The TDTTP4000W066B 4kW bridgeless totem-pole power factor correction (PFC) evaluation board 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 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 TP65H035WS, 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.
