Transphorm 4kW Analog Bridgeless Totem-Pole PFC Board

Product Overview

Transphorm 4kW Analog Bridgeless Totem-Pole Power Factor Correction (PFC) Board (TDTTP4000W065AN) achieves very high efficiency single-phase AC-DC conversion using the TP65H035WSG4, a diode-free Gallium Nitride (GaN) FET bridge with low reverse-recovery charge. Using the 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.

The TP65H035G4WS MOSFET is a normally-off device that enables AC-DC bridgeless totem-pole PFC designs. The MOSFET features fast-switching leg and low-resistance Silicon MOSFETs in the slow-switching leg of the circuit. This TP65H035G4WS MOSFET device is designed with the latest Gen IV, SuperGaN™ technology.

The TDTTP4000W065AN board uses the bridgeless totem-pole power factor correction (PFC) topology with a traditional Texas Instruments UCC28180 analog controller. This pairing provides fast and easy access to the high power density made possible by GaN FETs without the need for firmware development required by DSP. This board operates from 85V to 265V AC input voltage range and 387V DC output voltage. The TDTTP4000W065AN board is ideally used in data center power supply and broad industrial power supply.
