Overview
The TDTTP4000W066C 4kW bridgeless totem-pole power factor correction (PFC) evaluation board (developed by Transphorm) achieves very high efficiency single-phase AC-DC conversion. Using 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 development board integrates Microchip's dsPIC33CK Digital Power PIM with Transphorm’s 4 kW AC-to-DC bridgeless totem pole power factor correction (PFC) evaluation board featuring SuperGaN™, the company’s latest Gen IV GaN technology.
The firmware can be downloaded from the software section below.
TDTTP4000W066C_0v1-KIT is for evaluation purposes only and is available from Transphorm.
