1.2 kW High Efficiency Bridgeless Totem Pole PFC Evaluation Kit

This evaluation kit demonstrates the performance benefits and design considerations of a high efficiency, high power density 1.2kW Bridgeless Totem Pole PFC (BTP PFC) controlled by advanced digital control methods coupled with GaN Systems’ E-HEMTs.

Technical highlights

  • Continuous Conduction Mode (CCM) BTP PFC
  • Universal AC input (85 V- 264 V)
  • 1.2 kW continuous output power @ 240V
  • 600 W continuous output power @ 85V
  • 385 VDC regulated output voltage with firmware adjustability
  • Adaptive deadtime control
  • Hysteretic current control with cycle by cycle current limiting, fast transient response and inductor current measurement
  • > 99% peak efficiency
  • > 0.99 power factor
  • Low THD (< 3%)

Features

  • Fanless operation
  • Self-powered. External DC supplies are not required
  • Bi-directional power flow, suitable for ESS and OBC systems
  • Low part count and BOM cost due to highly integrated SA4041 controller
  • Easily scaled to 10kW with magnetic and GaN device selection

Created in partnership with Solantro Semiconductor Corp, featuring the SA4041 Digital Power processor
