3.6 kW PFC totem pole with inrush current limiter reference design using TN3050H-12WY and SCTW35N65G2V

Overview

TopologyPower Factor Correction
IC revision1

Description

The STEVAL-DPSTPFC1 3.6 kW bridgeless totem pole boost circuit achieves a digital power factor correction (PFC) with inrush current limiter (ICL). It helps you to design an innovative topology with the latest ST power kit devices: a silicon carbide MOSFET (SCTW35N65G2V), a thyristor SCR (TN3050H-12WY), an isolated FET driver (STGAP2S) and a 32-bit MCU (STM32F334).This reference design also opens the path to a compact converter running at 75 kHz offering a high efficiency at full load (97.5%) and a low THD distortion (5 % max. at 10 % of maximum load).It achieves a robust circuit that meets EMC standards up to 4 kV delivering high switching lifetime with reduced EMI emissions.The thyristor SCR used as AC line polarity switcher allows achieving an active current limitation at power up or line drop recovery: the PFC efficiency is optimal and no EMI bouncing effect occurs.The reference design includes a power board bridgeless totem pole boost, an inrush limiter circuit, switch drivers, an auxiliary power supply, a control board with its MCU, a PFC/ICL control firmware and an adapter board for software debug.

Features

  • 97.5 % efficiency at full load
  • Max. 5 % THD at 10 % of full load
  • Compact PFC converter
  • Higher switching lifetime
  • Compliant with EMI norms at 4kV
  • RoHS compliant
  • WEEE compliant

Typical applications

  • Motor drive, motion control
  • Server/Telecom SMPS
  • EV/HEV on-board chargers / Charging stations / UPS, industrial battery charger
