SYNCHRONOUS RECTIFICATION DEVICE AND SYNCHRONOUS ELECTRICAL MACHINE IMPLEMENTING SAME

摘要

The rectifier has four switches (21, 22, 31, 32) arranged on electrical connections of an H-bridge (10) and controlled by a programmable logic circuit (40). The switches connected in two pairs are in series with coils (5) of a synchronous electrical machine. Each switch has a number of parallel transistors controlled by the circuit. The number of transistors is determined from the power to be dissipated by each switch. An independent claim is also included for a multi-phase synchronous machine with a coil supplied by a direct current, under the control of a synchronous rectifier.
