This paper presents a design methodology for an optimal DC-link RC snubber that can effectively suppress the parasitic ringing in high-speed, hard-switched converters with modern SiC MOSFETs. Unlike ...

IGCTs are connected in series for higher voltage applications. The paper takes ABB's 5SHY35l4510 IGCT as the research object. A RC-snubber circuit is designed for series-connected IGCTs. The values of ...
