Kolibrik DC/DC Converter for Fuel Cell Stacks

This modular solution for power DC/DC conversion is developed specifically to address wide ranges of varying key parameters of hydrogen fuel cell and electrolyzer applications. This solution is based on modules that can be parallelized in required count. Converters can be digitally controlled or monitored.

Modules allow for constant voltage control and constant current control or limitation. That is ideal for applications where a system battery is used, so the output can change modes according to battery charge status and application power demands. Current control feature can be used also for parallelization of more hydrogen fuel-cell sources, where each source can be enabled individually and can contribute with a different current or power.

We provide models with custom-specified parameters, with different cooling and mechanical setups, or with complete custom development service for mass production.

For detailed specifications of a solution for your project, please contact us and specify your key parameters – voltage and current range of input and output, preferred cooling, controller demands, application-specific parameters, etc.

DC/DC Converter Applications

Fuel-cell stack output power conversion for application power (e.g. fixed 24 V or 48 V output)

BoP power supply

Intelligent conversion for application with battery in peak-shaving setup – const. V/I mode depending on battery charge status and application power consumption

Parallelization of more fuel-cell power sources – each source can contribute with different power

Electrolyzer power supply with current control and voltage limitation

Pre-convertors for 3^rdparty industrial converters and inverters that have improper input voltage range for direct connection to fuel-cell stacks

Example: H2FC stack (35 ... 72 V) → DC/DC converter (output 48 V) → inverter 48 VDC / 230 VAC
