Abstract :
This paper presents of digitally-controlled three-level three-phase voltage-fed soft switching inverter with two auxiliary resonant DC link (ARDCL) snubbers which can operate under a condition of zero voltage switching (ZVS). Its operating principle and its related new instantaneous space vector allocation method are proposed and discussed. The feasible performances of the soft switching inverter treated here, which are suitable for high power utilization systems, are illustrated and evaluated as compared with a three-level three-phase hard switching inverter on the basis of simulation and experimental results
