Wireless power converters used as capacitive power transfer systems

摘要

The present invention relates to a DC-AC radio converter device (200) for supplying power to a load connected in a capacitive power transmission system. The device is coupled to at least two connectors (201, 202) and at least two connectors (201, 202) allowing galvanic contact to at least two supply lines (211, 212) of the DC grid, thereby A driver (203) that generates an AC power signal from a supplied input DC signal and at least a pair of transmission electrodes (204, 205) connected to the output of the driver, the frequency of the AC power signal being capacitive It approximately matches the series resonance frequency of the power transfer system.
