摘要： A non-contact electric power transmission device comprising a feeding member which includes an induction coil to which electric power is applied and the non-contact electric power transmission device further comprising a plurality of fed members which each further comprise an induced coil placed within a magnetic field produced by the induction coil. The fed members differ in the load applied and each of the fed members is independently designed to accommodate its respective load as well as to accommodate a single feeding member. While the respective loads differ, only the design of the respective fed member is modified to accommodate the different load value while no modifications to the single feeding member are made.

摘要： A non-contact electric power transmission apparatus including a power supply unit and a load unit. The power supply unit has a first oscillation circuit, a signal secondary winding, a filter circuit, and a driving control circuit. The load unit has a power secondary winding, a signal primary winding, and a second oscillation circuit. The first oscillation circuit has a power primary winding and intermittently oscillates at a first oscillation frequency. When the load unit is placed at a predetermined position with respect to the power supply unit, since signals are induced in the power secondary winding by the signals in the power primary winding, the second oscillation circuit oscillates at a second oscillation frequency which is different from the first oscillation frequency. The signals from the second oscillation circuit are transmitted from the signal primary winding to the signal secondary winding. When the signals having the second oscillation frequency is input from the signal secondary winding to the driving control circuit through the filter circuit, the driving control circuit controls the first oscillation circuit to successively oscillates.
