In this paper we are implementing a z-source inductor based circuit breaker for DC application. Therefore, in order to overcome the power conversion steps and the micro grid with the renewable energy sources which is utilized for the dc power systems. According to the system components there are various source load with the power conversion which is readily available. therefore, the main limitation will be interrupting a current which does not have a zero crossing will sustain an arc. According to the paper we are implementing a new type of dc circuit breaker. Z-source networks provide an efficient means of power conversion between source and load in a wide range of electric power conversion application. It Works as a buck-boost inverter. And it is also utilized for a short conduction path which lies between the breakers and loads along with the mutual coupling to automatically and rapidly switch OFF in response to a fault. According to the proposed breaker we also utilized the crowbar type switch at the output so that it can be used as a dc switch. By using simulation result we can analysis the proposed topology by using a new dc switch which has been included.
