Abstract :
This paper presents a performance analysis in steady-state of a novel type auxiliary resonant commutation snubber-linked 3-level 3-phase voltage source type soft switching inverter suitable and acceptable for high-power applications in comparison with resonant DC linked 3-level 3-phase voltage source type soft switching inverter proposed previously which can operate under a condition of zero voltage switching (ZVS). The digital control scheme of this inverter is presented. The steady-state performances of this inverter are illustrated and evaluated on the basis of the simulation results
