CONDUCTIVE LAYER OF A LARGE SURFACE FOR DISTRIBUTION OF POWER USING CAPACITIVE POWER TRANSFER

摘要

An apparatus (300) for supplying power to a load in a capacitive power transfer system comprises a power generator (350) operating at a first frequency; a transmitter comprising a plurality of first electrodes (310) connected to a first terminal of the power generator (350) and a plurality of second electrodes (320) connected to a second terminal of the power generator (350) of a transmitter portion of the apparatus (300); and a plurality of inductors (340), wherein each inductor of the plurality of inductors is connected between a pair of a first electrode and a second electrode of the plurality of first and second electrodes, wherein each inductor comprises, together with a parasitic capacitor (330) formed between each pair of the first electrode and the second electrode, a resonant circuit at the first frequency in order to compensate for current loss due to parasitic capacitances.
