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

摘要

The circuit has a bridge (4) between continuous supply terminals, and sensors to measure current and/or voltage of phases of a stator. A rotation sensor and a detection circuit produce a signal representing position and rotational speed of a rotor. Configuration signal generating circuits (11, 13) of a control circuit (14) detect functioning modes of an electrical machine and provide pulse width modulation to control the bridge. An independent claim is also included for an electrical machine of a vehicle.
