Abstract

In this paper, a novel circuit topology of the active auxiliary edge resonant snubber suitable and acceptable for high power soft switching inverter and rectifier applications which includes some salient features as compared with conventional active auxiliary resonant commutation pole snubber is proposed newly. This resonant snubber circuit can minimize the switching power losses of power semiconductor devices (IGBTs), switching voltage and current surges, high frequency leakage currents to the heat sink in addition to the switching surge related electromagnetic noises in high power conversion conditioning and processing circuits on the basis of the voltage source type sinewave PWM inverter and voltage source sinewave PWM PFC converter as well as bi-directional PWM converter interfaced the battery energy storage system. This resonant snubber-assisted inverter and rectifier for high power conversion is described and discussed on the basis of soft switching transition and commutation operation of the voltage source type high efficiency pulse modulated inverter. The operation principle and operating characteristics of this active auxiliary snubber circuit are respectively described, together with the practical design procedure of this unique edge auxiliary snubber. Furthermore, the three-phase soft switching sinewave PWM inverter with the novel auxiliary active edge resonant bridge leg link snubbers treated here is implemented and discussed as compared with three phase hard switching sinewave PWM inverter, along with the practical evaluations bi-directional double converter for UPS system.
