REDUCING POWER DISSIPATION IN INDUCTIVE ENERGY TRANSFER SYSTEMS

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...

Zusammenfassung: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.
