Energy Efficient Converters Using GaN Power Devices
Efficient power conversion systems are at the heart of the worldwide effort for a green economy, since they can minimize losses and save energy and contribute thus to achieve a better CO2 balance sheet. Semiconductor power devices are a central part of any power conversion circuit and are ubiquitous in our daily lives: they transform voltages for a multitude of appliances, such as from the 220V AC mains to a 12V DC end-user appliance and enable to convert from DC (such as a battery in an electric car) to AC (such as a motor drive) and vice versa. Highly efficient power switching devices are a key for successful introduction of full electric vehicles into the market.
E2COGaN will target the demonstration of GaN-on-Si as a disruptive high voltage (HV) technology and High Electron Mobility Transistors through the whole value chain up to demonstrators with high industrial, societal and environmental relevance. Aims are higher efficiency, higher switching frequency, smaller footprint and weight and competitive cost on system level with respect to Si or SiC.
