Magneto synchronous generator controlling system used for hybrid vehicle

Abstract

A magneto alternator control system for a hybrid vehicle comprises a rotor position detector (10), a phase current detector (20), an alternator electronic control unit (40) and a controllable rectifier (50). Wherein, the alternator electronic control unit (40) is composed of a signal receiving / sending module (41), a data processing module (42) and a control output module (43). The signal receiving / sending module (41) respectively receives a rotor position and angle signal, a phase current signal and an alternator control torque value T. In addition, the data processing module (42) calculates a pulse width modulation control waveform. The control output module (43) outputs the calculated pulse width modulation control waveform to the controllable rectifier (50). The controllable rectifier (50) is composed of a plurality of intelligent power modules and drive boards. The drive board controls switch-on sequence, switch-off time and switch-on time of these intelligent power modules according to the pulse width modulation control waveform.

Description

technical field [0001] The invention relates to a vehicle generator control system, in particular to a hybrid vehicle permanent magnet synchronous generator control system. Background technique [0002] A hybrid vehicle uses a traditional internal combustion engine and an electric motor as a power source, and drives the vehicle through a mixture of two systems of heat energy and electric energy. The biggest feature of the hybrid power system is the complementary working mode of oil and electric engines. When starting or driving at low speed, the vehicle is only driven by electricity, and the fuel consumption of the vehicle is zero at this time. When the vehicle's driving speed increases or urgent acceleration is required, the gasoline engine and electric motor start simultaneously and begin to output power. When the vehicle brakes, the hybrid system can convert kinetic energy into electrical energy, which is stored in the battery pack for use at the next low-speed driving....
