The Transphorm TDTTP4000W066C-KIT is a 4kW bridge-less evaluation board that demonstrates the advantages of gallium nitride (GaN) FET technology.
This evaluation board offers improved performance and efficiency with GaN FETs in fast-switching leg and low-resistance MOSFETs in the slow-switching leg of the circuit.
The evaluation board is designed around the Transphorm TP65H035G4WS 650V GaN FET and Microchip Technology’s MA330048 digital power plug-in module (PIM) with dsPIC33CK digital signal controller to control the PFC powertrain.
The TDTTP4000W066C-KIT operates at an input voltage range of 85Vac to 265Vac, 47Hz to 63Hz, and requires an ambient temperature of less than 50 degrees Celsius.
The digital 4kW bridge-less totem-pole PFC code is based on an open-source design from Microchip Technology that provides access to existing firmware.
Applications for GaN FET technology include motor-drive inverters, photovoltaic (PV) inverters, and PFC power supplies.
