Power conversion circuit

Abstract

A power conversion circuit includes a high side switching device connected at its collector to the high potential side of a power supply, a low side switching device connected at its emitter to the lowpotential side of the power supply, a first junction to which the emitter of the high side switching device and the collector of the low side switching device are connected, a first diode connected at its cathode to the collector of the high side switching device, a second diode connected at its anode to the emitter of the low side switching device, a second junction to which the anode of the first diode and the cathode of the second diode are connected, an inductance connected between the first and second junctions, and a snubber circuit connected to the first junction and adapted to absorb stored energy in the inductance when a freewheeling current flows.
