Model and Frequency Control for Three-phase Wireless Power Transfer System
摘要
Abstract
Owing to the "dead spot" in the traditional three-phase wireless power transfer(WPT)system with symmetric magnetic mechanism,a three-phase WPT system with asymmetric magnetic circuit was deeply discussed. Additionally,the model was established and the parameters of the system were optimized. Then, a stabilized frequency and high efficiency system design method based on impedance conversion was proposed to improve its frequency stability and efficiency,for which the variation of load could seriously affect the resonant frequency and efficiency of the system. Finally,the viability of the proposed design method is verified by experiments, and the results suggest that the proposed method is reliable and feasible.关键词
