Webinar; Using silicon carbide FETs in a totem-pole design-in

Market news |
By Graham Prophet

The presentation will explore the use of the latest SiC MOSFETs in new low-inductance packaging to design a PFC system. When combined with a DC/DC circuit, the system can achieve system-level efficiency suitable for the 80+ Titanium standard [efficiency metric]. Attendees will learn the tradeoffs of using different switches and will see a review of a design that delivers a peak efficiency of over 98.5% and THD of less than 5%. This design features higher power density than existing silicon 80+ Platinum solutions and with higher efficiency, all at equivalent EBOM cost.


Wolfspeed’s Dr. Adam Barkley and Edgar Ayerbe will lead the webinar. Attendees will:


– Learn how to enable server and telecom power supplies to reach 80+ titanium efficiency requirements with no additional cost or complexity.

– Review a full reference design example of how to implement Totem Pole PFC using SiC MOSFETs.

– Understand the benefits of low-inductance discrete SiC MOSFET packaging and Kelvin-contact.

– See the latest SiC MOSFETs with low conduction losses, switching losses and Qrr, enabling new, simplified power conversion topologies.


For European engineers, the webinar is timed for end-of-day/early evening; 19:00 CET/ 6pm BST.
