Abstract: The apparatus according to the invention is composed of one or plural generator devices connected to an energy source and of one or plural loads (which may be mobile). Each load is powered by the intermediary of a limited spatial zone where an electric field that is intense and rapidly varying is present, and this is achieved without wires or electrical contact or use of an earth connection. The intense field is created locally between certain sub-electrodes located on the surface of the generator and an electrode or several sub-electrodes on the load side and located opposite. The active sub-electrodes on the generator side are selected by switches, for example magnetic switches activated by a permanent magnet located at the load. On the load side, a passive electrode is used which can be considered as mainly coupled to the surrounding dielectric medium. The invention targets, in particular, the tele-supply of energy to low and medium power fixed or mobile electric devices.

Abstract: A capacitance (Cp) is a capacitance formed between a transmitting-device-side passive electrode and a receiving-device-side passive electrode. A capacitance (Ca) is a capacitance formed between a transmitting-device-side active electrode and a receiving-device-side active electrode. A bridge circuit formed by Z1 to Z4 is connected to a secondary side of a step-up transformer, where Z1 represents an impedance of a first element, Z2 represents an impedance of a second element, Z3 represents an impedance of a series circuit formed by the capacitance (Ca) and a load, and Z4 represents an impedance of the capacitance (Cp). By determining the impedances Z1 to Z4 such that this bridge circuit is balanced, a potential at a receiving-device-side reference potential point is made equal to a ground potential. This reduces variation in receiving-device-side reference potential, reduces noise, and stabilizes the operation of a load circuit on the receiving device side.

Abstract: A power transmission system is disclosed in which power is transmitted from a power transmission apparatus to a power receiving apparatus by electric field coupling between active and passive electrodes. The power transmission apparatus includes a step-up/down circuit for stepping up or down a direct voltage and an inverter circuit for converting the direct voltage into an alternating voltage that is output to the active and passive electrodes. The power transmission apparatus controls the step-up/down circuit to sweep a transformation ratio M=Vo1/Vin and detects the ratio M when an input power Pin of the step-up/down circuit is a minimum. The power transmission apparatus drives the step-up/down circuit to obtain the ratio M and perform the power transmission. As a result, there is provided a power transmission system capable of efficiently performing power transmission regardless of the change in a load in the power receiving apparatus.
