A novel test equipment for resonant circuits in high input voltage soft switching type DC-AC inverters and DC-DC converters

Recently, soft-switching techniques have been gradually introduced into DC-AC inverters and DC-DC power converters. The resonance phenomena generated by the inductor and capacitor are usually employed to achieve the soft-switching of main power switches and diodes in these power conversion circuits. In this paper, novel test equipment for resonant circuits is proposed and analysed, enabling the examination of the performance characteristics of the inductor and capacitor in high-voltage resonant circuits by using a relatively low voltage power supply.
