DC/DC Converter

It is designed for use in 10~18m trolleybuses. It has high quality electrical isolation capability, and converts the wire power into controllable electric energy to supply trolleybus.

DC/DC Converter
KEY FEATURES
  • High Reliability
    Mean time between failures more than 50000 hours.

  • Mode Switching
    Automatically switch working modes according to the load conditions.

  • Double Insulation Protection
    No boarding step voltage risk and bus service operational loss under single insulation failure.

  • Modular Design
    The main circuit is based on multiphase DAB topology, which is easy to be modularized and leads to lower spare part types.

  • Wide Input Range
    350~900VDC input compatible with both 600VDC and 750VDC contact lines.

  • Wide Output Range
    400~750VDC output compatible with most commercial electric vehicle motor drives.

  • High Safety, High Intelligence
    Automatically power off after checking, to prevent misoperation;
    Two high electrical isolation relay connected in series, to provide;
    Automatic offline insulation checking and annunciation, no manual intervention.
