Evaluations of voltage-source soft-switching inverter with single auxiliary resonant snubber

A novel prototype of auxiliary resonant DC link (ARDCL) snubber is proposed . The paper also describes a three-phase space voltage vector modulated sin ewave soft-switching inverter using the proposed ARDCL snubber circuit. whi ch together with new voltage vector correction principle can produce high-p erformance output voltage waveforms. The output voltage waveforms obtained by the software processing of the inverter are able to achieve a high quali ty sinewave on the basis of the new correction principle. The effectiveness of the resonant DC link three-phase voltage source soft-switching inverter is proven from a practical point of view.
