This project builds upon an existing project which is developing a high efficiency multi-port DC-DC converter for use in hybrid and electric vehicles, aerospace and military applications. Significant cost and weight reductions are being demonstrated by the use of novel circuit topologies and the use of Silicon Carbide switching technology. This project will move the design to a mature technology readiness level with reduced system cost by developing the supply chain for the system, validating the robustness of the components, and optimising the packaging and thermal management.

DC/DC converters are essential in electric and hybrid electric vehicles. These electronic devices step-up or step-down the battery voltage to a voltage level that suits the electric motor, the cabin supply or other essential loads. Current DC/DC converters are still expensive and heavy. A consortium of six UK manufacturers (Lotus, Turbo Power System, Industrial Capacitors Wrexham, International Transformers, Dynex, Hiflux) , one vehicle integrator (Hyperdrive) and Newcastle University are developing a new dc/dc converter design that reduces cost by up to 50% and weight by up to 40% compared to standard dc/dc converters. The main focus of their research is to reduce the inductor size which makes 50% of the overall weight and cost in a power dc/dc converter. A radical new converter design holds the key to achieve these targets. The 30 months programme is being supported by investment from the government-backed Technology Strategy Board (TSB).
