ST Webinar - MOSFET Performance: Traditional Silicon vs. SiC in Industrial Power Supplies

21 Jul 2020 - 19 Oct 2020

Online, On Demand

Traditional Silicon vs. SiC in Industrial Power Supplies

Presented by STMicroelectronics and EBV Elektronik


The presentation discusses the main driving factors defining the proper MOSFET selection for flyback converter applications. They are mainly conductive and switching losses and guarantee safe operating conditions for every operating point defined by application specification. Attendees will learn about circuit differences for different technologies in the presentation.

For the purpose of testing the complete example set of industrial SMPS was built. This board can be supplied by very wide input voltage range - from 100 VDC up to 1 kV or equivalent AC source. The maximum output power is set to 100 W.

The webinar includes real measurement results compared with the previous theoretical analysis. It details cases in which newer technologies like SiC or Si superjunction technology bring benefits and where the older solution can be considered keeping acceptable performance.

Key Takeaways

  • Discover the basic requirements defining the primary switch for an auxiliary industrial SMPS
  • Understand the critical performance features of MOSFETs applicable for single switch flyback converters operating at high input voltage
  • See a real performance comparison for different operating conditions
  • Understand the benefits of newer technologies and SMPS operating conditions when this benefit brings significant improvement
