Background technology

Power supply is the key of each electronic product, the quality of power supply directly affect entirety performance, electronic product day crescent Different, need the function of power supply also to tend to reach perfection and could meet the requirement of product, so there being the most outstanding regulated power supply at present. Although but the power supply of these voltage stabilizings has many good qualities, needs with rapid changepl. never-ending changes and improvements still can not be met.

Once multiple product about security personnel's equipment had been applied for such as this enterprise.The product of these equipment is to the requirement of power supply the most very Height, 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.

Possess the double loop Switching power of N-type constant-current charge, by DC rectifier unit, AC rectification unit, switch lightning protection Unit, AC voltage-stabilizing unit, load unit, accumulator, N-type constant-current charge unit, TCU transfer control unit, controllable silicon converting unit Collectively constitute.DC rectifier unit and AC rectification unit through or gate diode after common access switch lightning protection unit, use The rapid relay of response switchs, and when there being thunderbolt overvoltage, forms fast tripping protection, and accumulator employs the section of N-type constant current Huas charging modes, farthest ensure that the service life of accumulator, have employed the voltage stabilizing technique of maturation in AC voltage-stabilizing, The three-terminal voltage-stabilizing of i.e. 78 series, but add adjustable factor, accomplish steady while maintaining the number of advantages of three ends The adjustability of pressure, after connecting load unit, the TCU transfer control unit in automated conversion system when there being exchange, for connecting, is i.e. Form ac circuit, and controllable silicon converting unit now is for disconnecting, and is i.e. DC loop open circuit, during without exchange, conversion and control Unit is contactless, and voltage is disconnection, and controllable silicon converting unit is connected, and forms DC loop, and two loops do not interfere with each other, and automatically cut Change, thus this power supply has extensive and special purposes.

1, AC voltage-stabilizing has the strongest reliability.

AC voltage-stabilizing in this utility model have employed the three-terminal voltage-stabilizing technology of maturation, remains a series of of three-terminal voltage-stabilizing Advantage, adds in alternate current operation voltage stabilizing inclined resistance under inclined resistance, alternate current operation voltage stabilizing, and alternate current operation voltage stabilizing adjusts two poles Pipe, forms the adjustable of voltage, and its alternate current operation voltage stabilizing adjusts diode and uses heavy-duty diode, is in low load with strong power State, thereby ensure that this part reliability.

2, the present invention has the explanation that overvoltage protection is good.

There is good anti-overvoltage protection explanation: the stabilivolt that overvoltage protection 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 is little to buy.

Three, AC voltage-stabilizing unit has the explanation of excellent performance.

One is output voltage stabilization, and two is to have overcurrent protection, and main cause is to have employed three end integrated stable voltage circuits, this electricity There is the performance of excellence on road.In three AC voltage-stabilizing, inclined resistance defines the trimming circuit of voltage stabilizing, energy to inclined resistance with under AC voltage-stabilizing Adjusting the voltage of below 0.7V, AC voltage-stabilizing adjusts diode becomes tune in voltage stabilizing, because a diode is 0.7V, so Very aspect ground voltage stabilizing output can be transferred to desirable value.

The explanation of four, 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.Accumulator floating charge and discharge cell is devised for this native system.Its floating charge principle is that civil power has electricity Time, DC power supply unit rectification output has electricity, through N-type constant-current charge unit, then returns to DC rectifier unit through accumulator The ground terminal of bridge rectifier, be also the negative terminal of accumulator, thus form floating charge independent loop, according to kirschner law, and circuit Experiment, this floating charge loop is self-existent, does not interfere with each other the current supply circuit of load with AC voltage-stabilizing unit, and exchange is steady Pressure unit is the output electric current of bridge rectifier in AC rectification unit to the current supply circuit of load, through AC voltage-stabilizing unit to negative Carry, be then return to ground wire, that is to say the earth terminal of bridge rectifier in AC rectification unit.

1, the principle forming constant-current charge is.

The emitter stage of charging valve (in Fig. 1 8) connected constant current resistance (in Fig. 1 8.2), simultaneously base stage with connected Resistance end is connected to tuning instruction (in Fig. 1 8.5), plays metering function, when load current is excessive, and has exceeded tuning During the threshold value of instruction, base current will shunting, be no longer pass through audion and amplify, hereby it is ensured that emitter current is certain value, Thus become a kind of constant-current source.

Emitter stage be in series with constant current resistance is that adjustable resistance is connected with fixed resistance, and constant current can be carried out by adjustable resistance Adjusting, fixed resistance is that the minima to adjustable resistance is limited, thus ensure that constant current value is at a constrained sky Between.

It is that circuit is simplified by the benefit of such circuit, reliably, beneficially engineering, the most cost-effective.This external is humorous Adjusting instruction is to have light to indicate as a major reason of the current limiting device of constant current, and the constant current resistance connected when emitter stage is adjusted When trying correct, harmony instruction glimmers or relatively light, represents that debugging is correct.Because now constriction works.Generation constant current is imitated Really.Owing to the PN economize on electricity pressure of harmony instruction is about 1.2 volts, higher than 0.7 volt, so constant-current charge instrumentation tubes and constant current backup pipe Use one respectively.

2, the principle stopping to fill is: stop filling device (in Fig. 1 10.2) in-phase end stop filling in comparison inclined resistance (in Fig. 1 10.21) with stop filling compare under resistance (in Fig. 1 10.22) partially define and stop filling a threshold voltage of device in-phase end, work as electric power storage When pond (in Fig. 1 9) floating charge is to this threshold value, stops filling device output low level, stop filling diode (in Fig. 1 10.23) by charging valve Base stage clamper, make charging valve stop to accumulator charge, now by trickle resistance (in Fig. 1 7) to accumulator provide maintain Trickle.

Five, civil power and the explanation of accumulator duplicate supply, its power supply trend is as shown in Figure 2.

When mains sometimes, the bridge rectifier of AC rectification unit output high pressure, after AC voltage-stabilizing unit, enter The power end of load unit, conversion and control audion is triggered by conversion and control resistance, therefore by the earth terminal of load unit, load Electric current, because the grounded emitter line of conversion audion, returns the most again to emitter stage through the colelctor electrode of conversion and control audion Arrive ground wire, be i.e. the earth terminal of the bridge rectifier of AC rectification unit.

When mains without time, the bridge rectifier of AC rectification unit is without output, and AC voltage-stabilizing unit is without output, but now Accumulator is powered to load unit, and electric current is after load unit, whole through direct current conversion controllable silicon (in Fig. 2 13.1) to direct current The earth terminal of the bridge rectifier of stream unit, is i.e. the negative terminal of accumulator, completes power supply.

Six, the principle explanation of controllable silicon converting unit.

When mains sometimes, the bridge rectifier of AC rectification unit output high pressure, conversion and control audion is (in Fig. 1 12.2) it is triggered, produces base flow, so conversion and control transistor collector has electric current, its current collection extremely saturation, its base stage Loop is, AC voltage-stabilizing rectification positive pole, and through control unit transistor base to ground, collector current loop is, AC voltage-stabilizing Then the colelctor electrode that the output of unit enters conversion and control audion through load unit arrives ground.Now direct current conversion controllable silicon without Trigger voltage, that is to say no Anode current, for off-state.

When without mains, the bridge rectifier of AC rectification unit is without output, conversion and control resistance (in figure 12.1) nothing Electricity, does not produce base flow, so conversion and control transistor collector no current, its current collection extremely cut-off state, and the electricity of accumulator Pressure, after load unit, is triggered direct current conversion controllable silicon (in Fig. 2 by direct current transition trigger resistance (in Fig. 2 13.2) 13.1), loop now is, the anode of accumulator enters load unit through DC-isolation diode (in Fig. 2 9.1), then After load unit, enter direct current conversion silicon controlled anode, direct current conversion silicon controlled negative electrode enter DC rectifier unit The earth terminal of bridge rectifier, that is to say the negative pole of accumulator.

The present invention 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.The present invention 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 has Series bright spot, therefore can be widely used for the needs of various electronic, the development need that the adaptation electronic product moon new day is different. 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.In addition Use constant-current charge form, accumulator is had significant maintenance effects, some critics claim that accumulator is filled bad on the net, and not Damage, and this measure can close the relative maximum scientific maintenance that charges of accumulator, and use such charging modes, 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, AC voltage-stabilizing unit is separate with accumulator, is independent of each other, thus further increases reliability, and two is to work as In time without civil power, automatically switches, and accumulator automatically engages immediately, and when there being civil power, accumulator is excised automatically.Switch speed is fast, because of can Control silicon has strong positive feedback, thus switch performance is good, load will not be produced impact.Ensure that the performance of load.

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, 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.
