Latest generation White Band Gap (WBG) transistor technology make a truly bridgeless Power Factor Correction (PFC) topology a viable option. This presentation will highlight the key advantages of a totem pole pfc over other widely used pfc topologies and explains why GaN and SiC semiconductors make it attractive to consider it for new applications. This will be completed by a detailed loss analysis covering the different technologies and a reference design that could work as a starting point for your next application.
