2kW DC/DC Convertor for Electric Scooter

A boost DC/DC convertor was developed to convert the output DC power from the fuel cell to a regulated DC output of 86V, to power an electric scooter motor with stored hydrogen onboard. This work was done for HySA Systems at the University of Western Cape

Bi-Directional DC-DC Converter

HPT supplied a Bi-Directional DC-DC converter system for a 60kWh battery bank as an additional component for the DC distribution project at Hynor Lillestrom. This converter controls the energy flow between the Battery Bank and the DC Distribution System at Hynor LillestrØm Hydrogen Refuelling Station.

DC/DC Convertor for first Hydrogen Refuelling Station

HPT developed a 30 kW DC-DC Power Interface for a Solid Oxide Fuel Cell system. The Power Interface was integrated into the first hydrogen refuelling station currently under construction at HyNor Lillestrøm’s demonstration site in Akershus Energy Park, near Lillestrøm in Norway.  
The DC-DC converter was developed to interface the SOFC system to the DC distribution network of the refuelling station. The DC-DC converter ensured the correct regulation and control required to maintain constant loading at the fuel cell terminals was achieved. The DC-DC converter would perform the necessary start up, shut down and transient control functions required to maintain stable operation of the SOFC system.

The unit features a SCADA interface, Data Logging and Remote Monitoring and Control System
