A power supply system comprises a first node connected to a second node via an electrically conducting cable, wherein the cable is conducting alternating current at high frequency (e.g. 100Hz or higher, e.g. 20KHz or higher) between the first and second nodes, and the electrically conducting cable is a capacitive cable. A power supply at the high frequency can be connected to the first node, or a power supply at 50 or 60Hz can be connected to a converter outputting power at the high frequency with the converter output connected to the first node. A converter can be connected to the second node, or an electrical appliance operating using high frequency power can be connected to the second node. A related wireless electric vehicle charging system comprises (a) a power supply, optionally a power supply system of the invention, (b) an inverter connected to the power supply and adapted to output power at a high frequency, e.g. 1kHz and above, and (c) a plurality of wireless charging stations, each comprising at least one transmitter, wherein the inverter is connected to each of the plurality of wireless charging stations using a capacitive cable.
