Abstract :
A low-loss snubber circuit is presented that works in a 200 kVA GTO (gate-turn-off) inverter at a 540 V DC link and uses a self-oscillating DC-to-DC converter for energy recovery. Experimental results showing the simplicity, efficiency, and reliability of the device are reported. The DC-to-DC converter is investigated in detail.<>
