A High-Power Multirectifier WPT System With a Hybrid Modulation for Wide-Range ZVS Operation
Wireless power transfer (WPT) systems for electric vehicles (EVs) may require primary-side or dual-side control to meet a variety of power regulations (PRs). However, this architecture requires frequent Wi-Fi communications between the ground assembly (GA) and the vehicle assembly (VA) while achieving wide-range PR, which may have a significant time delay. To address these issues, a new dc-link parallel ac-link series multirectifier (DPAS-MR) architecture is proposed for the WPT system in this article. The proposed topology and the hybrid modulation method are presented in detail. In addition, zero voltage switching (ZVS) operation, power loss, hybrid power device architecture, and design procedure are analyzed. A wide range of output PR can be realized by only using secondary-side control without dual-side communication. An 8-kW DPAS-MR WPT prototype with three rectifiers is built and the output power ranges from 3 to 8 kW with a maximum overall efficiency of 93.5%, which verifies the effectiveness of the proposed system.
