Three-phase soft-switching inverter with coupled inductors, experimental results

This paper presents experimental results of the three-phase soft-switching inverter with coupled inductors that verify the control method influence on efficiency improvement. Different kinds of control methods were tested on the 6 kW experimental inverter. A short discussion on a few design methods of the resonant tank elements was made. Experimental results confirm that the advanced control algorithm and the proposed new design method of the resonant tank elements significantly increase the efficiency of this resonant inverter.
