User Guide TDTTP4000W065AN 0V1: 4kW Analog Bridge-less Totem-pole PFC Evaluation Board Overview This user guide describes the TDTTP4000W065AN 0v1 4kW Analog Bridge-less totem-pole power factor correction (PFC) evaluation board. Very high efficiency single-phase AC-DC conversion is achieved with the 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.

Figure 1. TDTTP4000W065AN 0v1 4kW analog totem-pole PFC evaluation board Warning This EV demo board is intended to validate GaN FET technology and is for demonstration purposes only and no guarantees are made for standards compliance. There are areas of this evaluation board that have exposed access to hazardous high voltage levels. Implement caution to avoid contact with those voltages. Also note that the evaluation board may retain high voltage temporarily after input power has been removed. Exercise caution when handling. When testing converters on an evaluation board, ensure adequate cooling. Apply cooling air with a fan blowing across the converter or across a heat sink attached to the converter. Monitor the converter temperature to ensure it does not exceed the maximum rated per the datasheet specification. May 25, 2021 2021 Transphorm Inc.
