Abstract
Systems and methods for tuning power transmission circuits may sweep a power frequency applied to a transmission coil across a plurality of frequencies. The transmission coil may be inductively coupled to a receiving coil and separated from the receiving coil by an air gap. A current and/or voltage at the transmission coil may be measured in response to the power frequency being at each frequency of the plurality of frequencies. A transmission frequency may be selected based at least in part on the measured current and/or the measured voltage.
Claims13
A power transmission system for an aircraft, comprising:
- a power transmission circuit, comprising:
- a transmission coil;
- a receiving coil inductively coupled to the transmission coil, wherein the receiving coil is separated from the transmission coil by a variable air gap defined by the receiving coil and the transmission coil;
- wherein the power transmission circuit is configured to sweep a power frequency applied to the transmission coil and measure at least one of a voltage or a current in response to the sweep, wherein the power transmission circuit is configured to select a transmission frequency for the transmission coil in response to the voltage or the current.
The power transmission system of claim 8, further comprising a hubcap with the receiving coil disposed on the hubcap.
A wheel assembly for an aircraft, comprising:
- an axle;
- a wheel coupled to the axle and configured to rotate about the axle;
- a transmission coil disposed in the axle;
- a hubcap mounted on the wheel with a receiving coil of the hubcap adjacent the transmission coil disposed in the axle, wherein the transmission coil is separated from the receiving coil by a variable air gap defined by the receiving coil and the transmission coil;
- and
- a power transmission circuit configured to transmit power from the transmission coil to the receiving coil, wherein the power transmission circuit is configured to select a transmission frequency in response to at least one of a voltage or a current of the transmission coil.
