Competitive Advantage
REF_3K3W_TP_SIC_TOLL is Infineon's bridgeless totem pole PFC system solution with up to 98.9% peak efficiency, 1U form factor and 80W/in³ power density.
The REF_3K3W_TP_SIC_TOLL evaluation board uses CoolSiC™ MOSFET 650V G1 and 600V CoolMOS™ MOSFET in TOLL package. The combination of CoolSiC™ and CoolMOS™ achieves high performance in a compact form factor.
The bridgeless topology is fully digitally controlled by an Infineon microcontroller from the XMC™ 1000 series. The board not only performs well in steady-state conditions during PFC operation, providing high efficiency and high quality input current, but also meets the requirements for power line disturbances and brownout hold-up time.
