Description
Technical field
The invention belongs to electronic technology fields.
Background technique
Source of stable pressure is the important component part of electronic product, performance it is excellent, be directly related to whole performance, so
There are many outstanding regulated power supply integrated circuits, such as 78 series, 79 series etc. at present.Although these above-mentioned integrated series have
Lot of advantages is not still able to satisfy needs with rapid changepl. never-ending changes and improvements.
As this enterprise had once applied for multiple products about security personnel's equipment.Requirement of the product of these equipment to power supply is just very
Height, it is inefficient by traditional design scheme that ordinary electrical home appliance will be significantly larger than by, which making excessive demands degree,.The reason is as follows that:
First is that power supply is often electric appliance, the keypoint part of most easy break-down is such to ordinary electrical home appliance.And to equipped with electric power storage
The product in pond is even more so, because not only having load power source, and increase the charging current for filling battery when having battery,
If battery electricity consumption is excessive, initial charge stream is very big, thus more exacerbates the load of power supply, thus is easily damaged.
Second is that ordinary electrical home appliance on the day of thunderstorm season, can pull out power supply prevention, the used time is being needed, (as needed to see electricity
Apparent time) because being easy to be alerted, can recover immediately, user expects.And class product of ensuring public security is really highly difficult, because dialling
Behind power down source, be not easy intuitively to remind because in the life of high rhythm, forget about these things be it is possible, its protection function is just at this time
Failure generates security personnel's blank.If user forgets to restore, ensuring public security for a long time will be in security personnel's blank.And present stable state collection
At in lightning protection, very weak, such as generally input terminal ceiling voltage is only 30 volts or so.
Third is that because of the particularity importance of the product of security personnel, it is therefore necessary to adapt to power grid variation in design Shi Yaoyou
Wider, key benefit reason will not originally penetrate integrated regulator and damage first is that when voltage ripple of power network.Reason
Second is that the normal pressure stabilizing of energy when alternating current is relatively low or relatively high, not will cause the failure of protection function.Reason third is that, make to ensure public security
Product can have bigger use space.
Fourth is that security personnel's class product necessarily matches battery, and the maintenance of battery has higher requirement, wherein charging voltage
It is worth different with place value.If load requirement pressure stabilizing is pressed in pressure stabilizing, it is not able to satisfy the requirement of charging, if by the voltage of charging
As requiring, then load will be higher than for a long time it is normal needed for voltage.This is difficult point one.Difficult point is second is that if there is electric power storage tank discharge system
System, necessarily with mains-supplied system to load formation or door power supply mode, therefore the two and load have a or door property circuit.
Most of time is the standard value of 2 volts of every section when electric power storage tank discharge, and with discharging, the value will also decline, therefore the output of battery
Voltage drop is of great value, if or door property circuit pressure drop it is excessive.The normal standard of the deviation then loaded increases.Therefore it uses
Any measure makes battery not generate excessive pressure drop in electric discharge, becomes difficult point.Difficult point third is that be to load when there is alternating current
Set of system, and without alternating current when is battery system power supply, conversion between the two are to automatically switch, therefore how could be real
It now converts scientific.Difficult point is independent of each other each other fourth is that how to form two parts power supply, is when battery breaks down, no
It will affect mains-supplied system, otherwise will not influence battery system when mains-supplied system failure.Difficult point five, some data mention
Made to switch with relay out, this scheme is there are many insufficient, wherein the point of an important deficiency is power consumption, difficult point sixth is that, it is some
Scheme cost is excessively high, is not suitable for the universal of product.

3, direct current is converted silicon-controlled into one-way SCR.
4, pressure difference diode uses rectifier diode in conjunction with face with alternate current operation pressure stabilizing adjustment diode.
5, conversion and control triode uses large power triode.
It is further described below:
One, Alternating Current Power Supply has very strong reliability.
Due to the Alternating Current Power Supply in the present invention, it is the main time to loaded work piece, is normal time, and power supply is most
The part being easily damaged.Two units are devised in this measure thus, are alternate current operation unit and exchange backup units, and
And a kind of special design is taken, this design is the connection to ground wire in the integrated regulator in alternate current operation unit
In, a pressure difference diode is increased, so output end holds few one than exchanging the output of backup units integrated regulator
A pressure difference diode；So work triode output voltage is higher than the output of backup integrated circuit, backup integrated stable voltage circuit will
It is sealed up a door, no current output, power consumption is similar to zero, so backup integrated regulator will not damage, is in a kind of Status of Backups.
After the integrated device that works sleeps damage, backup is integrated by automatic position output voltage.
Secondly, adjusting diode to use the rectifier diode that face combines in pressure difference diode and pressure 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.
Two, the explanation that the present invention has overvoltage protection good.
Illustrate with good anti-overvoltage protection: the concatenated voltage-stabiliser tube of overvoltage protection relay institute suctions through, and corresponds to normally closed
Contact disconnects, and forms protection quick-break to rear class, therefore have protective effect to lightning stroke, forms a kind of special protection.This protection shape
At principle be to be cut off to rear class, rather than it is short-circuit, so good effect, in numerous equipment of many Compact Power Plants
Lightning protection is exactly using this fast tripping protection.Since the concatenated voltage-stabiliser tube of protective relay institute is flexible, it is possible to form institute
The anti-over-voltage grade needed.This is that common lightning-arrest pipe is difficult to realize, because 100 volts of lightning-arrest pipes below are difficult to buy, and
50 volts of anti-thunder tubes below can hardly be bought.
Three, alternate current operation unit has the explanation of excellent performance.
First is that output voltage stabilization, second is that there is overcurrent protection, main cause is to use three end integrated stable voltage circuits, the electricity
There is excellent performance on road.Three devise in pressure stabilizing and adjust, with pressure stabilizing trimming circuit, it is possible to which very aspect ground, which exports pressure stabilizing, adjusts
To desirable value.
Four, the explanation of independent charge circuit feature.
It is not in high-grade pressure stabilizing device, it is difficult to ensure that the battery with floating charge has height with what alternating current was powered simultaneously
The unification of degree.This measure uses special design, and general matched floating charge circuit and load circuit is completely separable, thus has
Have the advantages that fine.Now by taking load needs 12 volts as an example, if 12 volts of adapted of battery.Then when battery floating charge, need
13.8 volts or so, if not designing special route, when alternating current has electricity, power output end is 13.8 volts or so for a long time, this is right
Only need 12 volts of load unfavorable.If power end output adjustment is 12 volts, though it is able to satisfy load requirement, but departing from battery
13.8 volts needed for floating charge.This system devises battery floating charge and discharge cell thus.Its floating charge principle is that alternating current has electricity
When, the output of DC rectifier unit has electricity, and by pulse charge unit, the ground wire of DC rectifier unit is returned to using battery
The negative terminal of end and battery, thus floating charge independent loop is formed, according to the experiment of kirschner law and circuit, this floating charge is returned
Road be it is self-existent, do not interfere with each other with current supply circuit of the alternate current operation unit to load, confession of the alternate current operation unit to load
Electrical circuit is the output electric current of AC rectification unit, by alternate current operation unit to load, is then return to ground wire, that is to say exchange
The ground terminal of rectification unit.
When floating charge failure of oscillation device (10.2 in Fig. 2) output is low level, floating charge triode (8 in Fig. 2) conducting starts to storage
Battery charging, and when floating charge failure of oscillation device (10.2 in Fig. 2) are high-order, floating charge triode cut-off, battery stops charging, this
When from trickle resistance (7 in Fig. 2) to battery provide maintain trickle.
The negative of floating charge failure of oscillation device (10.2 in Fig. 2) be terminated with failure of oscillation compare upper inclined resistance (10.21 in Fig. 2) with
Failure of oscillation compares the threshold voltage that lower inclined resistance forms floating charge failure of oscillation device negative phase end, and principle is, when battery floating charge to this threshold
When value, floating charge failure of oscillation device exports high pressure, allows the floating charge blocking of oscillator by failure of oscillation isolating diode (10.23 in Fig. 2), floating charge
Oscillator output is high-order, stops charging to battery.
Five, the explanation of alternating current and battery duplicate supply, power supply trend are as shown in Figure 3.
When mains sometimes, AC rectification unit export high pressure, after alternate current operation unit, into load unit
Power end, conversion and control resistance trigger conversion and control triode, therefore by the ground terminal of load unit, load current is by turning
The collector of control triode is changed to emitter, because the emitter ground line of conversion triode, has been returned to ground wire, i.e.,
It is the ground terminal of AC rectification unit.
When mains without when, AC rectification unit without output, alternate current operation unit without output, but at this time battery to negative
Carrier unit power supply, electric current convert silicon-controlled (13.1 in Fig. 3) connecing to DC rectifier unit after load unit, by direct current
Ground terminal is the negative terminal of battery, completes power supply.
Six, the principle explanation of silicon-controlled converting unit.
When mains sometimes, AC rectification unit exports high pressure, and conversion and control triode (12.2 in Fig. 2) is triggered,
Base flow is generated, so conversion and control transistor collector has electric current, current collection extremely saturation state, base loop is to exchange
Rectification unit anode, by control unit transistor base to ground, collector current circuit is the output warp of alternate current operation unit
Overload unit enters the collector of conversion and control triode and then arrives ground.Direct current converts silicon-controlled no trigger voltage at this time,
It is no Anode current, is off-state.
When no mains, AC rectification unit does not generate base without electricity without output, conversion and control resistance (12.1 in figure)
Stream, so conversion and control transistor collector no current, current collection extremely off state, and the voltage of battery is through overload list
After member, silicon-controlled (13.2 in Fig. 2) are converted by direct current transition trigger resistance (13.1 in Fig. 2) triggering direct current, time at this time
The anode of Lu Shi, battery enter load unit by DC isolation diode (9.1 in Fig. 2), after load unit
Silicon-controlled anode is converted into direct current, and the ground terminal that silicon-controlled cathode enters DC rectifier unit is converted by direct current, namely
It is the cathode of battery.
The present invention has the advantages that following significant after implementing:
The quality of power supply directly influences whole performance.Power source performance is good, then overall performance is good.Especially important one
It is that important equipment is generally equipped with Accessory Battery, cannot such as directly affects the life of storage battery and reliable to its scientific maintenance
Property, it would be possible to as a kind of new fault point, if if second is that the power supply parameter of mating power supply and the power supply parameter of alternating current are deposited
It is led in difference, electric property will be directly affected, third is that needing the automatic switchover performance of two kinds of power supplys will get well, to guarantee each card signal
It is not lost.Fourth is that for ordinary electrical home appliance, some important performances can be made up with the behavior of employment, can be taking human as such as thundery sky
Ground pulls out power supply, and many equipment cannot be made up with artificial mode, the product for class of such as ensuring public security, pull out power supply just make " to ensure public security " at
For blank, the equipment for being such as used in signal transmission system, the unimpeded of system signal can be caused by pulling out power supply.What is more, sometimes people
Source is powered off before can not also arbitrarily going to equipment, pulls out power supply.Details success, and the uncertain category of the above problem is thin
Section.The present invention is a kind of regulated power supply that performance is very excellent, he has all excellent properties of current product, but also has
Serial bright spot, therefore can be widely used for the needs of various electronic adapts to the electronic product moon new day different development need.
Concrete condition is as follows:
1, battery floating charge is able to maintain optimum state, because float charge voltage floating charge and load circuit are independent each other.In addition
Using pulse charge form, have significant maintenance effects to battery, on the net some critics claim battery be filled it is bad, without
It damages, and this measure can close the opposite maximum scientific maintenance of charging of battery, and with such pulse charging manner, no
It is only capable of reducing the capacity of battery will not with the service life, or even defective cell is enable to obtain a degree of recovery, so meaning is
It is very big.
2, alternate current operation unit and battery are mutually indepedent, are independent of each other, thus further improve reliability, second is that working as
Automatically switch when no alternating current, battery automatically engages immediately, and when there is alternating current, battery is cut off automatically.Switch speed is fast, because can
Control silicon has strong positive feedback, thus switch performance is good, will not have an impact to load.It ensure that the performance of load.Third is that saving
Electricity, proposes the method with relay in some technical data, but relay very power consumption, very not to matched battery
Benefit.
3, overvoltage protection is good, and relay normally closed contact disconnects when protection, forms protection quick-break to rear class, cuts off to rear class,
Rather than it is short-circuit, so good effect, since the concatenated voltage-stabiliser tube of protective relay institute is flexible, it is possible to required for formation
Anti- over-voltage grade.This is that common lightning-arrest pipe is difficult to realize, because 100 volts of lightning-arrest pipes below are difficult to buy, and 50 volts
Anti-thunder tube below can hardly be bought.This is very good to many special electric appliances, and equipment of such as ensuring public security not will cause unexpected thing
Part (as be struck by lightning) and damage, be not in security personnel's blank, in the amplifier of network loop, will not go out after being struck by lightning, amplify
The large-scale repair of device.
4, two-stage output voltage (floating charge output voltage, with load output voltage) adjustability is strong, can adapt to load extensively
It needs.
5, simple in circuits, easy to produce and debugging, reason is first is that because the debug point in route is few.Second is that very easily quantization.It adjusts
It is loose to try range, strong operability.
6, cheap, wide adaptability, matching is strong.
