Outline of Final Research Achievements

Smart houses are expected to maintain electric grid’s stability in spite of large amount of renewable energy. It is a problem that recharge batteries are too high-cost for wider diffusion of them. Vehicle to Home (V2H) system which connects electric vehicle to home is paid the most attention as promising solution for reducing battery cost. A V2H system through wireless power transfer is easy to use by wide range of users. However conventional bidirectional wireless power transfer apparatus needs 8 power switching devices. It is not suitable to V2H system which is home use because of its complex and high-cost configuration. Developed has been a new type of bidirectional wireless power transfer apparatus which can operate by only 2 power switching devices to offer a simple and low-cost but high performance wireless V2H system.
