| Summary: | 碩士 === 國立臺灣科技大學 === 電子工程系 === 104 === This thesis focuses on the analysis, design and implementation of wireless power transfer (WPT) system with bidirectional power transfer capability for electric vehicle charging and vehicle-to-grid (V2G) application based on series-series resonant compensation topology. Firstly, a brief introduction to basic principles of WPT is given and the equivalent circuit models of loosely coupled coils for WPT application are reviewed and analyzed. Then the characteristics of series-series compensated WPT system at different operating points are analyzed.
A design method that can guarantee reliable operation of series-series compensated WPT system under given coupling coefficient variation range, load range and allowed operating frequency range is proposed in this thesis. Finally, a prototype 3 kW WPT system with bidirectional power transfer capability is built and tested. The prototype efficiency is 96% under full load and 210 mm coil separation and 95% under full load and 250 mm coil separation.
