Description
Technical field
Belong to electronic technology field.
Background technology
Power supply is the requisite part of electronic equipment, and any electronic equipment all needs power supply supporting with it.
Power supply also is the part of damaging easily, and one of its reason is that active of this part is among a kind of long operating state, and load is big, the 2nd, and when thunderbolt was arranged, its pressure of shoving at first acted on this element.
Because the reliability of power supply directly has influence on the global reliability of electronic equipment, so from certain meaning, judge the reliability Gao Bugao of this equipment, at first just should see its power supply reliability Gao Bugao.
And in the present electronic regulation source, generally having adopted with 78 series is the representative integrated circuit, and these integrated circuits have the following disadvantages as necessarily not innovating, the one, these integrated circuit inherencies exist the low weakness of input voltage, can not bear the pressure of gushing of thunderbolt.The 2nd, how to realize the backup relation, that is to say second integrated circuit how fill vacancies in the proper order by the science of carrying out, because can not adopt the method for two integrated circuit parallel connections to realize simply, will produce new problem like that after 78 serial integrated circuits damage.
Therefore how to improve the reliability of power supply, become problem one.
Summary of the invention
Task of the present invention and purpose are the technical schemes that proposes a kind of new power, the characteristics one of this power supply are that active among the present invention is not fragile when overvoltage not, the 2nd, namely be to damage inner active the energy realization science in back to fill vacancies in the proper order, realize normal power supply, also have multiple advantage simultaneously concurrently, thereby improve reliability and the performance of stabilized voltage power supply.
The measure that the present invention adopts is:
1, the balanced type power supply is by rectification unit, two symmetrical expression pressure regulation unit, and two symmetrical overcurrent protection display units, the voltage stabilizing value is adjusted branch road; Three overvoltage protection branch roads; Hybrid circuit is formed jointly.
Wherein: first pressure regulation unit is made up of a triode and peripheral element, be connected on the output of rectification unit with the collector electrode of triode, be connected between the base stage of collector electrode and base stage with a resistance, this pipe base stage has also connected following two-way: first branch road is that the voltage stabilizing value is adjusted branch road, second branch road is three overvoltage protection branch roads, and the 3rd branch road is the diode that has connected in overcurrent protection at the corresponding levels and the display unit; This pipe emitter has been connected becomes output at the corresponding levels behind the resistance in the overcurrent protection display unit at the corresponding levels.
Second pressure regulation unit is made up of another triode and peripheral element; this pipe collector and first module connect together; the base stage of this pipe base stage and first surge pipe connects together, and this pipe emitter has been connected becomes output at the corresponding levels behind the resistance in the overcurrent protection display unit at the corresponding levels.
First overcurrent protection is formed with the resistance that display unit is connected with emitter at the corresponding levels by a luminous tube, connects the base stage of triode in this unit with the positive pole of luminous tube, and the other end is connected on the output after the emitter series resistance at the corresponding levels.
Second overcurrent protection and display unit are made up of another luminous tube and another resistance, are connected on the base stage of triode in this unit with the positive pole of luminous tube, and the other end is connected on the output after the emitter series resistance at the corresponding levels.
It is that the surge pipe base stage has connected ground connection behind a voltage stabilizing didoe and the resistance that the voltage stabilizing value is adjusted branch road.
Three Overvoltage protecting units are ground connection after the surge pipe base stage has connected the voltage stabilizing branch road of voltage-stabiliser tube composition.
Hybrid circuit is made up of two diodes, and the positive pole of two diodes has been connected in the output of two triodes respectively, and negative pole connects together as last output of the present invention.
2, one of form of three overvoltage protections is the positive pole that the base stage of triode has connected a voltage stabilizing didoe, the minus earth of voltage-stabiliser tube; Two of form is positive poles that the base stage of triode has connected a voltage stabilizing didoe, the negative pole of the voltage-stabiliser tube ground connection behind several the diodes of having connected again.
3, the pressure regulation triode is high back-pressure large power triode, and diode is the face bonded type diode, and luminous tube is the high-brightness LED luminous tube.
Above measure is explained as follows:
One, the cardinal principle of voltage stabilizing:
Two pipes in the pressure regulation unit have adopted penetrating with output of balanced type, and very strong negative feedback is arranged, in case after line parameter circuit value is determined, adjust pipe and just can be stabilized on the concrete numerical value, and this precision can satisfy the needs of a lot of equipment.
Two, after the invention process, can produce the performance of multiple excellence, these performances one are that active of inside is not fragile; The 2nd, the reliability height, first pipe damaged when accident was arranged, and second pipe can provide normal power source; The 3rd, have overcurrent protection function, the 4th, can expand the civil power fluctuation range, increased the application space; The 5th, the overvoltage Presentation Function is arranged, expanded the function of source of stable pressure, the 6th, can adjust the output valve of voltage stabilizing flexibly, to adapt to the needs of floating charge.These functions all are very important for stabilized voltage power supply.
Three, inner active non-damageable reason when operate as normal;
1, when overvoltage not, when two pipes are worked simultaneously, can realize power science mean allocation.Its reason is the electric current that passes through when one of them pipe when excessive, and the resistance drop that emitter is connected increases, and the base current of this grade can reduce by the supporting diode passage of current protection, thereby has carried out modulation and balance automatically.
2, the unexpected overvoltage of thunderbolt and civil power is active flimsy main cause, and this circuit can be avoided well to both of these case.Its reason is as follows:
The first, adjust pipe and adopted high back-pressure high power valve, its back-pressure can reach hundreds of volts, almost is about 10 times of circuit of three-terminal voltage-stabilizing integrated input voltage of 78 series.
The second, increased anti-thunder tube and made second class protection, gushing of when thunderbolt can have been pressed to be limited within the triode back-pressure.
Three, being to have increased lightning protection three-level protective branch road, is three overvoltage protection branch roads.Exchange homogeneous tube base stage (also being power supply output) again and carry out strict pressure limiting.This part is among Fig. 1 shown in 106, is characterized in rectifier terminal when no overpressure situation, is adjusted branch road (107 place branch roads among Fig. 1) clamper by the voltage stabilizing value, does not have electric current to pass through, and equivalent electric circuit is open circuit.There is not electrical wear, can not damage.Thunderbolt is gushed and is pressed when excessive, and the voltage stabilizing value is adjusted the resistance that branch road goes here and there (among Fig. 1 108) both end voltage can instantaneous increasing, and causes this branch road conducting.Here it is very little to it should be noted that the voltage stabilizing value is adjusted the shared voltage ratio when operate as normal of resistance in the branch road, thus when operate as normal, do not influence normal pressure stabilization function basically, but when thunderbolt, play a good protection.
Three, when one of two pipes damage, another pipe can the realization science be filled vacancies in the proper order, thereby has improved reliability.Its reason: because the emitter of two pipes has all been gone here and there isolating diode, so when first pipe damages, can not increase the emitter load of second pipe, automatically formed open-circuit condition, as long as so adjust the resistance that transistor emitter is connected, unspoiled triode can normally outwards be powered, and does not influence overall performance.
Four, form the overcurrent protection principle: when output current is excessive; adjust the resistance drop increase that the pipe emitter is connected; when surpassing certain value; diode current flow in the overcurrent protection branch road; flow into output voltage and adjust the base current minimizing of pipe; the load overcurrent is super many, and then the base current of Jian Shaoing is more many, forms automatically to exchange the homogeneous tube protection.
Five, produce the reason of overcurrent protection indication: when forming overcurrent protection, base current is by light-emitting diode, and lamp is bright, and the LED light-emitting diode has played double action here, and the one, overcurrent protection kit, the 2nd, luminous indication.Advance it should be noted that together when debugging and should investigate into such situation, just often lamp does not work, and when fault was arranged, electric current was big and lamp is bright, and its benefit is to conclude whether fault is arranged by indicator light is whether shinny, namely being a kind of source of stable pressure thereby the present invention is become, also is a kind of monitor.
Six, can expand the surface analysis of civil power work:
1, the reason that can not damage circuit in the higher place of civil power and period: be high inverse-voltage tube because adjusting pipe, the voltage height of pipe bridge-type this moment output only, but also can be far below the high inverse-voltage tube withstand voltage.
2, can be in the main cause of the lower place of civil power and period work: the one, the triode in the circuit, can not produce the additional electrical pressure drop, directly the bridge rectifier output voltage is adjusted into the output voltage stabilizing circuit output voltage, namely be as long as bridge-type voltage is higher than output voltage, and this voltage can make triode work, just can voltage stabilizing.(illustrate: if the scheme that adopts traditional triode to connect with three end integrated circuits, because three ends will be stable work, voltage that must input is higher than definite value of output, if and the input prime of three end integrated circuits string has the triode reflector, then input has just increased the auxiliary voltage loss that emitter follower causes, that is to say when civil power is low, after bridge-type output must deduct supplementary loss voltage, be only the input effective voltage of three end integrated circuits.And when civil power was low, this was valuable voltage.), it two is to be high inverse-voltage tube because adjusting pipe, so can design the bridge-type output voltage higherly when design, when civil power was low, at this moment bridge-type voltage can not be very low, just can do certain compensation.
3, can expand the reason of civil power excursion: owing to last two reasons, do not damage circuit when civil power is high, and still can operate as normal when low.So can expand the working range that civil power changes widely.
Seven, can adjust the reason of different output voltage stabilizing values.Because in reference voltage first branch road, the pressure drop of voltage stabilizing didoe is leading role, so can form coarse adjustment, and the shared ratio of the resistance of connecting is very little, so also can make the usefulness of accurate adjustment, the benefit of accurate adjustment is can the furnishing normal voltage required to the storage battery floating charge, as 6,6 volts; 12,8 volts, etc., because float charge voltage all can be higher than normal discharge mark voltage.
Eight, after the employing measure 2, be conducive to produce in batches because debug more convenient, and precision height.Its reason is the voltage stabilizing value high conformity of second branch road, and only can many two PN joint than first branch road, both about 1,4 volt.
Following significant advantage is arranged after the invention process:
1, good reliability, its reason one are that its reliability is higher than common integrated circuit when home is used, and active is not fragile, and reason is analyzed as previously mentioned one by one, be not repeated.The 2nd, when one of therein pipe damaged, second pipe can be filled vacancies in the proper order, still can operate as normal.
2, performance is good, embodies in the following areas: the one, and lightning protection has multi-level protection, and is effective.At thunderstorm season, institute's adapted equipment is difficult for damaging, and can not quit work because of thundery sky.The 2nd, adapt to wide, can be in abominable period and district work.The 3rd, can be used for exporting the voltage stabilizing value that there is decimal in generation, be convenient to the floating charge of storage battery science is safeguarded.The 4th, excellent performance has over-voltage over-current protection.
3, have the overcurrent protection monitoring function, expanded the function of common integrated regulator, more convenient to the maintenance of electrical equipment.
4, the cost of the co-design of cost and traditional triode and three ends does not increase substantially, and cheap more a lot of than a lot of professional stabilized voltage power supplys.
5, adopted composite line, integral body is simplified, the reliability height, and be convenient to produce.
