Series resonant converter for switched reluctance motor drive

摘要

A resonant DC link converter which is specifically adapted for driving a switched reluctance motor (SRM) using low power (VA) rated switches, includes an input circuit providing a DC supply voltage, a resonating inductance (connected to the switched input circuit) for generating a resonating DC link current, and an output converter circuit synthesizing a multi-phase AC output signal to power a respective phase winding of the SRM. A controller switches the switch devices of the input circuit and output converter circuits in a predetermined sequence.
