This reference design presents a 6.6-kW totem-pole(TTPL) bridgeless power factor correction (PFC)solution for Onboard Charger. The power stageimplements silicon carbide (SiC) MOSFETs driven bya C2000™ microcontroller (MCU) with SiC-isolatedgate drivers. The design implements three-phaseinterleaving and operates in continuous conductionmode (CCM) to achieve a 98.60% efficiency at a 240-V input voltage and 6.6-kW full power. The C2000controller enables phase shedding and adaptive deadtime

control to improve the power factor at light load.

The gate driver board (see TIDA-01605) implementsreinforced isolation and can withstand more than 100-V/ns common-mode transient immunity (CMTI). Thegate driver board also contains the two-level turnoffcircuit, which protects the MOSFET from voltage

overshoot during the short-circuit scenario.
