Bidirectional converter “Bereza”

  • Зарядная станция "БЕРЕЗА"

    The bidirectional converter “Bereza”  is a patriotic development of Russian Electrotechnical Society LLC, which includes all modern technologies in the field of converter technology. The basis of the bidirectional converter is powerful IGBT transistors.

    The versatility of the bidirectional converter of the “Bereza” series allows it to be used for various purposes:

  • Charging station for both land and water electric transport.
  • Energy storage systems (ESS).
  • Uninterruptible power supply (UPS).
  • Frequency converter (FC).
    Bidirectional converter " Bereza " can be used in the following areas:
  • in the metallurgical and oil and gas industries, where it is necessary to ensure continuous operation of drives involved in the technological process;
  • in the field of urban transport for charging batteries of electric vehicles;
  • in the IT field for uninterruptible power supply to critical consumers, being the main part of an uninterruptible power supply;
  • as energy storage devices for solar and wind power plants.
Input power supply 3х380 V, 50 Hz
IP rating IP22
Cooling type Air
Output voltage DC Up to 900 V
Output current 200…1400 А
  • Bidirectional converter based on most advanced high-power IGBT transistors is the main component of charge station
  • May operate with ESS and other load
  • Own control system with intuitive interface and integrated technical diagnostics tools
  • Remote control and monitoring of the System
  • Non-volatile error and alarm history
  • Data exchange with third party systems.

Charge station ensures remote and local control, record keeping of service hours, as well as monitors technical condition of users with alarm signaling, etc.



The station consists of two sections:

  • input section ensures power input, switching and supply to secondary users, and protection of the internal devices against short circuit.
  • conversion section ensures rectification, voltage level generation, current limit set point, charge station control from local control panel, compatibility with peripheral units and ship systems.
