98.6% Efficiency, 6.6-kW Totem-Pole PFC Reference Design for HEV/EV Onboard Charger
Description
This reference design functions from a base of silicon carbide (SiC) MOSFETs that are driven by a C2000 microcontroller (MCU) with SiC-isolated gate drivers. The design implements three-phase interleaving and operates in continuous conduction mode (CCM) to achieve a 98.46% efficiency at a 240-V input voltage and 6.6-kW full power. The C2000 controller enables phase shedding and adaptive dead-time control to improve the power factor at light load. The gate driver board (see TIDA-01605) is capable of delivering a 4-A source and 6-A sink peak current. The gate driver board implements a reinforced isolation and can withstand more than 100-V/ns common-mode transient immunity (CMTI). The gate driver board also contains the two-level turnoff circuit, which protects the MOSFET from voltage overshoot during the short-circuit scenario.
Features
