The demand for a DC power distributed system is increasing as renewable energy sources and DC electrical load are proliferating. For the automation of a power system, a magnetic contactor for the DC power system is required. The conventional magnetic contactors are mostly equipped with a solenoid magnetic actuator. However, the conventional magnetic contactor has problems with continuous power consumption, and heat generation. To address these problems, a permanent magnet type DC magnetic contactor is proposed in this paper.
