Feasible performance evaluations of active resonant snubber-assisted three phase soft switching inverter

This paper presents an active resonant snubber-assisted three phase voltage source type soft switching inverter with space voltage vector modulation scheme which can operate under the principle of zero voltage switching (ZVS) condition. The steady-state performances of this digitally-controlled soft switching inverter which is suitable for high-power applications is illustrated and evaluated as compared with a hard switching inverter on the basis of experimental results.
