VEHICLE GENERATOR VOLTAGE REGULATOR Russian patent published in 2020 - IPC H02P9/30 

FIELD: electrical engineering.

SUBSTANCE: invention relates to automotive electrical generators voltage regulation systems. Technical result is achieved in vehicle generator voltage regulator, comprising stabilitron, multivibrator, control switch in generator excitation winding circuit, stabilitron is connected between output of generator and negative contact, input to generator terminal, first transistor of multivibrator by collector is connected through first resistor to generator output, and base – with potentiometer, which through third resistor is connected to generator output, and through fourth resistor – with minus contact, second transistor by collector is connected through first resistor to generator output, and base – with potentiometer, third transistor by collector is connected through fifth resistor with generator output, base – with emitter of first transistor, and emitter – with minus contact, fourth transistor by collector is connected through sixth resistor with generator output, base – with emitter of second transistor, and emitter with negative contact, collector of third transistor is connected to emitter of second transistor through first capacitor, emitter of first transistor is connected to collector of fourth transistor through second capacitor, collector of the fourth transistor is connected through the seventh resistor to the gate of the key transistor, the excitation winding of the generator by one pole is connected to the generator output, second pole – with drain key transistor, source of key transistor is connected to negative terminal, gate of key transistor is connected to negative terminal through eighth resistor, poles of the excitation winding of the generator are connected to each other through a diode, the first and the second capacitors are selected taking into account the oscillation frequency of multivibrator 16…20 Hz. First and second capacitors can have capacitors of 2 mcF each.

EFFECT: technical result of proposed invention consists in providing protection against modes, in which there is battery discharge without subsequent charging for a long period of time with provision of desulphation of plates of accumulator, which has undergone incorrect operating modes.
