Abstract

This paper proposed the operational region of novel multi-coil series-series compensation in wireless power transfer (WPT) system specially designed for electric vehicle (EV) applications. The new idea of additional intermediate circuit increases zero phase angle (ZPA) frequencies. The proposed WPT system has two operational regions with three ZPA frequencies. The ZVS operational regions and the three ZPA frequencies are validated by the AC-sweep of actual load and the frequency response of system is presented. The suitable operational region has been validated by the experimental results. Finally, the experimental results show the two-operating condition under different power levels. ฉ 2019 IEEE
