Abstract
A power receiving device that receives electric power output from a power transmission device includes a primary side coil and supplies electric power to a load according to the electric power. The power receiving device includes: an adjusting device that adjusts a value of a third current to be a predetermined value, the third current is generated from the second current and supplied to the load; a detecting device that detects the third current; and a variable capacitor coupled between the secondary side coil and the load. The variable capacitor ensures a changeable capacitance value. The adjusting device performs an adjustment based on a detection result by the detecting device. The variable capacitor is coupled in series with the secondary side coil and the load. The adjusting device includes a first adjusting device that increases the capacitance value and a second adjusting device that decreases the capacitance value.
