Abstract
The utility model relates to an automatic electronic voltage stabilizer, which is used for the generator of motor vehicles. The utility model can convert variable voltage between 3V and 14.3V into a 12V DC voltage which can achieve the required constant voltage after being processed by a multiple-resonance oscillator, a compound power amplifier, a converter, an electronic switch and ordinary process of the electronic circuit of the utility model. The utility model can be used as a constant power supply of the power supply system of an automobile and a tractor, and is particularly suitable for vehicles without accumulators with regard to the non-electric initiation vehicles.
Description
The utility model relates to the autoelectrinic voltage stabilizer that a kind of motor generator is used.
Present various motor vehicles (automobile, tractor) electrical system is all done the voltage stabilizing or the current stabilization of the upper limit, its mode is: contact (FT61 mechanical type) is arranged, contactless (JFT106-electronic type) two kinds, their common feature is: when generator voltage surpasses or is lower than limit value, regulator action (adhesive, by) with the exciting curent of control generator, and reach the purpose of two limit formula voltage stabilizings.In fact, FT61, JFT106 type regulator, when being lower than 1200 rev/mins, generator speed can not generate electricity, though adopted the separate excitation mode when low speed (800 rev/mins), can keep charging, when storage battery energy is low, just be difficult to keep operate as normal; They are two years old, because engine speed is constantly to change, large-scale variation also can take place in corresponding generator voltage in fact, like this accumulator, other consumers and use (low speed driving) is all produced very big influence, and these characteristics show the most obvious on Dyn..People know that the load voltage under the perfect condition is not with the rotation speed change of generator.Not actual not accomplishing, although do not accomplish at generator itself, but can realize at external circuit.
To sum up explanation, existing motor vehicle voltage stabilizer exists following shortcoming:
1, generator lower limit ability to work is low excessively, and particularly when storage battery energy was low, generator did not have terminal voltage output.
2, the voltage that obtains on load and the accumulator is the voltage (because of generator does not have stable excitation) that changes between 6-14 volt (24 overhead generators lie prostrate at 6-24) forever.
3, this large-scale variation will cause: reduce by 30% the serviceable life of accumulator, and shorten 37% the serviceable life of various electrical appliances.
The purpose of this utility model provides the alternating current that a kind of direct current with the generator commutation output terminal becomes certain frequency, the processing of boosting then, become this galvanic close boxlike electronic regulator that closes through rectification again, make the generating function that constant DC voltage output be arranged in big rotation speed change.
The purpose of this utility model realizes by following technical measures:
It comprises multivibrator, and the hybrid power amplifier also comprises step transformer and the electronic switch that has stabilivolt, and its multivibrator is by T
1, T
2Pipe becomes the alternating signal that can send to the DC input voitage of underrange, and this signal has passed through by T for satisfying the bearing power requirement

Advantage of the present utility model and effect are:
1, output voltage stabilization; When the revolution of engine was lower than 300 rev/mins, voltage stabilizer also can guarantee the output of 12 volts or 24 volts.
2, start on the vehicle (baby tractor) at non-electricity, can cancel accumulator, and can guarantee the regulation illumination of light fixture.
3, because this voltage stabilizer has adopted transistor controls, switching speed is fast, the life-span long, high reliability features so have.
Description of drawings is as follows:
Accompanying drawing of the present utility model is circuit theory diagrams.
Below in conjunction with accompanying drawing the utility model is described further:
The DC voltage of generator output is carried power supply through A, B for inverter circuit at 2, when the moment that power supply adds, owing to multivibrator T
1, T
2The discreteness of two pipes must have a first conducting, supposes T
2Elder generation's conducting, so, T

2Charging is when being charged to 0.5 volt of T when above
1Conducting (T
2By), corresponding T

5Also conducting, B
1Have the square wave output of negative half period again.So repeatedly, at B
1secondaryly just have the output of continuous square wave.
Because generator output voltage fluctuation excessive (3-14.3 volt or 6-24 volt) is directed at B
1Induced voltage in corresponding variation.Work as B
1When induced electricity forces down, W
2, V
1All be in cut-off state, and V
2Conducting, J
2Adhesive is output as specified output.Work as B
1Induced voltage is higher than W
1Voltage breakdown the time, V
1Conducting (V
2By), J
1Adhesive, B
1Primary and secondary is done equivalent output.But the so just constant power supply of proof load.
During use the output terminal of motor generator is inserted A, B 2 points of voltage stabilizer, wherein A point connects negative pole, and B point connects positive pole, the output identification of voltage stabilizer be DC+ ,-, above-mentioned connection correctly after, this machine just can carry out the voltage stabilizing processing automatically.When the minimum voltage of generator output is 3 volts, can make its voltage that has 12 volts output, this moment, the rotating speed of engine was 350 rev/mins.Can guarantee also that when 14.3 volts of the ceiling voltages of generator output 12 volts voltage exports, the rotating speed of engine is 1500-2200 rev/min at this moment.
