Abstract
An inverter circuit () is configured so as to perform synchronous rectification by six switching elements (). The switching element () is formed of an unipolar device (SiC MOSFET in this case) using a wideband gap semiconductor. The inverter circuit () uses the body diode () of SiC MOSFET () as a freewheeling diode during synchronous rectification.
