Abstract

High-power wireless transmission system becomes a key technology for the advance of battery-powered devices. The wireless power transfer devices are currently dominated by the inductive and capacitive wireless power transfer systems, which have relatively low power transmission capacity and low efficiency rather than the wired power transmission. The work presented in this paper proposes an alternative method of high-power transmission system, based on a variable speed motor system with a magnetic coupling. It enables high-capacity power transmission, high efficiency, and low possibility of failures, and the performance of the proposed scheme is verified by simulation and experiments.

대용량 무선 전력 전송 시스템은 ESS, 배터리 장치 등의 발전을 위한 핵심 기술이다. 무선 전력 전송 장치는 현재 자기유도 및 자기공진 기술들이 주를 이루고 있으며 유선 전력 전송에 비해 전력 전송 용량이 낮고 효율이 낮은 단점이 있다. 이 논문에서는 자기 결합을 갖는 가변속 모터 시스템을 기반으로 하는 대용량 무선 전력 전송 시스템을 제안하고자 한다. 제안된 방식은 대용량 전력 전송이 가능하며, 고효율과 낮은 고장 가능성의 장점을 가지고 있으며 시뮬레이션과 실험을 통해 제안된 기법의 성능을 검증하였다.
