A Novel DC Circuit Breaker Design Using a Magnetically Coupled-Inductor for DC Applications

In the attempt to simplify the steps of converting power into its simplest form, new microgrids will be conceptualized in the DC format. Certain power systems and power conversion components are highly available but, as it applies to DC circuit breakers, various designs are currently in the experimental stage. The most significant drawback of such a system is that interrupting current that is without zero crossing causes a sustained power arc. This paper introduces a novel circuit breaker model for DC, which utilizes a coupled inductor circuit breaker, and a mathematical model of insulated gate bipolar transistor (IGBT) has been developed. This Type of DC circuitbreaker demonstrates the advantages of its application in consumer electronics.
