Abstract:

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.

I. Introduction

In recent years, most electric devices such as information technology (IT) devices, television (TV), Audio/Video (AV) devices, personal computer (PC) and facsimile (fax) are operated by direct current (DC) electrical power. Furthermore, renewable energy which generates DC power is increasing rapidly. Hence, the DC power distributed system has been attracting attention. DC magnetic contactors (DCMC) are essential devices to operate the DC power distributed system.
