Abstract
The apparatus according to the invention is composed of one or plural generator devices (2) connected to an energy source and of one or plural loads (3) (which may be mobile). Each load is powered by the intermediary of a limited spatial zone (4) 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 (5) located on the surface of the generator and an electrode (6) or several sub-electrodes on the load side and located opposite. The active sub-electrodes (5) on the generator side are selected by switches (7), for example magnetic switches activated by a permanent magnet (8) located at the load (3). On the load side, a passive electrode (9) 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.
