The plug and outlet for home appliances in DC low voltage micro-grid system

Abstract

This proposed paper introduces the more effectiveness of power transferring in dc micro-grid power distribution in order to comprehend the usage of home appliances. A 300V 5-level diode clamped multilevel is operated as power source for contactless power transfer with a selective harmonic elimination(SHE) technique, and the output is set at 48 V 300W with the efficiency at 92.6%. The converter generates 200 kHz switching frequency to send a highly magnetic coupling through primary coil over ferromagnetic material in tight coupling condition. The paper aims are to eliminate the electric shock, galvanic isolation and arch free in dc to dc power conversion. Additionally, the lower %THD can reduce designed parameters which mean the power density will be increased. The output will be illustrated in both simulation and implementation results.
