ABSTRACT:
A pulse width modulation (PWM) control circuit for a multimode electrical machine and a multimode electrical machine equipped with such a control circuit, including a configuration circuit that detects the operation mode of the electrical machine and produces a pulse width modulation to control a reversible current inverter circuit such that the electrical machine operates optimally in torque in engine modes and in current generator modes. The invention applies to vehicle alternators and starters.
