1. A wireless power receiving apparatus configured to receive an electric power signal including any one of an electric field, a magnetic field, and an electromagnetic field, transmitted from a wireless power supply apparatus, the power receiving apparatus comprising:
a reception coil configured to receive the electric power signal; a capacitor arranged such that a first terminal thereof is set to a fixed electric potential; a first switch and a second switch sequentially connected in series so as to form a closed loop together with the reception coil, and arranged such that a connection node that connects the first and second switches is connected to a second terminal of the capacitor; a third switch and a fourth switch sequentially arranged in series so as to form a path arranged in parallel with a path comprising the first and second switches, and arranged such that a connection node that connects the third and fourth switches is set to a fixed electric potential; and a control unit configured to control the first switch through the fourth switch, wherein the control unit is configured to be capable of switching states between a first state in which the first switch and the fourth switch are on and the second switch and the third switch are off, and a second state in which the first switch and the fourth switch are off and the second switch and the third switch are on, and wherein the control unit controls a switching timing at which the state is switched between the first state and the second state such that the amplitude of a current that flows through the reception coil approaches a maximum value. |
