N2 - In auxiliary resonant snubber inverter (ARSI), the main switches work at zero voltage switching (ZVS) condition and the auxiliary switches operate at zero current switching (ZCS) condition. This is different from working in hard-switching inverter. In this paper, the MOSFETs switching behavior in ARSI is analyzed. The model of MOSFETs considering the junction capacitors is built. The zero-voltage turn-on of main MOSFETs and zero-current turn-off of auxiliary MOSFETs eliminate the Miller plateau. Due to the resonant capacitors reducing the voltage rise rate, the Miller effect is attenuated in the turn-off transition period of main switches. The theory was validated in the experiment with an inverter prototype. The results show that effectiveness of the theoretical analysis.
