  "textContent": "A contactless power feeding system includes: a power converter which converts DC power from a DC power supply, to AC power; a power transmission electrode to which AC power converted by the power converter is applied; a power reception device having a power reception electrode, receiving power through capacitive coupling between the power transmission and reception electrodes, and feeding power to a load; a voltage detection unit which detects voltage of the power transmission electrode; and a control unit which controls the DC power supply or the power converter using voltage detected by the voltage detection unit. The voltage detection unit has a voltage detection electrode and detects voltage of the power transmission electrode through capacitive coupling between the power transmission electrode and the voltage detection electrode.",
