2.2 KW High Efficiency (80+ Titanium) Bridgeless Totem-Pole PFC with SiC MOSFET

PFC control scheme is widely adopted for AC-DC power conversion applications. The main advantage of adding a PFC stage in an AC-DC power converter is to achieve better efficiency, low total harmonic distortion (THD), and better power factor (PF). Disadvantages of using traditional PFC design include high conduction losses in the fixed diode bridge, low power density, more components, and high cost. This whitepaper discusses 2.2 KW High Efficiency (80+ Titanium) Bridgeless Totem-Pole PFC with SiC MOSFET.
