Title: ELECTROMAGNETIC INDUCTION APPARATUS FOR POWER TRANSFER
Abstract:
An electromagnetic induction apparatus for power transfer may include a first portion and a second portion. The first portion has at least one loop of central coil is winded on the central magnetic core, and the second portion has at least one loop of toroidal core winded on the toroidal magnetic core. When the first portion is inserted into the second portion, the toroidal coil is located around an outside periphery of the central coil. Since the central coil and the toroidal coil are mutual inductance on the same magnetic core, the electromagnetic induction efficiency is improved, leading to enhancing more than 50% of the power transmitted rate.
