Abstract:

Recently, high-power wireless power transfer (WPT) technology for fast battery charging in applications such as electric vehicles has been actively researched. This paper presents a novel three-phase resonator as a crucial technology for high-power wireless power transfer systems. The proposed resonator’s leakage magnetic field, efficiency, voltage, and current characteristics are compared with those of a conventional single-phase resonator, aiming to assess its suitability for high-power wireless charging applications. The analysis is performed by comparing a three-phase resonator with a single-phase resonator of the same diameter using the electromagnetic (EM) simulation tool. The results showed that the three-phase resonator generates less leakage magnetic field and lower secondary current than the single-phase resonator when the distance between the resonators is close. It was shown that the three-phase resonator is more advantageous in terms of human safety compliance and receiver weight reduction. This paper shows how resonator design can address leakage magnetic field concerns and system limitations in high-power WPT system design.
