The Experimental Consideration about Loss of Three-phase Voltage-fed inverter Resonant DC Link

ARDCL를 이용한 3상 전압형 인버터의 해석과 고성능화의 고찰

This paper deals with the power loss analysis of voltage source type space voltage vector modulated soft switching inverter, and proposed the new voltage vector correction principle during one sampling period on realize high quality cutput voltage waveforms for two soft-swiching approches. The operating pinciple of a single active auxiliary resonant DC link snubber circuit is described. Moreover, the effectiveness of soft switching inverter operating under the corrected voltage pattern is proved on the basis of simulation and experimental results.
