AFE DC/DC Converter

SECOM PowerAFE DC/DC Converter

AFE DC/DC Converter

TheAFE DC/DC is a bidirectional power converter, designed for advanced industrial applications, with particular attention to hydrogen-based energy systems.
Based on an Active Front-End topology, it enables precise control of the energy flow in both directions, offering maximum efficiency and integration flexibility.

Main features:

  • Bidirectional DC/DC topology with IGBT synchronous conversion
  • Advanced digital control, via integrated DSP and FPGA
  • High efficiency thanks to dynamic management of the switching cycle
  • Wide voltage range input/output (up to 1500 V)
  • High switching frequency to reduce clutter and losses
  • Modularity and scalability: configurations from 50 kW to 500 kW
  • Compatibility with storage systems, fuel cells, electrolysers and other hydrogen-related technologies
  • Advanced cooling system for continuous operation even in harsh environments

Main applications:

  • Power supply of electrolysers for hydrogen production
  • Fuel cell systems for mobility or energy backup
  • Storage systems (batteries, supercapacitors)
  • Integration between microgrids and renewable sources

Competitive advantages:

  • Fully bidirectionally managed energy flow
  • High power density
  • Digital communications (Modbus, CAN, Ethernet)
  • Compact design and simplified maintenance
