Abstract

A power feeding device of three-leg core type having a primary and secondary cores which appear to be a three-leg core cut into two pieces at the legs and form a magnetic circuit including gaps by being coupled to face the cut surfaces, and a primary and secondary windings wound coaxially around the central leg section, with the primary core and primary winding constituting the power supply part and the secondary core and secondary winding constituting the power receiving part. The power feeding device based on this winding structure achieves a far better power transfer efficiency as compared with the conventional counterpart having the primary and secondary windings wound separately on a pair of E-shape cores.
