3.6 kW Totem Pole PFC with SiC MOSFETs Evaluation Board
TPPFCSIC-EVK-301-qs
The TPPFCSIC-EVK-301 implements a single-phase AC/DC conversion stage in Totem Pole PFC topology. Key components are
ROHM's Gen. 4 SiC MOSFETs (SCT4045DR) as the main high-frequency switching elements, as well as the BM61S41 single-
channel isolated gate driver IC. In addition, SJ MOSFETs (R6076ENZ4) and the BM2P101EK-LB PWM controller IC for the aux-
iliary power supply, among other components from ROHM, were utilized to create a high-performance AC/DC circuit for single-
phase operation.

This quick start guide will help you understand the connection, operating instructions and important notices and warnings that
must be carefully reviewed prior to the use of the board (Figure 1). For further information please refer to the user guide (No.
