Power Electronics for Clean Energy

Solar inverters, wind turbine control systems, energy storage management electronics, and grid connection equipment require high power density, a wide environmental operating range, and long-term reliability.

Björn Tech brings POLYRACK enclosures, YCC Fan cabinet fans, Pada Engineering liquid cold plates, Sheen thermal films and potting compounds, and Innodisk's wide-temperature memory, isolated interfaces and edge AI systems together as one system. From the inverter power stage to the monitoring unit in the outdoor cabinet, every component is chosen for the conditions at the site.

Recommended in this sector:

  • POLYRACK: CasTech (up to IP65 monitoring and control unit) and FrameTech (19" energy management in a cabinet).
  • YCC Fan: EC and DC axial fans: inverter and battery cabinets.
  • Pada: Liquid cold plate: IGBT/SiC in solar inverters and battery converters.
  • Sheen: Thermal Film (above 4 kV AC) and thermal potting compound (self-levelling).
  • Innodisk: DDR5 wide and ultra temperature; isolated CAN and serial modules; industrial SD/microSD; APEX-A100 (-40 ~ 70 °C) and APEX-E100: field monitoring and AI.

Outdoors, Under Load, for Decades

  • High power density

    IGBTs and power semiconductors in inverters and converters generate a lot of heat in a small volume.

    Our answer Liquid Cold PlatesThermal Film

  • Wide environmental operating range

    Equipment at solar and wind sites must operate in the field while protected against temperature, dust and moisture.

    Our answer CasTechDDR5 Wide and Ultra TemperatureAPEX-A100

  • Long-term reliability

    Energy systems stay in the field for many years with limited access for maintenance.

    Our answer Thermal Potting CompoundIndustrial SD and microSD

  • Efficient active cooling

    Where active cooling is required, fan energy consumption and airflow must be optimised.

    Our answer EC Axial FansDC Axial Fans

  • EMC in the power cabinet

    Control and energy management units share the cabinet with switching power stages; their enclosures must be EMC-ready and have a planned heat path.

    Our answer CasTechFrameTech

  • Isolated field communication

    Battery management, converters, meters and weather stations communicate next to high-power switching; the interfaces must be isolated.

    Our answer Isolated CAN Bus ModulesIsolated Serial Modules

  • Unmanned sites

    Solar fields, wind farms and substations are rarely staffed; cameras and AI have to detect intrusions and panel faults on site.

    Our answer APEX-A100APEX-E100

Thermal Management for Inverters and Storage

In an energy system, heat and the site environment decide the service life. That is why we plan the system layer by layer: POLYRACK CasTech and FrameTech enclosures lay the mechanical and EMC foundation, and YCC EC and DC fans move air through inverter and storage cabinets with as little energy as possible.

At the power stage, Pada Engineering liquid cold plates and extruded heat sinks carry the heat of IGBT and SiC modules away; Sheen thermal films insulate the semiconductors from the heat sink, and thermal potting protects and insulates the electronics while conducting heat. Innodisk completes the control and monitoring side with wide-temperature memory, industrial microSD cards, isolated CAN and RS-485 interfaces and Innodisk APEX systems for AI at unmanned sites.

The result: one bill of materials, one technical contact and a system designed for the conditions at the site from the start.
