Description

This document describes the details of the REF_10KW_3LBUCK_SIC400 evaluation platform and serves as a user guide for its safe operation. The topology used in this platform is a 3-level-flying capacitor Buck DC/DC converter, which can also be reconfigured to be used as a 2-level Buck DC/DC converter. The primary goal of the platform is to enable the evaluation of CoolSiC™ G2 400 V and 650 V MOSFETs in TOLL and D2PAK-7 packages, as well as the EiceDRIVER™ 1ED-series isolated gate-drivers, and XMC4400 MCUs for high performance SMPS applications.

Features

  • Evaluate CoolSiC™ 400 V/650 V G2 MOSFETs
  • Compare 3-level vs 2-level topologies
  • Flying capacitor balancing algorithm
  • Compact planar transformer gate supply
  • Test bipolar vs unipolar gate drive
  • Adjustable gate-drive voltage
  • Supports Kelvin-/Power-Source gate drive
  • Low inductance high-power design
  • Heatsink-based cooling system

Typical applications

  • Renewables
  • Energy Storage Systems and UPS
  • High voltage solid state power distribution, Server (AI) and telecom SMPS
  • Motor control and drives
  • Class-D Audio
