Abstract

In this paper, a novel circuit topology of the active auxiliary edge resonant snubber suitable for high power soft switching inverter applications which has some salient features as compared with conventional auxiliary resonant pole type snubber is proposed in order to minimize the switching power losses of power semiconductor devices (IGBTs) in addition to the switching surge related electromagnetic noises (EMI / RFI) 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 used as the battery energy storage system. This resonant snubber-assisted inverter topology suitable for high power conversion is described and discussed on the basis of soft switching transition and commutation operation of the voltage source type high efficient 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 resonant snubber. Furthermore, the three phase soft switching sinewave PWM inverter with the novel auxiliary active edge resonant bridge leg link snubbers treated here is evaluated and discussed as compared with three phase hard switching sinewave PWM inverter.
