摘要： An automatic tuning assist circuit is coupled with a transmission antenna. The transmission antenna injects a first correction current into, or otherwise draws the first correction current from, the transmission antenna. In the first state, the first auxiliary coil is coupled with the transmission antenna. In this state, the first correction current IA, which corresponds to a current that flows through the first auxiliary coil, is injected into or drawn from the transmission antenna. In the second state, the first auxiliary coil is decoupled from the transmission antenna. In this state, the current that flows through the first auxiliary coil flows through a current path which is independent of the transmission antenna. The state is switched between the first state and the second state with the same frequency as that of the driving voltage.

摘要： An automatic tuning assist circuit is coupled in series with a transmission antenna. A first switch and a second switch are arranged in series between a first terminal and a second terminal of the automatic tuning assist circuit. Furthermore, a third switch and a fourth switch are arranged in series between the first terminal and the second terminal. A first auxiliary capacitor is arranged between a connection node that connects the first switch and the second switch and a connection node that connects the third switch and the fourth switch. A control unit switches the first switch through the fourth switch with the same frequency as that of the driving voltage, and with a predetermined phase difference with respect to the driving voltage.

摘要： A wireless power transmitting apparatus transmits an electric power signal comprising any one from among an electric field, a magnetic field, and an electromagnetic field to a wireless power receiving apparatus. A reflector coil is arranged at a distance from a radiation coil. A driving power supply supplies a driving current to the radiation coil. A first phase control circuit controls the phase of the current that flows through the reflector coil so as to stabilize, to a predetermined value, the phase difference between the current that flows through the reflector coil and the current that flows through the radiation coil.

摘要： A wireless power transmitting apparatus transmits an electric power signal comprising any one from among an electric field, a magnetic field, and an electromagnetic field to a wireless power receiving apparatus. A transmission antenna includes a transmission coil. An automatic tuning assist circuit is coupled in series with the transmission antenna. A power supply applies an AC driving voltage across both terminals of a series circuit that comprises the transmission antenna and the automatic tuning assist circuit. A first controller switches on and off multiple switches in synchronization with the driving voltage. A voltage monitoring unit monitors the voltage that develops at an auxiliary capacitor.

摘要： A measurement auxiliary circuit is configured to form a resonance circuit together with a detection target. An ATAC is coupled with the resonance circuit. A signal generator applies an AC probe signal VS to the resonance circuit. After the impedance measurement apparatus enters a stable state, an impedance detection unit measures a voltage at at least one node and/or a current that flows through at least one current path. The impedance detection unit detects the impedance of the detection target based on the measurement value.
