In comparison with several zero-voltage transition (ZVT) inverter topologies, a double-PWM converter is presented using a simple ZVT topology. The rectifier and inverter of this double-PWM share a set of commutation circuit which can provide soft-switching for the power devices and the diodes. The commutation circuit consists of 1 auxiliary device, 6 resonant inductors, and 12 diodes. Its topology is simpler than the conventional auxiliary resonant converter, leading to low loss and easy control. The control strategy and resonant working modes are analyzed. Experimental results show good performance of the system.

“…Besides, there is no work considering the integration of different soft-switching techniques. However, researches have succeeded on the matter of developing integrated ZVT power converter topologies [8], [9]. The main goal of this work is the integration of soft-switching cells with different operation features aiming to take full advantage of the characteristic benefits of each soft-switching technique, which is an approach that the literature still lacks and for this reason is investigated herein.…”

This paper proposes a methodology to develop integrated auxiliary soft-switching cells for converters with multiple poles. The integrated cells obtained are a result of a combination of two cells from the same soft-switching technique or even of cells from different techniques, originating hybrid cells. The resulting cells present fewer components, are lighter and present smaller volume than the conventional ones.
