Abstract: With the fasting growth of renewable energy resources and DC supplied loads, DC electrical systems have been increasingly received attentions all over the world. DC breaker systems play a key role in protection systems for disconnecting sources and loads, and they are also used mainly for removing faulted sections from the system accurately and reliably. Solid state DC breakers benefit from fast response time and compactness features; however, due to the lack of zero current realization and high-power losses, the reliability and efficiency of these devices is low. The system proposes a solid-state DC breaker for medium voltage DC (MVDC) systems.
