Description

Continuous-Conduction-Mode (CCM) Totem-pole power factor correction (PFC) is a simple but efficient power converter.  To achieve 99% efficiency, there are many design details that need to be taken into account.  The PMP20873 reference design uses TI’s 600VGaN  power stage, LMG3410, and TI’s UCD3138 digital controller.  The design overview provides more details on the CCM Totem-Pole topology operation, gives the detail design considerations of the circuit, and provides magnetics and firmware control design considerations. This converter design operates at 100KHz. A soft start at AC line crossover minimizes current spike and lowers THD.  The PFC Firmware measures AC current and PFC output voltage in real-time and predicts the dead time needed for the switch node to complete a full swing. The adaptive dead time control effectively minimizes both switching loss and GaN FET body diode conduction loss. A GUI is available to support parameter setting and control loop tuning.

Features
  • 1kW, 99% efficiency at 100kHZ and 230V (Power derates to 600W for 115V long time operation)
  • TI’s LMG3410 GaN power stage with an integrated driver ensures circuit reliability and eases design
  • OCP, OTP and OVP with adjustable switching node dv/dt setting
  • Full digital control
  • Adaptive deadtime control and low AC crossover current distortion
  • GUI available for PFC parameter setting and control loop tuning
