This research presents the development of a three-phase inductive coupled structure for contactless charging paddle system for electric vehicles. Several types of core shape are introduced and their magnetic circuits are simulated and analyzed. Therefore, a delta-type three-phase core structure is presented. The resonant frequency tracking control is realized in order to reduce the VA rating of primary three-phase half-bridge inverter and to achieve maximum power transfer capability to load. A prototype of the proposed contactless charging paddle system with aligned three-phase inductive coupled structure for electric vehicles is established in laboratory to confirm the functional operations and performances. Simulations and experimental results are demonstrated to show that the three-phase contact-less charging paddle system is more suitable for high power application due to the improvement of power flow smoothness between the exciting source and load.
