TDTTP4000W066B-KIT: 4kW Bridgeless Totem-pole PFC Evaluation Board

Summary

TDTTP4000W066B - KIT is a 4kW bridgeless totem-pole power factor correction (PFC) evaluation board. Very high efficiency single-phase AC to DC conversion is achieved with the TP65H035WS, a diode-free Gallium Nitride (GaN) FET bridge with low reverse-recovery charge. 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.

  • Input voltage: 85VAC to 265VAC, 47Hz to 63Hz

  • Input current: 18Arms; 2000W at 115VAC, 4000W at 230VAC

  • 10% overload short time: 19.8Arms; 2200W at 115VAC; 4400W at 230VAC

  • Ambient temperature: <50ºC

  • Output voltage: 387VDC ± 5VDC

  • PWM frequency: 66kHz

  • Auxiliary supply: 12VDC for bias voltage

  • Power dissipation in the GaN FET: Limited by the maximum junction temperature; refer to the TP65H035WS datasheet
