PULSE WIDTH MODULATION CONTROL CIRCUIT FOR MULTI-MODE ELECTRICAL MACHINE AND MULTIMODE ELECTRICAL MACHINE PROVIDED WITH SUCH A CONTROL CIRCUIT

摘要

The invention relates to a pulse width modulation (PWM) control circuit for a multi-mode electrical machine and a multimode electrical machine provided with such a control circuit. A configuration circuit (11, 13) detects the mode of operation of the electrical machine (1) and produces a modulation of pulse width, for control of a reversible AC/DC converter (4), such that the electrical machine operates with optimal torque in motor mode and optimal current in generator mode. Of application to vehicle starter/alternators.
