Abstract: An electromagnetic induction power transfer apparatus (100) comprises:an inductive power transmitter (102), comprising:a power supply with an active state and an inactive state, configured to switch between the active state and the inactive state at a selectable duty cycle; and a power-transmitting inductor (102-12) coupled to the power supply; and an inductive power receiver (104), comprising:a power-receiving inductor (104-12), positioned inductively proximate the power-transmitting inductor; a programmable load (104-12); and an impedance controller (104-6) coupled to the power receiving inductor and configured to increase or decrease an electrical impedance of the inductive power receiver in response to a change in a power requirement of the programmable load.

Abstract: A receiver device (404) in a coupled coil system (400) for wireless energy transfer includes a receiver coil (410) and a load device (414) operatively connected to the receiver coil and configured to receive a signal from the receiver coil. As one example, the load device is a rechargeable battery. An adjusting filter (416) is included in the receiver device and is operatively connected between the receiver coil and the load device. The adjusting filter can be used to transform the effective resistance or impedance of the load as presented to the transformer during energy transfer so that the effective resistant or impedance of the load is maintained at a substantially constant level, and the signal received by the load device is maintained at a substantially constant level.

Abstract: In an inductive energy transfer system, the phase of a signal that is applied to a transmitter coil to transfer energy is adjusted while energy is transferred from the transmitter device to a receiver device. The phase of the signal can be adjusted by changing a state of a DC-to-AC converter from a converting state to a non-converting state. The DC-to-AC converter outputs a signal that is applied to the transmitter coil when the DC-to-AC converter is in a converting state. A signal is not applied to the transmitter coil when the DC-to-AC converter is in a non-converting state.
