Technical field
Belong to electronic technology field.
Background technology
Power supply is the key component of each electronic product, the quality of power supply, directly influences the performance of entirety.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, as this enterprise once applied for
Multiple products about security personnel's equipment.The product of these equipment is the highest to the requirement of power supply, and overcritical degree will be significantly larger than common
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, 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.

It is further described below:
Main purpose of the present utility model is, utilizes ripe three-terminal voltage-stabilizing technology, increases regulatory function, makes AC voltage-stabilizing
Output is more accurate, uses New Measure, increases the DC loop of accumulator, solves charge and discharge contradiction during Accessory Battery, shape
Become direct current and share with exchanging, and form automatic switchover, so that this power supply has extensive and special purposes.
One, this practical Alternating Current Power Supply unit output voltage is the most adjustable.
Three-terminal voltage-stabilizing in regulated power supply is the voltage stabilizing technique of a kind of maturation, and the three terminal regulator in this measure is (in Fig. 1
5.11) have employed two regulating resistors and that is to say in AC voltage-stabilizing under inclined resistance (in Fig. 1 5.12) and AC voltage-stabilizing electricity partially
Resistance (in Fig. 1 5.13) is matched, forms the adjustment of output voltage, and three end integrated stable voltage circuit ground connection have terminated AC voltage-stabilizing
The most inclined resistance, outfan and ground connection terminated inclined resistance in AC voltage-stabilizing, it is thereby achieved that being adjusted flexibly of output voltage.
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.
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 branch road (in Fig. 1 10.5), 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 ground connection
Resistance (in Fig. 1 10.8), 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 one output has electricity, through floating charge audion, then returns to the ground connection of bridge rectifier one through accumulator
End, is also the negative terminal of accumulator, thus forms floating charge independent loop, according to kirschner law, and the experiment of circuit, this floating charge is returned
Road is self-existent, does not interfere with each other the current supply circuit of load with Alternating Current Power Supply unit, the confession to load of the Alternating Current Power Supply unit
Electricity loop is the output electric current of bridge rectifier two, through Alternating Current Power Supply unit to load, is then return to ground wire, that is to say bridge
The earth terminal of formula rectification circuit two.
When bridge rectifier 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, its power supply trend is as shown in Figure 2.
When mains sometimes, Alternating Current Power Supply rectification output high pressure, after the alternate current operation unit, enter 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
Changing and control the colelctor electrode of audion to emitter stage, because changing the grounded emitter line of audion, being therefore returned to ground wire, i.e.
It it is the earth terminal of Alternating Current Power Supply rectification.
When mains without time, Alternating Current Power Supply rectification is without output, and alternate current operation unit is without output, but now accumulator is to negative
Carrier unit is powered, and electric current is after load unit, through direct current conversion controllable silicon (in Fig. 2 13.1) to bridge rectifier one
Earth terminal, is i.e. the negative terminal of accumulator, completes power supply.
Five, the principle explanation of automatic switch unit.
When mains sometimes, Alternating Current Power Supply rectification output high pressure, conversion and control audion (in Fig. 1 12.2) is triggered,
Producing base flow, so conversion and control transistor collector has electric current, its current collection extremely saturation, its base loop is, exchange
Power-supply rectifying positive pole, through control unit transistor base to ground, collector current loop is, the output warp of alternate current operation unit
Overload unit enters the colelctor electrode of conversion and control audion and then arrives ground.Now direct current conversion controllable silicon is without trigger voltage, also
It is i.e. no Anode current, for off-state.
When without mains, Alternating Current Power Supply rectification, does not produces without electricity without output, conversion and control resistance (in Fig. 1 12.1)
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, direct current transition trigger resistance (in Fig. 1 13.2) trigger direct current conversion controllable silicon (in Fig. 1 13.1), now
Loop is, the anode of accumulator enters load unit through DC-isolation diode (in Fig. 1 9.1), then through load unit
Rear entrance direct current conversion silicon controlled anode, is entered the earth terminal of bridge rectifier one by direct current conversion silicon controlled negative electrode,
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, alternate current operation 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.Three is province
Electricity, proposes the way with relay in some technical data, but relay very power consumption, to supporting accumulator the most not
Profit.
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.
