Auxiliary resonant DC Link and power loss analysis of three phase voltage type inverter

보조 공진 DC 링크 스너버형 컨버터와 3상 전압형 인버터의 전력손실분석

This paper proposes a new prototype auxiliary resonant DC link(ARDCL)snubber circuit and deals with its power loss on the basis of actually measured conduction loss characteristic of switching device module. Voltage type soft switching three phase inverter using proposed ARDCL snubber circuit is presented along with its performance evaluations. And, the power loss analysis of three phase hard and soft switching inverter are carried out from the point of simulation and experimental results.
