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.

1, exchange is automatically adjusted the characteristic of voltage regulation unit.

This unit is by voltage-reg-ulator tube (in Fig. 1 5.1), altemating trigger resistance (in Fig. 1 5.2), commissure resistance (Fig. 1 In 5.3), voltage-reference diode (in Fig. 1 5.5), amplifier tube (in Fig. 1 5.6), potentiometer (in Fig. 1 5.7), upper inclined point Inclined resistance (in Fig. 1 5.10) on piezoresistance (in Fig. 1 5.8), lower inclined divider resistance (in Fig. 1 5.9), benchmark, exchange every Form from diode (in Fig. 1 5.12):

It forms the principle being automatically adjusted: voltage-reg-ulator tube and amplifier tube together form mu balanced circuit accurately, former Because being that the base voltage of amplifier tube is a definite value, be i.e. emitter voltage add 0.7V(because the base voltage of audion all the time More 0.7V than emitter voltage), and lower inclined divider resistance, potentiometer, upper inclined divider resistance is connected jointly becomes a dividing potential drop electricity Road, if the output voltage of voltage-reg-ulator tube is too high, then the base current of amplifier tube is the biggest, thus amplifier tube collector current is just Greatly, the base current of voltage-reg-ulator tube is shunted the biggest, thus the output voltage of voltage-reg-ulator tube is reduced by, whereas if Output voltage is too low, and the base current of amplifier tube reduces, and amplifier tube collector current reduces, and the base current of voltage-reg-ulator tube increases Adding, so output voltage just improves, therefore defining adjustment automatically, so after potentiometer reaches required design load, making In with, the overtension or too low of voltage-reg-ulator tube output, can be formed and be automatically adjusted, add the reliability of voltage stabilizing.

In this unit, do not use 78 conventional series, and voltage-reg-ulator tube all uses with amplifier tube high back-pressure high-power Audion, topmost benefit is, audion high back-pressure, and far beyond the technical specification of 78 series only 30 volts, lightning protection effect is good. Also there is the feature that voltage regulation result is good simultaneously.Thus improve the reliable life of power supply source.

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.

Audion during this is practical is large power triode entirely, and back-pressure value is higher than 200V, so overvoltage capabilities is strong, is difficult to Damage.

The explanation of three, independent charge circuit feature, the i.e. explanation of floating charge unit.

By trickle resistance (in Fig. 1 7), floating charge pipe (in Fig. 1 8), stop filling door stabilivolt (in Fig. 1 10.4), stopping Fill adjustment diode (in Fig. 1 10.5), stop filling triggering resistance (in Fig. 1 10.6), switch N pipe collector resistance (in Fig. 1 10.3), switch N pipe (in Fig. 1 10.1), switch P manage (in Fig. 1 10.2), stop filling guiding resistance (in Fig. 1 10.8), stopping Fill earth resistance (in Fig. 1 10.9), stop filling steering diode (in Fig. 1 10.7), DC-isolation diode (in Fig. 1 9.1) composition.

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.Accumulator floating charge and discharge cell is devised for this native system.Its floating charge principle is that civil power has electricity Time, bridge rectifier unit one output has electricity, through floating charge pipe, then returns to the earth terminal of bridge rectifier unit one through accumulator, Also it is the negative terminal of accumulator, thus forms floating charge independent loop, according to kirschner law, and the experiment of circuit, this floating charge loop It is self-existent, with ac power supply circuit, the current supply circuit of load is not interfere with each other, the ac power supply circuit power supply to load Loop is the output electric current of bridge rectifier unit two, through being automatically adjusted voltage regulation unit to load, be then return to ground wire, that is to say The earth terminal of bridge rectifier unit two.

When bridge rectifier unit one has output, stop filling door branch road and form a threshold value of accumulator, when accumulator When voltage is not up to this threshold value, switch N pipe does not starts, and the colelctor electrode no-voltage of switch P pipe, now floating charge pipe fills to accumulator Electricity, when the voltage of accumulator exceeds this threshold value, switch N pipe is filled triggering, causes the colelctor electrode output high position switching P pipe, Thus close floating charge pipe, accumulator stops charging, the most only trickle resistance provides the trickle maintained to accumulator.

Four, civil power and accumulator duplicate supply explanation.

When mains sometimes, bridge rectifier unit two exports high pressure, after being automatically adjusted voltage regulation unit, enter 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, without output, is automatically adjusted voltage regulation unit without output, but now electric power storage Pond powers to load unit, and electric current is after load unit, through direct current conversion audion (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 to be automatically adjusted voltage regulation unit Output through load unit enter conversion and control audion colelctor electrode then arrive ground.Now direct current conversion audion is without triggering Voltage, that is to say without collector 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 audion (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 the colelctor electrode of direct current conversion audion after unit, the emitter stage of direct current conversion audion enter connecing of bridge rectifier unit one Ground 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.

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 audion There is strong positive feedback, thus switch performance is good, load will not be produced impact.Ensure that the performance of load.

3, excellent performance, one is that anti-thunder is especially good with overvoltage protection effect, and during protection, relay normally-closed contact disconnects, to rear Level forms protection quick-break, cuts off rear class rather than short circuit, so good effect, and voltage-reg-ulator tube is the big merit of high back-pressure Rate audion, its back-pressure value >=200V.Three is that voltage regulation result is good, because being automatically adjusted of voltage can be formed, it is ensured that voltage stabilizing Effect.Having broader adaptation ability than traditional regulated power supply, occurring, unexpected voltage is high, will not damage.And it is relatively low at voltage Place also can normally work with the period.

4, two-stage output voltage (floating charge output voltage, with load output voltage) adjustability is strong, can extensively adapt to load Need.

5, 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.

6, cheap, wide adaptability, matching is strong.
