Technical field

Belong to electronic technology field.

Background technology

Power supply is the most important elementary cells of all electronic circuits, and its reason is, all electronic equipments be required to reliable and Stable power supply.The quality of a kind of electronic equipment is the most relevant with power supply.Power source performance is good, then overall performance is good.Power supply is the most normal It is often flimsy Focusing on components, and the infringement caused with overvoltage of being struck by lightning is one of main source of fault, so, study one Plant the regulated power supply reducing this fault rate, be the most significant.

Present product makes rapid progress, and traditional power supply voltage regulation way has been not applied for the sci-tech product of modern innovation, Once multiple product about security personnel's equipment had been applied for such as this enterprise.The product of these equipment is the highest to the requirement of power supply, overcritical Degree will significantly larger than ordinary electrical home appliance, be inefficient by traditional design.Reason is as follows:

One be power supply be often electrical equipment, the most troublesome keypoint part, the most such to ordinary electrical home appliance.And to being furnished with electric power storage The product in pond is all the more so, because during with accumulator, and the most only load power source, add again the charging current filling accumulator, If accumulator electricity consumption is too much, initial charge stream is very big, thus more exacerbates the load of power supply, thus is easily damaged.

Two is the ordinary electrical home appliance same day at thunderstorm season, can pull out power supply prevention, in the needs used time, (if desired for seeing electricity Apparent time) because being easily alerted, can recover immediately, user is expected.And series products of ensuring public security is the most highly difficult, because dialling Behind power down source, being difficult to intuitively remind, because in the life of high rhythm, forget about that these things are possible, now its protection function is just Malfunctioning, produce security personnel's blank.If user is forgotten to recover, then security personnel will be in security personnel's blank for a long time.And present stable state collection Become in lightning protection, the most weak, as generally input ceiling voltage is only about 30 volts.

The particularity importance of three products being because security personnel, it is therefore necessary to have when design and adapt to electrical network change Wider, key benefit reason one is when voltage ripple of power network, will not originally penetrate integrated regulator and cause damage.Reason Two are, civil power relatively low or relatively high time can normal voltage stabilizing, do not result in the malfunctioning of protection function.Reason three is to make security personnel Product can have bigger use space.

Four is that security personnel's series products necessarily joins accumulator, and the maintenance of accumulator has higher requirement, wherein charging voltage It is worth different with place value.If load request voltage stabilizing is pressed in voltage stabilizing, then can not meet the requirement of charging, if by the voltage of charging As requiring, then load will be higher than normal required voltage for a long time.This is difficult point one.Difficult point two is if there being battery discharging system System, inevitable is formed or door power supply mode load with mains-supplied system, therefore both be loaded with or the circuit of door character. During battery discharging, most of time is often to save the standard value of 2 volts, and along with discharging, this value also to decline, the therefore output of accumulator Voltage drop is of great value, if or the pressure drop of circuit of door character excessive.The normal standard of deviation then loaded strengthens.Therefore use Any measure makes accumulator not produce too much pressure drop when electric discharge, becomes difficult point.Difficult point three is Set of system, and be that battery system is powered during without civil power, conversion between the two is to automatically switch, the most how could be real Now change scientific.Difficult point four is how to form two parts to power and be independent of each other each other, is i.e. when accumulator breaks down, no Mains-supplied system can be affected, otherwise do not interfere with battery system during mains-supplied system failure.Difficult point five, some data carry Going out and make to switch with relay, this scheme has multiple deficiency, and wherein the point of an important deficiency is power consumption, and difficult point six is, some Scheme cost is too high, is not suitable for the universal of product.

Just because of above-mentioned factor so that the development of power supply receives obstruction, the performance of electronic product to be made obtains more The most perfect, it is necessary first to be exactly the innovation of power supply, so needing brand-new thinking to carry out perfect to power supply.

One, this practical Alternating Current Power Supply dependable performance.

Alternating Current Power Supply have employed preposition voltage stabilizing and combines with the three end integrated voltage-stabilizeds having monitoring, both ensure that three ends will not damage Bad, formed again the monitoring of stream, technical staff both knows about, and three end integrated stable voltage circuits are kind of outstanding circuit, but due to defeated Entering voltage low, the highest input value is 36V, once will result in infringement more than 36V, if subjected to thunderbolt, it is likely that can be higher than 36V, so devising preposition voltage regulation unit, it is ensured that three ends will not damage in the present invention.

1, the explanation of preposition voltage regulation unit: the input of three terminal regulator (in Fig. 1 5.11) terminates preposition voltage stabilizing audion The emitter stage of (in Fig. 1 5.01), preposition voltage regulation resistance (in Fig. 1 5.02) is connected on colelctor electrode and the base of preposition voltage stabilizing audion Between pole, base stage is two-way, and a road connects preposition backup stabilivolt (in Fig. 1 5.03) and arrives ground wire, and a road connects preposition work voltage stabilizing Pipe (in Fig. 1 5.05) preposition adjustment resistance (in Fig. 1 5.06) of connecting is to ground wire, and the colelctor electrode of preposition voltage stabilizing audion meets guarantor Protect the second transfer contact of relay (in Fig. 1 2.1).Preposition voltage stabilizing audion is high back-pressure large power triode, therefore has The strongest overvoltage capabilities.

Preposition voltage regulation unit need not voltage the most accurately, thus, it is not necessary to too much debugging, the work stabilivolt of its base stage With backup stabilivolt, further improve the voltage regulation performance of voltage stabilizing audion, during design, the voltage stabilizing voltage ratio of work stabilivolt The voltage stabilizing voltage of backup stabilivolt is low, thus backs up stabilivolt in a dormant state at ordinary times, and no current passes through, when there being overvoltage, Adjustment resistance both end voltage is made to increase, after making the voltage of work stabilivolt branch road be higher than the voltage stabilizing voltage of backup stabilivolt, backup Stabilivolt is open-minded, again to base stage pressure limiting, it is ensured that it is reliable that preposition voltage regulation unit exports.

2, the explanation of overcurrent monitoring: power supply is the vitals of all electronic circuits, is also the most flimsy parts, when setting Standby break down or time power supply itself goes wrong, produce electric current excessive, now can notify user in time, allow a user in time Safeguarding, this is highly important, because it can reduce the spoilage of equipment and power supply, this is not only a kind of lifting to power supply, For the electrical equipment that some maintenace points are few, this it is critical that, because maintenance inconvenience, again or since it is desired that and luck With, if it occur that fault and fail to learn in time, being just eager to look for people to keep in repair when using, this obviously brings to user greatly Inconvenience.Accordingly, it is capable to the power supply actively monitored and point out is the most necessary.

Had a fault or time three terminal regulator itself breaks down arranging, monitoring instruction can be accomplished.When arranged standby Break down, make electric current increase, or three terminal regulator itself goes wrong, and makes output end current increase, flows to threshold resistance The electric current of two (in Fig. 1 5.14) increases, and makes the pressure drop at threshold resistance two two ends increase, and conducting family of power and influence's audion is (in Fig. 1 5.15) conducting, luminous indicating lamp (in Fig. 1 5.16) sends light.

And under normal circumstances, family of power and influence's audion does not turns on, because not changed by the pressure drop of threshold resistance, therefore, Family of power and influence's audion will not start.

3, there is the explanation of wider mains input voltage.

A, the scope that civil power is wider can be operated in.

Being high-power high countervoltage triode in circuit, the back-pressure of its colelctor electrode may be up to 300 volts, so mains transformer The voltage of secondary side can be suitable higher, when therefore civil power is relatively low, the voltage of the secondary side of mains transformer remains to meet device The requirement of part.And when therefore civil power is higher, its rectification output is still not above 300 volts, thus it is unlikely to preposition voltage stabilizing list Audion in unit damages.So the present invention can be operated in electric hypodynamic place, and in the too strong place of electric power also Without compromising on.

B, be difficult to when unexpected fluctuation occurs in civil power damaged.

Also because of above-mentioned reason, so when civil power unexpected fluctuation, will not damage easily.

Two, this utility model has the explanation that overvoltage protection is good.

There is good anti-overvoltage protection explanation: the lightning protection stabilivolt that protective relay is connected suctions through, and its correspondence is normally closed Contact disconnects, and rear class is formed protection quick-break, therefore to protected effect of being struck by lightning, forms a kind of special protection.This protection shape The principle become is, cut off rear class rather than short circuit, so good effect, at numerous equipment of many Compact Power Plants Lightning protection, it is simply that use this fast tripping protection.The stabilivolt connected due to protective relay is flexible, it is possible to form institute The anti-overvoltage grade needed.This lightning-arrest pipe being common is difficult to, because the lightning-arrest pipe of less than 100 volts is difficult to buy, and The anti-thunder tube of less than 50 volts almost can't buy.

The explanation of three, independent charge circuit feature.

It not in high-grade pressure stabilizing device, it is difficult to ensure that there is the accumulator of floating charge with civil power is powered simultaneously, there is height The unification of degree.This measure have employed special design, by completely separable with load circuit for the most supporting floating charge loop, thus tool There is good advantage.Now as a example by load needs 12 volts, if the accumulator of adapted 12 volts.Then during accumulator floating charge, need About 13.8 volts, if not designing special circuit, then when civil power has electricity, power output end is about 13.8 volts for a long time, and this is right The load only needing 12 volts is unfavorable.If power end output is adjusted to 12 volts, though load request can be met, but departing from accumulator Needed for floating charge 13.8 volts.Its floating charge principle is, when civil power has electricity, bridge rectifier unit one output has electricity, through floating charge three pole Pipe, then the earth terminal of bridge rectifier unit one is returned to through accumulator, also it is the negative terminal of accumulator, thus forms floating charge and independently return Road, according to kirschner law, and the experiment of circuit, this floating charge loop is self-existent, with three end monitoring voltage regulation units to negative The current supply circuit carried does not interfere with each other, and ac power supply circuit is the output electric current of bridge rectifier unit two to the current supply circuit of load, Through three ends monitoring voltage regulation units to load, it is then return to ground wire, that is to say the earth terminal of bridge rectifier unit two.

This practical accumulator floating charge uses the science charging modes filling not only but also stopping, and accomplishes the scientific maintenance to battery, Maximized prolongation is electrically charged life-span and the capacity in pond.

Pulse charge unit is by floating charge audion (in Fig. 1 8), trickle resistance (in Fig. 1 7), pulser (in Fig. 1 10.1), oscillation resistance (in Fig. 1 10.13), oscillating capacitance (in Fig. 1 10.15), pulse ratio relatively go up inclined resistance (in Fig. 1 10.11), pulse ratio relatively under inclined resistance (in Fig. 1 10.12) composition.

The charge rule coexisted at charge and discharge is, within a cycle of pulse, when pulser output low level, floating Filling audion and open charging, when pulser output is high-order, floating charge audion cuts out, and stops charging, and such charging modes is favourable In the scientific maintenance to battery, the battery damaged also there is a certain degree of restitution simultaneously.

The reason forming so charging is: when accumulator underfill electricity, stops filling device (in Fig. 2 10.20) and is output as Low level, because the voltage of in-phase end the most not up to stops to fill stopping filling and comparing voltage branch (in Fig. 2 10.22) and formed of device end of oppisite phase Comparison voltage, so it is output as low level, the now starting of oscillation of pulser, oscillation resistance to oscillating capacitance charge, pulse The homophase of device has terminated pulse ratio relatively voltage branch, defines the threshold voltage of pulser, when the voltage of oscillating capacitance reaches this During individual threshold voltage value, pulser output low level, floating charge audion is connected, and charges to accumulator (in Fig. 2 9.1), vibration electricity Hold and discharged to pulser outfan by oscillation resistance, when being put into the comparing voltage value less than pulser in-phase end, pulser An output high position, floating charge audion disconnects, and accumulator stops charging, and oscillation resistance starts again to charge, the most so to oscillating capacitance Circulation is until the magnitude of voltage of accumulator reaches the comparing voltage value stopping filling device end of oppisite phase.

After the voltage of accumulator is charged to a definite value (being i.e. the comparing voltage value stopping filling device end of oppisite phase), accumulator is stopped Fill floating charge, by the trickle resistance (in Fig. 1 7) trickle needed for accumulator provides.

Stop filling unit by stopping filling device (in Fig. 1 10.21), stopping filling diode (in Fig. 1 10.16), stop filling in comparison partially Resistance (in Fig. 1 10.22), stop filling under comparison inclined resistance (in Fig. 1 10.23) composition.

The end of oppisite phase stopping filling device be connected to stop filling in comparison inclined resistance with stop filling compare under resistance partially form that to stop filling device anti-phase The threshold voltage of end, its principle is, when accumulator floating charge to this threshold value, stops filling device and exports high pressure, fills diode by stopping Allowing pulser failure of oscillation, pulser export a high position, floating charge audion disconnects, and stops charging to accumulator.

Four, civil power and accumulator duplicate supply explanation.

When mains sometimes, bridge rectifier unit two exports high pressure, monitors after voltage regulation units through three ends, enters load The power end of unit, conversion and control audion is triggered by conversion and control resistance, therefore by the earth terminal of load unit, load current Through the colelctor electrode of conversion and control audion to emitter stage, because the grounded emitter line of conversion audion, therefore it is returned to Ground wire, is i.e. the earth terminal of bridge rectifier unit two.

When mains without time, bridge rectifier unit two is without output, and three ends monitoring voltage regulation units are without output, but now electric power storage Pond powers to load unit, and electric current is after load unit, through direct current conversion controllable silicon (in Fig. 1 13.1) to bridge rectifier list The earth terminal of unit one, is i.e. the negative terminal of accumulator, completes power supply.

Five, the principle explanation of automatic switch unit.

When mains sometimes, bridge rectifier unit two exports high pressure, and conversion and control audion (in Fig. 1 12.2) is touched Sending out, produce base flow, so conversion and control transistor collector has electric current, its current collection extremely saturation, its base loop is, bridge Formula rectification unit two positive pole, through control unit transistor base to ground, collector current loop is, three end monitoring voltage regulation units Output through load unit enter conversion and control audion colelctor electrode then arrive ground.Now direct current conversion controllable silicon is without triggering Voltage, that is to say no Anode current, for off-state.

When without mains, bridge rectifier unit two, does not produces without electricity without output, conversion and control resistance (in Fig. 1 12.1) Raw base flow, so conversion and control transistor collector no current, its current collection extremely cut-off state, and the voltage of accumulator is through negative After carrier unit, direct current transition trigger resistance (in Fig. 1 13.2) trigger direct current conversion controllable silicon (in Fig. 1 13.1), now Loop be that the anode of accumulator enters load unit through DC-isolation diode (in Fig. 1 9.1), then through overload list Enter direct current conversion silicon controlled anode after unit, direct current conversion silicon controlled negative electrode enter the ground connection of bridge rectifier unit one End, that is to say the negative pole of accumulator.

This utility model has a following significant advantage after implementing:

The quality of power supply, directly influences the performance of entirety.Power source performance is good, then overall performance is good.The one of particular importance It is that important equipment is generally equipped with Accessory Battery, as its scientific maintenance directly not affected the life of storage battery with reliable Property, it would be possible to become a kind of new trouble point, if if two is that the power supply parameter of supporting power supply is deposited with the power supply parameter of civil power Leading in difference, will directly affect electric property, three is that the automatic switchover performance needing two kinds of power supplys to be got well, to ensure each card signal Do not run off.Four is for ordinary electrical home appliance, and some important performances can make up with the behavior of employment, such as thundery sky, and can be artificial Pull out power supply, and a lot of equipment can not make up by artificial mode, such as the product of class of ensuring public security, pulls out power supply and just makes " security personnel " to become For blank, as being used in the equipment of signal transmission system, pull out power supply and can cause the unimpeded of system signal.What is more, sometimes people Also can not arbitrarily go to power-off source before equipment, pull out power supply.Details success, and the uncertain genus of the problems referred to above is thin Joint.This utility model is the regulated power supply that a kind of performance is the most excellent, and he has all excellent properties of current product, but also There is serial bright spot, therefore can be widely used for the needs of various electronic, the development that the adaptation electronic product moon new day is different Need.Concrete condition is as follows:

1, accumulator floating charge can remain to optimum state, because float charge voltage floating charge and load circuit are independent each other.Use Pulse charge form, has significant maintenance effects to accumulator, some critics claim that accumulator is filled bad rather than uses on the net Bad, and this measure can close the relative maximum scientific maintenance that charges of accumulator, and use such pulse charging manner, can not only The capacity making battery will not reduce with the life-span, even makes defective cell can obtain a certain degree of recovery, so meaning is the biggest 's.

2, Alternating Current Power Supply is separate with accumulator, is independent of each other, thus further increases reliability, two Shi Dangwu cities Automatically switching during electricity, accumulator automatically engages immediately, and when there being civil power, accumulator is excised automatically.Switch speed is fast, because of controllable silicon There is strong positive feedback, thus switch performance is good, load will not be produced impact.Ensure that the performance of load.Three is power saving, The way with relay is proposed in some technical data, but relay very power consumption, the most unfavorable to supporting accumulator.

3, overvoltage protection is good, and during protection, relay normally-closed contact disconnects, and rear class is formed protection quick-break, cuts off rear class, Rather than short circuit, so good effect, the stabilivolt connected due to protective relay is flexible, it is possible to formed required Anti-overvoltage grade.This lightning-arrest pipe being common is difficult to, because the lightning-arrest pipe of less than 100 volts is difficult to buy, and 50 volts Following anti-thunder tube is little to buy.This is very good to the most special electrical equipment, such as security personnel's equipment, does not results in unexpected thing Part (as thunderbolt) and damage, do not have security personnel's blank, in the amplifier of network loop, after will not going out thunderbolt, amplify yet The large-scale repair of device.

4, ac power supply circuit dependable performance, shows: A, source of stable pressure voltage regulation result are good.I.e. it is provided that stable voltage, Because this circuit is three end integrated stable voltage circuits, this circuit is a kind of outstanding mu balanced circuit, and its external piece is few, voltage regulation result Good, easy to use, low cost, and in this measure, contain again multiple protection, so being a kind of outstanding mu balanced circuit.

B, reliable operation, one be three-terminal voltage-stabilizing collector be the integrated stable voltage circuit of a kind of maturation, reliable operation.Two were The element of stream observation circuit is few, thus decreases the spoilage of element, so failure condition is few.

C matches with preposition protected location, further ensure that three ends will not damage.

D, possess the function of actively prompting, when equipment or power supply itself break down, when making electric current produce change, can lead Dynamic monitoring prompting, it is simple to people safeguard in time, is a kind of can monitor and can the outstanding power supply of voltage stabilizing.

5, the either voltage stabilizing in ac power supply system, or the DC power-supply system of accumulator, has the strongest adjustable Property, can extensively adapt to the needs of load.

6, simple in circuits, easily produces and debugging, and the debug point that reason one is because in circuit is few.Two are, the most easily quantify.Adjust Examination scope is loose, workable.

7, cheap, wide adaptability, matching is strong.
