This evaluation board is a system solution for a bridgeless totem-pole power factor corrector (PFC) with bidirectional power capability. The EVAL_3K3W_TP_PFC_SIC is enabled by Infineon’s CoolSiC™ and CoolMOS™ Superjunction power MOSFETs as well as isolated drivers and an XMC™ microcontroller. This bridgeless totem-pole PFC board is intended for applications that require high efficiency (≈99%) and high power density (72W/in3) such as high-end server and telecom. In addition, the bidirectional power flow capability allows this design to be used in battery chargers or battery formation applications.The totem-pole implemented in the EVAL_3K3W_TP_PFC_SIC board operates in continuous-conduction mode (CCM) in both rectifier (PFC) and inverter mode which also implements digital control on Infineon XMC™ 1000 series microcontroller.
