EVAL-PFC5KIKWWR5SYS

Overview

Evaluation board for 650 V TRENCHSTOP™ 5 WR5 IGBT for Aircon & EV charger applications

This board is a fast switching, analog-controlled two-channel interleaved 5 KW PFC converter with our TRENCHSTOP™ 5 WR5  IGBT IKW40N65WR5. It is designed to show case the use of WR5 IGBT with high switching frequencies up to 60 kHz in interleaved PFC application, which enables many system benefits such as smaller size PFC choke, overall system size and as well as BOM cost.
The board demonstrats a very effective example of design with our low side gate driver 1ED44175 and rapid1 power silicon diode IDW60C65D1.

Summary of Features

  • Interleaving operation
  • Adjustable switching frequency
  • Continuous conduction mode
  • Average current control
  • Cycle-by-cycle peak current limiting
  • Thermal shutdown feature for power semiconductors

Benefits

  • Achieve twice the fsw and half the ripple current effect than standard boost PFC
  • Smaller EMI filter
  • Lower inductor current ripple than single PFC operation
  • Zero inductor current ripple at 50% duty cycle
  • TRENCHSTOP™ 5 WR5 IGBT enables high fsw, which allows to place the inductors on board
  • High efficiency up to 97.8% can be achieved
  • Easy and quick devices selection
  • Shorten development period
  • Reduced system costs
  • Smaller form factor
