SiC MOSFET, as a promising power semiconductor devices, has attracted attention from many laboratories and companies for its super performance in high temperature, high voltage and high frequency applications. To protect the devices from overvoltage induced by parasitic inductance in high frequency applications, snubber circuit is a must. In this paper, simulation of snubber circuit in a high frequency PWM inverter is invested, under different numbers of snubber circuit , parasitic parameters, different kinds of load and whether a SiC SBD exsits. Some useful conclusions are obtained to help design more perfect snubber circuit.

New Perspective

A 59-year-old woman was referred to the institution with burdens of idiopathic ventricular tachycardia (IVT). Electroanatomic mapping revealed a complex fractionated, high frequency potential with long duration preceding the QRS onset of the IVT. The real end point of ablation was the disappearance of the conduction block of Purkinje potential during the sinus rhythm besides the disappearance of the inducible tachycardia. Location of distal catheter was at the moderator band (MB) by transthoracic echocardiography (TTE). Only irrigated radiofrequency current was delivered at both insertions of the MB which can completely eliminate the IVT.
