  • REGULATION SYSTEM FOR A CONTROL CIRCUIT OF A ROTATING ELECTRICAL MACHINE
    Publication number: 20190363656
    Abstract: The invention relates to a regulation system for a control circuit of a rotary electrical machine with a rotor provided with a winding (208), the control circuit being provided with a transistor (205). The regulation system (1) is designed to comprise a signal converter (201) in order to convert an amplitude width modulation signal (PWM) into a reference signal (SREF) with cosinusoidal form parts, and a comparator (202) in order to establish the difference between the reference signal (SREF) and a transistor current (IT), in order to deduce an error signal (ERR) from which a control signal (COM) applied to a gate of the transistor is determined.
