STARTER-GENERATOR OF AUTOMOBILE Russian patent published in 2015 - IPC F02M11/04 

FIELD: electricity.

SUBSTANCE: starter-generator is provided with an angular rotation speed setting device, a comparison device, an angular rotor rotation speed meter, a proportional-integral angular speed control, the input of which is connected to the output of the comparison device, to the inputs of which signals are supplied from the angular rotation speed setting device and from the angular rotor rotation speed meter, and the output of the proportional-integral control of the angular speed is connected to an analogue input of a supervising controller, and outputs of the supervising controller are connected to inputs of switching transistors of a three-phase bridge inverter; at the starter-generator output there is a voltage stabiliser, the output of which is connected to a storage battery and to the load; besides, the proportional-integral control of angular speed is tuned for compensation of an equivalent mechanical time constant of the starter-generator at operation in a starter mode.

EFFECT: increasing service life of failure-free operation at simultaneous reduction of power consumption of a starter-generator.
