PI Based Coupled Inductor Circuit Breaker

According to the paper we are developing the new type of DC circuit breaker. In order to reduce the power conversion step for future micro grid with the renewable energy source which is best for the DC power system. Therefore, according to the system components like source, load and the power conversion which can identify easy and ready to use. There the main limitation is to interrupting a current which does not have a zero crossing will sustain an arc. Here we are utilizing the short conduction path between the breaker and load along with mutual coupling to automatically and rapidly switch OFF in response to a fault. we are used BESS (battery energy storage system) for Output side to store the energy with PI controller.
