  "textContent": "A power control device includes a power receiving unit, a power converting unit, and a control device. The power receiving unit includes a secondary coil that receives AC electric power transmitted from a power transmitting device in a non-contact manner. The power converting unit includes transistors with two phases as a pair connected to the secondary coil. The power converting unit converts the AC electric power received by the power receiving unit to DC electric power. The control device performs a synchronous rectification operation of rectifying the AC electric power by synchronously driving the transistors in two phases when a target output is equal to or greater than a target output. The control device controls the synchronous rectification operation and a short-circuiting operation of short-circuiting the secondary coil using the transistors in two phases through pulse frequency modulation when the target output is less than the predetermined value.",
