is not the same as 20 1336485, the second energy storage inductor 228 can still achieve the same function as the first energy storage inductor 222, therefore, The first energy storage inductor 222 shown in FIG. 9A and the second energy storage inductor 228 shown in FIG. 9B can exist simultaneously, and this also has the effect of increasing the total inductance of the energy storage inductor. Finally, it should be particularly noted that in the above-exemplified embodiments, the resonant circuit is realized by a combination of a capacitor and an inductor element, but in practical applications, a piezoelectric transformer can also be used to realize the function of the resonant circuit. Although the present invention has been described above in terms of a preferred embodiment, it is not intended to limit the invention, and it is obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention. The scope of the invention is defined by the scope of the appended claims.
