Abstract:
An inverter circuit ( 120 ) is configured so as to perform synchronous rectification by six switching elements ( 130 ). The switching element ( 130 ) is formed of an unipolar device (SiC MOSFET in this case) using a wideband gap semiconductor. The inverter circuit ( 120 ) uses the body diode ( 131 ) of SiC MOSFET ( 130 ) as a freewheeling diode during synchronous rectification.

Claim (Index 1):
A power converter configured so as to perform synchronous rectification by a switching element, wherein\n the switching element is comprised of a unipolar device using a wideband gap semiconductor and including a body diode, the body diode of the unipolar device is used as a freewheeling diode, without the need of providing a separate external freewheeling diode connected in parallel to the unipolar device, the unipolar device turns on when a reverse current flows through the body diode used as the freewheeling diode, so that the reverse current flows through the unipolar device side to thereby perform synchronous rectification, power is converted from direct current to alternating current, or from alternating current to alternating current, the body diode turns on if a voltage is increased up to a predetermined amount or more when synchronous rectification is carried out, a turn-on voltage of the body diode is higher than an ON voltage of the unipolar device, and SiC is used as the wideband gap semiconductor.
