Abstract

The wireless power transfer technology is now attracting attention as the technology which contributes to improvement of a cruising range of electric vehicles aiming at the carbon-neutral society. We have been developing the capacitive power transfer method, which was one of two categories of methods, classified in general, of the wireless power transfer technology required to realize the dynamic wireless power transfer. This time, we will report on the coupler which is a necessary component for the wireless power transfer technology that we have realized a high-power transfer of 10 kW class by developing measures to mitigate the heat generation and other problems.
