A German research team has explored the technological basis for reducing the energy losses in power grids and electric devices by more than half. This can be made possible through the use of direct current (DC). DC allows for smaller power losses when compared to the alternating current (AC) used today. The five project partners from industry and science investigated the foundations of a semiconductor-based and completely electronic circuit breaker that can be used for future DC power grids and applications. Such a circuit breaker will enable to use direct current wherever alternating current is used today.
