Parallel Resonant DC Link Inverter with Low-Loss Auxiliary Circuit
摘要
Abstract
A parallel resonant DC link inverter with low-loss auxiliary resonant circuit was proposed to improve efficiency of the inverter .Auxiliary resonant circuit was added to DC link of conventional inverter to make DC-bus voltage decreased to zero pe-riodically ,which realized zero-voltage operation of all switching devices in inverter .Auxiliary switching devices could also be turned on under zero-current and turned off under zero-voltage .In addition ,only one auxiliary switch was in auxiliary resonant circuit so that control strategy was simple ;auxiliary switch and resonant devices were all in parallel with DC-bus to reduce loss of auxiliary resonant circuit .The operation principle was analyzed .The equivalent circuits at different operation modes and conditions for realiza-tion of soft-switching were presented .A 5kW laboratory prototype had been built .Experimental results were demonstrated to confirm validity of soft-switching inverter presented .关键词
