资料介绍

This reference design presents a 6.6-kW totem-pole

(TTPL) bridgeless power factor correction (PFC)

solution for Onboard Charger. The power stage

implements silicon carbide (SiC) MOSFETs 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 98.60% efficiency at a 240-

V input voltage and 6.6-kW full power. The C2000

controller enables phase shedding and adaptive deadtime

control to improve the power factor at light load.

The gate driver board (see TIDA-01605) implements

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.
