Control circuit for e.g. alternator starter, has control circuit with configuration signal generating circuits for detecting functioning modes of electrical machine and for providing pulse width modulation, to control bridge

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.
