A Lossless Snubber Circuit on Power Supply for Welding Machines' Output Rectification Diode

용접기용 전원장치의 출력정류부 다이오드의 무손실 스너버회로

This paper proposes a new lossless snubber circuit on power supply for welding machine's output rectification diode. To improve the common inverter control type power supplies' problems that energy loss and heating in the snubber circuit because the output capacity makes too big heat energy in the circuit when the output current of the inverter is rectified by the diode bridge circuit, which includes the snubber circuit. This paper suggested new snubber circuit have increased power factor and confidence of output by being regenerate thus lost energy to input node.
