By using the FET-Jet Calculator design tool, you can easily check the most appropriate devices for all of your power applications.

90-260VAC/400VDC PFC

The 90-260VAC – 400VDC Power Factor Correction Board is a hard switched single phase PFC. It is designed to demonstrate the efficiency of the UnitedSiC standard drive FETs and diode products for 80 Plus certified computer power supplies.

440Vac 800VDC Power Factor

Efficiency vs. Vin(AC)

The hard switched current average PFC is very viable in Gold rated 80 Plus supplies, and a plausible option for the higher efficiency Platinum and Titanium ratings.
