This paper presents of digitally-controlled 3-level 3-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 this soft switching inverter treated here which are suitable for high power utilization systems is illustrated and evaluated as compared with the 3-level 3-phase hard switching inverter on the basis of simulation and experimental results.
