Delta 6.8kW DC-DC Power Converter is used for the Hydrogen Generator Set. The unit features a multi-phase interleaved boost topology design with 6 phase diagrams to shunt sudden rise currents from hydrogen fuel cells. It effectively prevents abrupt current spikes that hydrogen fuel cells may produce and can damage the inside parts. The unit allows 50 V to 150 V wide input voltage and converts it to 400 V to 600 V output voltage for the Li-ion batteries of electrical devices. The RS-485 Modbus protocol and built-in digital signal processor (DSP) allow users to have real-time bi-directional communication with the unit and send the required signals
