5kW Fuel Cell DC/DC Converter Module


The 5kW Fuel Cell Inverter system converts a 55VDC – 90VDC input to create a nomional 650V DC output. The DC input voltage is sourced from a Fuel Cell.

Power flow in this system is uni-directional from the low voltage side. The DC Module is galvanically isolated.

The DC Module interfaces directly to the 5kVA Inverter Module with grid connection available from Creative Power.

These modules are designed to provide a ready made microgrid test platform environment

The Module has an isolated RS485 Modbus interface that provides control over real power flow.


Creative Power specializes in the development of custom solutions to meet specific customer requirements. This is achieved through Creative Power's extensive "building blocks" of controllers and power stage designs. Contact us if our listed products don't quite meet your requirements.
