Watch the one-hour on-demand webinar to learn the basics of silicon carbide (SiC) MOSFET technology and how it is transforming performance in switched-mode power supplies.

The session will start with a focus on one of the most important blocks of many power converters, Power Factor Correction (PFC), supplementing the discussion with the results of performance testing in a bi-directional DC-DC converter. Next, we'll explore two bridgeless PFC topologies, the Vienna rectifier and totem-pole PFC.

We will demonstrate via experimental results and application examples how using silicon carbide increases efficiency and improves thermal performance in bi-directional DC-DC conversion. To conclude, you will be shown how to jumpstart development with SiC MOSFETs using our range of design resources and reference designs.

The on-demand webinar will cover:

  • The fundamentals of silicon carbide as a wide bandgap semiconductor
  • An introduction to PFC followed by a deep dive into bridgeless PFC topologies
  • Application examples and ST reference designs available for Vienna rectifier, totem-pole PFC, and bi-directional DC-DC power stages
  • The resources in our development ecosystem to help engineers design with SiC MOSFETs
