Claim 17:
18. An apparatus comprising:
at least one disconnect coupled to a current loop that provides power from a power transmitter coupled to the current loop, wherein the power transmitter provides alternating current (AC) power to the current loop; and
a controller coupled to the at least one disconnect, wherein the controller is configured to control the at least one disconnect to periodically disconnect from the current loop for a period of time, wherein the controller disconnects from the current loop to stop pulling power for multiple different periods of time that encompass corresponding multiple different portions within one period of an AC waveform of the AC power, wherein the multiple different portions of the AC waveform include a first portion that encompasses a zero crossing of the AC waveform and a second portion that encompasses a peak of the AC waveform.
