Fuel Cell Converter FCDC500 DC/DC

  • Integrated fast PLC
    • The DC/DC has mostly the same software features as the well-known drive train inverters from ARADEX. Using a very fast integrated PLC the DC/DC converter can be adapted to almost each kind of fuel cell without using an additional external controller. The device can be extended with software modules written by customer.
  • Integrated storage oscilloscope
    • Due to the integrated FPGA functionality means that the sample frequency for voltage, current, power and other system variables is 80 kHz. Values can be displayed in our Analyzer software and exported to external systems. This functionality accelerates commissioning and service.
  • Combination of FPGA and DSP
    • Fast and smooth control of fuel cell current. Prepared for additional functions such as modulating fuel cell current for diagnostics.

    ARADEX is focused on high voltage drivetrains and DC/DC converters for mobile applications such as trucks or mobile working machines. For drivetrains we offer motors and inverters including technologies like VirtualSensor to support your added-value functions in your application. Our high voltage DC/DC converters are mainly used to connect a fuel cell to the HV-system and offer integrated PLC-functionality for optimum coworking with the fuel cell. Our typical power range of inverters and DC/DC cover applications from 50 to 1200kW and voltage up to 900VDC.
