Reducing Power Dissipation in Inductive Energy Transfer Systems |
| 摘要 |
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. |

1. A transmitter device for an inductive energy transfer system, comprising:
a DC-to-AC converter operably connected to a transmitter coil; and a controller operably connected to the DC-to-AC converter and configured to transmit one or more signals to the DC-to-AC converter to change a state of the DC-to-AC converter between a converting state and a non-converting state when the transmitter coil is transferring energy. |
