A power-receiving device includes a secondary-side coil which can receive a first alternating current power without contact from a power-sending device having a primary side coil into which first alternating current power is input. The power-receiving device comprises a first power transmission path, a second power transmission path, a common path positioned in common with the first and second power transmission paths, and a voltage regulator arranged on the common path. The voltage regulator rectifies the first alternating current power received by the secondary coil or the second alternating current power from a connecting portion, converts the rectified power to a predetermined specific voltage value, and outputs the power.

Power-receiving device and power transmission system

A non-contact power transmission device equipped with a ground-side device and a vehicle-side device. The ground-side device has a primary-side coil to which alternating-current power is input. The vehicle-side device includes a secondary-side coil, a battery, a secondary-side matching device, and a charging device. The secondary-side coil receives alternating-current power from the primary-side coil in a non-contact manner. The secondary-side matching device is provided between the secondary-side coil and the battery, and has a predetermined fixed inductance and fixed capacitance. The charging device has a switching element that performs a switching operation with a prescribed cycle. The charging device adjusts the duty ratio of the switching operation in accordance with the impedance of a load.

Non-contact power transmission device

A contactless power transmission device includes a switching unit that switches a power transmission line so that a first power is transmitted through the first line when an AC power supply outputs a first AC power and so that a second power is transmitted through a second line when the AC power supply outputs a second AC power. An impedance conversion unit is arranged on the second line that converts an impedance from an output of the AC power supply to a variable load when the second power is transmitted through the second line to approach an impedance from the output of the AC power supply to the variable load when the first power is transmitted through the first line.
