Abstract

The development and application of contactless power transmission technology has given widespread attention to the charging method of marine vessels. Due to the safety hazards of the traditional plug-and socket vessel charging mode, and the resistance to deviation and efficiency of the contactless power transmission system based on magnetic resonance oscillation. This paper proposes an EE-type loosely-coupled transformer based on the electromagnetic induction type, with small magnetic resistance and low leakage inductance characteristics, with a higher coefficient in near distance transmission, and can realize a wide range of transmission in the hundred-watt level to the kilowatt level, with a high transmission efficiency. The high efficiency of the magnetic coupling mechanism composed of the loose-coupled transformer and the SN topology circuit with strong coupling capability is simulated and verified by using finite element software. The transmission efficiency could reach 83.3%, under assigned load, verified the feasibility of the scheme and experiment.
