Description

This document introduces a complete Infineon Technologies AG system solution for an 11 kW bi-directional DCDC converter. The REF-DAB11KIZSICSYS board is a DC-DC stage with a wide range output using two inductors and two capacitors (CLLC) resonant network with bi-directional capability. This converter can operate under high power conversion efficiency, as the symmetric CLLC resonant network has zero-voltage switching capability for primary power switches and synchronous rectification commutation capability for secondaryside output rectifiers. The converter could change the power flow direction, and its maximum power conversion efficiency was around 97.2% during the operation without synchronous-rectification.This document shows the board using 1200 V CoolSiC™ MOSFETs in TO247-4 package and EiceDRIVER™ 1ED compact gate driver ICs, which leverage the advantages of SiC technology including improved efficiency, space and weight savings, part count reduction, and enhanced system reliability.

Features

  • Novel Quasi-Resonant switching scheme
  • Rapid and adjustable start-up with cascode configuration
  • 2 level selectable active burst mode level
  • Built-in digital soft-start
  • Cycle by cycle peak current limitation
  • Digital frequency reduction with decreasing load for higher efficiency
  • Adjustable line input over-voltage and brown IN/OUT protection
  • V CC pin short to ground protection
  • OLP, output short, output over-voltage, OTP with hysteresis and V CC over/under voltage protection
  • Auto-restart for all protection features

Typical applications

  • Offline aux SMPS for server,PC power,aircon,refrigerator and audio, Offline main SMPS for adapter,set-top-box, water purifier,TV,industrial SMPS and POE.
