Background technology

Power supply is the key component of each electronic product, and the quality of power supply directly influences overall performance.Present product Product make rapid progress, and traditional power supply voltage regulation way has been not applied for the sci-tech product of modern innovation, and such as this enterprise once applied for Multiple products with regard to equipment of ensuring public security.The requirement to power supply for the product of these equipment is just very high, and overcritical degree will be significantly larger than commonly Household electrical appliances, are inefficient by traditional design.Reason is as follows：

One be power supply be often electrical equipment, the most troublesome keypoint part, all such to ordinary electrical home appliance.And to being furnished with electric power storage The product in pond is even more so, because during with accumulator, not only load power source, and increased the charging current filling accumulator again, If accumulator electricity consumption is excessive, initial charge stream is very big, thus more exacerbates the load of power supply, thus is easily damaged.

Two is the same day in thunderstorm season for the ordinary electrical home appliance, can pull out power supply prevention, needing the used time,（If desired for seeing electricity Apparent time）, because being easily alerted, can recover immediately, user is expected.And class product of ensuring public security is really highly difficult, because dialling Behind power down source, it is difficult intuitively to remind, because in the life of high rhythm, forgets about that these things are possible, now its protection function is just Failure, produces security personnel blank.If user is forgotten to recover, ensuring public security, it is blank to be in security personnel for a long time.And present stable state collection Become in lightning protection, very weak, such as generally input ceiling voltage is only 30 volts about.

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

Four is that security personnel's class product necessarily joins accumulator, and the maintenance of accumulator has higher requirement, wherein charging voltage Value is different with place value.If load request voltage stabilizing is pressed in voltage stabilizing, the requirement of charging can not be met, if by the voltage 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 are battery discharging system System, inevitable and mains-supplied system forms OR gate power supply mode to load, therefore both and the circuit being loaded with individual OR gate property. During battery discharging, most of time is every standard value saving 2 volts, and with discharging, this value also will decline, the therefore output of accumulator Voltage drop is of great value, if the pressure drop of the circuit of OR gate property is excessive.The normal standard of deviation then loading increases.Therefore adopt Any measure makes accumulator not produce excessive pressure drop in electric discharge, becomes difficult point.Difficult point three is to be to load when there being civil power Set of system, and no civil power when be that battery system is powered, conversion between the two is to automatically switch, therefore how could be real Now change scientific.Difficult point four is how to form two parts and power to be independent of each other each other, is 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 Go out and make to switch with relay, this scheme has multiple deficiencies, and the point of wherein one important deficiency is power consumption, difficult point six is, some Scheme cost is too high, is not suitable for the popularization 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 Further improve it is necessary first to be exactly power supply innovation, so it is perfect to need brand-new thinking that power supply is carried out.

First, this practical three-terminal voltage-stabilizing adjustment unit output voltage is flexibly adjustable.

Due to the Alternating Current Power Supply in this utility model, it is the main time to loaded work piece, be normal time, and power supply It is the part being easiest to damage.Devise two units for this in this measure, be that alternate current operation unit backs up list with exchanging Unit, alternate current operation circuit is by alternate current operation manostat（In Fig. 2 5.11）, resistance partially in alternate current operation voltage stabilizing（In Fig. 2 5.12）, resistance partially under alternate current operation voltage stabilizing（In Fig. 2 5.15）, pressure reduction diode（In Fig. 2 5.5）, alternate current operation voltage stabilizing adjust Whole diode（In Fig. 2 5.7）, exchange isolating diode one（In Fig. 2 5.13）Composition.Exchange fallback circuit is by exchanging backup Manostat（In Fig. 2 5.21）, partially resistance in exchange backup voltage stabilizing（In Fig. 2 5.22）, partially resistance under exchange backup voltage stabilizing（Figure In 2 5.25）, exchange isolating diode two（In Fig. 2 5.23）Composition.And take a kind of special design, this set Meter is in the connection to ground wire in the manostat in alternate current operation unit, increased a pressure reduction diode, so outfan A few pressure reduction diode to be held than the output of exchange backup units voltage stabilizing manostat；So work audion output voltage is high In the output of backup manostat, backup integrated stable voltage circuit will be sealed up a door, and no current exports, and power consumption is similar to zero, so backup Voltage stabilizing manostat will not damage, and is in a kind of Status of Backups.After the integrated device that works damages, backup is integrated will to export electricity automatically Pressure.

Secondly, adjust diode to employ the commutation diode of face combination in pressure reduction diode and voltage stabilizing in this part, that is, adopt With high-power voltage-stabilizing tube, it is in the state of low load with strong power, therefore this part is reliable.

Alternating Current Power Supply unit has excellent performance：One is output voltage stabilization, and two is to have overcurrent protection, and main cause is Employ three end integrated stable voltage circuits, this circuit has excellent performance.Three is inclined resistance and resistance shape inclined under voltage stabilizing in voltage stabilizing Become the trimming circuit of voltage stabilizing, the voltage of below 0.7V can have been adjusted, AC voltage-stabilizing adjustment diode becomes in voltage stabilizing have been adjusted, because One diode is 0.7V, so can be transferred to desirable value by voltage stabilizing output for aspect ground very much.

2nd, this utility model has the good explanation of overvoltage protection.

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 with protection quick-break, therefore has protective effect to thunderbolt, form a kind of special protection.This protection shape The principle becoming is that rear class is cut off, rather than short circuit, so good effect, in numerous equipment of many Compact Power Plants Lightning protection is it is simply that adopt this fast tripping protection.The stabilivolt connected by protective relay is flexibly it is possible to form institute The anti-overvoltage grade needing.The lightning-arrest pipe that this is common is difficult to, because less than 100 volts of lightning-arrest pipe is difficult to buy, and Less than 50 volts of anti-thunder tube almost can't buy.

The explanation of the 3rd, independent charge circuit feature, i.e. the explanation of floating charge unit.

Not being in high-grade pressure stabilizing device, it is difficult to ensure that there is the accumulator of floating charge and civil power is powered has height simultaneously The unification of degree.This measure employs special design, will be completely separable with load circuit for typically supporting floating charge loop, thus tool There is good advantage.Now taking load and need 12 volts as a example, if the accumulator of 12 volts of adapted.Then during accumulator floating charge, need 13.8 volts about, if not designing special circuit, when civil power has electricity, power output end is 13.8 volts about for a long time, and this is right Only need 12 volts of load unfavorable.If power end output adjustment is 12 volts, though load request can be met, but departing from accumulator Needed for floating charge 13.8 volts.Devise accumulator floating charge and discharge cell for this system.Its floating charge principle is that civil power has electricity When, bridge rectifier one output has electricity, through floating charge audion, then the ground connection returning to bridge rectifier one through accumulator End, is also the negative terminal of accumulator, thus forms floating charge independent loop, and according to kirschner law, and the experiment of circuit, this floating charge is returned Road is self-existent, with three-terminal voltage-stabilizing adjustment unit, the current supply circuit of load is not interfere with each other, three-terminal voltage-stabilizing adjustment unit pair The current supply circuit of load is the output current of bridge rectifier two, through three-terminal voltage-stabilizing adjustment unit to load, is then return to Ground wire, that is to say the earth terminal of bridge rectifier two.

When bridge rectifier one has output, stop filling the threshold value that door branch road forms accumulator, when accumulator When voltage is not up to this threshold value, switch N pipe does not start, the colelctor electrode no-voltage of switch P pipe, and now floating charge pipe fills to accumulator Electricity, when the voltage of accumulator exceeds this threshold value, switch N pipe is filled triggering, leads to the colelctor electrode output switching P pipe high-order, Thus closing floating charge pipe, accumulator stops charging, and now only trickle resistance provides, to accumulator, the trickle maintaining.

4th, civil power and accumulator duplicate supply explanation, its power supply trend is as shown in Figure 3.

When mains sometimes, Alternating Current Power Supply rectification exports high pressure, after the alternate current operation circuit, enters load unit Power end, conversion and control audion is triggered by conversion and control resistance, and therefore by the earth terminal of load unit, load current is through turning Change the colelctor electrode controlling audion to emitter stage, because the grounded emitter line of conversion audion, be therefore returned to ground wire, that is, It is the earth terminal of Alternating Current Power Supply rectification.

When mains no when, Alternating Current Power Supply rectification no exports, and alternate current operation circuit no exports, but now accumulator is to negative Carrier unit is powered, and electric current is after load unit, through direct current conversion controllable silicon（13.1 in Fig. 3）To bridge rectifier one Earth terminal, is the negative terminal of accumulator, completes to power.

5th, the principle explanation of automatic switch unit.

When mains sometimes, Alternating Current Power Supply rectification export high pressure, conversion and control audion（12.2 in Fig. 2）It is triggered, Produce base flow, so conversion and control transistor collector has electric current, its current collection extremely saturation, its base loop is to exchange Power-supply rectifying positive pole, through control unit transistor base to ground, collector current loop is, the output warp of alternate current operation circuit Overload unit enters the colelctor electrode of conversion and control audion and then arrives ground.Now direct current conversion controllable silicon no trigger voltage, It is no Anode current, be off-state.

When no mains, Alternating Current Power Supply rectification no exports, conversion and control resistance（12.1 in Fig. 2）No electricity, does not produce Base flow, so conversion and control transistor collector no current, its current collection extremely cut-off state, and the voltage of accumulator is through overload After unit, by direct current transition trigger resistance（In Fig. 2 13.2）Triggering direct current conversion controllable silicon（In Fig. 2 13.1）, now Loop is that the anode of accumulator is through DC-isolation diode（In Fig. 2 9.1）Enter load unit, then through load unit Enter direct current conversion silicon controlled anode afterwards, the earth terminal that silicon controlled negative electrode enters bridge rectifier one changed by direct current, That is to say the negative pole of accumulator.

This utility model has following significant advantage after implementing：

The quality of power supply, directly influences overall performance.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, such as can not directly affect the life of storage battery and reliability to its scientific maintenance Property it would be possible to become a kind of new trouble point, if two is if that the power supply parameter of supporting power supply is deposited with the power supply parameter of civil power Lead in difference, electric property will be directly affected, three is that the automatic switchover performance needing two kinds of power supplys will be got well, to ensure each card signal Do not run off.Four is for ordinary electrical home appliance, and some important performances can be made up with the behavior of employment, such as thundery sky, can be artificial Pull out power supply, and a lot of equipment can not be made up with artificial mode, the product of class of such as ensuring public security, and pulling out power supply just makes " security personnel " one-tenth For blank, such as 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 possibly 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 Section.This utility model is a kind of very excellent regulated power supply of performance, 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, adapt to the different development of the electronic product moon new day Need.Concrete condition is as follows：

1st, accumulator floating charge can remain to optimum state, because float charge voltage floating charge and load circuit are independent each other.

2nd, alternate current operation circuit and accumulator are separate, are independent of each other, thus further increase reliability, and two is to work as No civil power when automatically switch, accumulator automatically engages immediately, and when there being civil power, accumulator is excised automatically.Switch speed is fast, because can Control silicon has strong positive feedback, thus switch performance is good, will not produce impact to load.Ensure that the performance of load.Three is province Electricity, proposes the method with relay in some technical data, but relay very power consumption, to supporting accumulator very not Profit.

3rd, overvoltage protection is good, and during protection, relay normally-closed contact disconnects, and rear class is formed with protection quick-break, rear class is cut off, Rather than short circuit, so good effect, the stabilivolt connected by protective relay is flexibly it is possible to required for forming Anti- overvoltage grade.The lightning-arrest pipe that this is common is difficult to, because less than 100 volts of lightning-arrest pipe is difficult to buy, and 50 volts Following anti-thunder tube can hardly have been bought.This is very good to much special electrical equipment, such as security personnel's equipment, does not result in unexpected thing Part（As thunderbolt）And damage, be not in that security personnel are blank, in the amplifier of network loop, after also will not going out thunderbolt, amplify The large-scale repair of device.

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

5th, simple in circuits, easily produces and debugging, and the debug point that reason one is because in circuit is few.Two are, easily quantify very much.Adjust Examination scope is loose, workable.

6th, cheap, wide adaptability, matching is strong.
