DEVELOPMENT AND TESTING OF A 1 KV SOLID STATE CIRCUIT BREAKER

Recent increases in dc power system usage have created a need for dc capable circuit breakers. One method to achieve this is through the development of solid state circuit breakers (SSCB) that utilize power electronics to break the circuit. The use of power electronics allows for the breaking of a circuit quickly with no need for a natural current zero-crossing point for arc-less interruption of current. This report details the development of a 1 kV 0.2 kA SSCB. The control scheme is discussed as well as its implementation in real-time simulation (RTS).
