Abstract
A power conversion device such as an inverter using as bridge arm elements self-extinguishing-type switching elements for converting D-C input power into A-C load power. Snubbers, each including a capacitor and a diode in series, are connected in parallel with the switching elements. A discharging circuit, having a diode is connected across the diodes of the snubbers, and a power source feedback circuit, including a current transformer, are employed to return the current discharged from the snubbers to the input power source, thereby enhancing conversion efficiency.
