METHOD OF DESIGNING POWER FEEDING SYSTEM AND POWER FEEDING SYSTEM

摘要

Disclosed is a method of designing a power feeding system achieving critical coupling at a desired resonance frequency without adjusting a size or a distance of a coil, and thus obtain high transmission efficiency over broad band. The method includes designing impedances of the power feeding and the power receiving unit to be small as a resonance frequency between the power feeding helical coil and the power receiving helical coil becomes small by adjusting impedances of the DC/AC converter and the AC/DC converter.
