Transphorm TP65H035G4WS | Demoboard TDTTP4000W066C_0V2

4kW Digital Bridgeless Totem-pole PFC Evaluation Board

Overview

TopologyBoost Converter
Input voltage85-270 V
IC revision2.0

Description

This user guide describes the TDTTP4000W066C 4kW bridgeless totem-pole power factor correction (PFC) evaluation board. Very high efficiency single-phase AC-DC conversion is achieved with Transphorm’s latest Gen IV (SUPERGaNTM) TP65H035G4WS, a diode-free Gallium Nitride (GaN) FET bridge with low reverse-recovery charge. Using Transphorm GaN FETs in the fast-switching leg of the circuit and low-resistance MOSFETs in the slow-switching leg of the circuit results in improved performance and efficiency.
