Abstract
A direct current (DC) to alternating current (AC) wireless converter apparatus (200) for supplying power to a load connected in a capacitive power transfer system. The apparatus comprises at least two connectors (201, 202) enabling a galvanic contact to at least two supply lines (211, 212) of a DC grid; a driver (203) coupled to the connectors (201, 202) and configured to generate an AC power signal from an input DC signal fed by the at least two connectors, wherein a frequency of the AC power signal substantially matches a series-resonance frequency of the capacitive power transfer system; and at least a pair of transmitter electrodes (204, 205) connected to an output of the driver.
