Abstract
The dynamic wireless power transfer (DWPT) system allows that the vehicles can be re-powered during operations. The DWPT technology will significantly make the transportation more efficient, and users are not worried about being stuck in the road due to continuous on-road powering. The main challenges in the practical application of DWPT system are unstable coupling, limited system efficiency and low system stability. In order to solve these issues, the key research effort concentrates on ferrite structure, compensation network and control method for a DWPT system. Based on the modularized EV and 3D marine robot charging systems, a universally-applicable ferrite optimization algorithm and adaptive control methods are discussed. In addition, the sensing technology based on the DWPT is also investigated. The essential characteristics of the proposed methods are reduced complexity (e.g., no position sensor or communication unit involved) and improved dynamic performance of the system.
