Description
The utility model belongs to the automobile current generator electronic voltage regulator.
The automobile current generator electronic voltage regulator is made up of voltage detecting circuit, switching circuit and protective circuit at present.Its operation principle is to cooperate the exciting current of switching circuit with the control generator by voltage detecting circuit, comes the output voltage of stable generator.But also there are the following problems for this adjuster: because the input resistance of protective circuit is to be connected between load and the switching circuit, detect resistance and will consume certain power, therefore, reduced flowing into the electric current of giving dynamo field coil, made the corresponding decline of power output of generator; The 2nd, to stall, when ignition switch was in on-state, adjuster can not automatically shut down exciting current, and the temperature that makes magnet exciting coil that works long hours rises, and causes and burns; The 3rd, output voltage can not the segmentation adjustment, and this variation in the winter and summer temperature difference will influence storage battery to charging and discharging the requirement of voltage.
The purpose of this utility model be to provide a kind of perfect in shape and function, dependable performance, output voltage can adjust and protective circuit without the adjuster of power detection resistance.
The utility model adjuster adjusts circuit by voltage detecting circuit, switching circuit, protective circuit, automatic disconnection field circuit, output voltage and charging indication is formed.Its technical characterictic is to have improved protective circuit, increased automatic disconnection field circuit and output voltage and adjust circuit.Introduce the operation principle of the utility model adjuster below in conjunction with Fig. 2.
Protective circuit in the utility model adjuster is by resistance R

Embodiment:
The multi-function electronic adjuster is made up of output voltage adjustment circuit [1], voltage detecting circuit [2], switching circuit [3], protective circuit [4], automatic disconnection field circuit [5] and charging indication [6], sees Fig. 1.
In order specifically to introduce this circuit working principle, be illustrated below in conjunction with Fig. 2:
Work as ato unit, raise because of rotating speed at generator, when its output voltage surpassed setting, the voltage-stabiliser tube DW in the voltage detecting circuit punctured, the triode T in the switching circuit
1Conducting, T
2Carry and end, cut off as T
2The electric current of the dynamo field coil of load descends generator output voltage thereupon, and the decline of output voltage makes the voltage-stabiliser tube DW that has been in breakdown conditions recover again, then triode T
1Only carry triode T because of losing base current
2Again the electric current of dynamo field coil has been connected in conducting, and generator output voltage is risen once more.So go round and begin again, make adjuster play the output voltage of control and stable generator in prescribed limit.
