Power Electronics

We are addressing challenges of reducing carbon dioxide emissions. Driven by environmental concerns, established mechanical technologies such as combustion engines are being replaced and enhanced by energy efficient, electrically driven machines. Lightweight, compact, and ultra-efficient power electronic converters are needed for the next generation of electric vehicles. Ultra-high efficiency is required across all electricity use: from megawatt high-voltage converters in the electricity grid, down to microelectronic environmental sensors with microwatt consumption. Renewable energy capture requires highly reliable converters with health monitoring. We are exploiting the step-change in performance of new GaN and SiC power semiconductor devices, to develop technologies that will benefit applications across a wide range of engineering sectors and scales.
