Bidirectional 400V-12V DC/DC Converter Reference Design


The Bidirectional 400V-12V DC/DC Converter Reference Design is a microcontroller-based implementation of an isolated bi-directional DC-DC converter.  A phase shifted full-bridge (PSFB) with synchronous rectification controls power flow from a 400V bus/battery to the 12V battery in step-down

  • Digitally-controlled isolated bidirectional DC/DC converter based on the TMS320F28035 microcontroller 300W rated output operation in either direction High voltage DC input: 200-400V Low voltage DC output: 9-13.5.V
  • DC/DC Converter
  • DC Charging (Pile) Station
  • Power Converters & Chargers for Construction Equipment
