Check out the 1-hour, on-demand webinar to learn how to implement the totem pole power factor correction (PFC) topology with digital inrush current control leveraging Silicon Carbide (SiC) MOSFETs and Silicon Controlled Rectifiers (SCRs).

Silicon Carbide MOSFETs combined with SCRs offer an effective solution that enables compact, efficient, and well-controlled power factor correction for applications including high power switched-mode power supplies (SMPS), EV charging stations, and motor drives.

The session will introduce you to this unique solution and provide you with an understanding of how the circuit works and how it performs under all operating conditions.

You will also discover a rich set of resources and design information that make developing a totem pole PFC with SiC MOSFETs fast and easy.

You will learn:

  • The fundamentals and implementation of the PFC totem pole topology with digital inrush current limiter (ICL)
  • About our STEVAL-DPSTPFC1 3.6 kW reference design and its application as a totem pole PFC with digital ICL
  • The resources in our development ecosystem to help engineers implement such a design as this
  • A preview of an upcoming 2.5 kW CCM totem pole PFC solution that uses GaN transistors
