| Outline of Final Research Achievements |
Electric vehicles are increasing for protecting the global environment. Technological development is underway to charge and discharge between the power system and storage batteries of electric vehicles by wireless power transmission. Wireless power transfer makes it possible to charge the battery even while stopping at a signal or running, and the battery capacity of the electric vehicle can be reduced, which has many advantages. The requirements for wireless power transmission circuits are small size, high efficiency, and bidirectional power conversion. In this research, we have developed a compact and highly efficient bidirectional wireless power transmission system that uses a matrix converter that directly converts a three-phase power supply to high frequencies.
