First Claim
1. Apparatus comprising:
- an induction coil arrangement, the induction coil arrangement having a first set of at least one coil with a first diameter and a second set of at least one coil with a second diameter, the second diameter being different to the first diameter, a first tap connected at a first end of the first set, a second tap connected at connection common to a second end of the first set and a first end of the second set, and a third tap connected at a second end of the second set;
a power transmit arrangement selectively connectable to a first combination of two of the first to third taps; and
a power receive arrangement selectively connectable to a second combination of two of the first to third taps, the second combination being different to the first combination.

7. A method of operating apparatus comprising:
-
an induction coil arrangement, the induction coil arrangement having a first set of at least one coil with a first diameter and a second set of at least one coil with a second diameter, the second diameter being different to the first diameter, a first tap connected at a first end of the first set, a second tap connected at connection common to a second end of the first set and a first end of the second set, and a third tap connected at a second end of the second set; a power transmit arrangement; and a power receive arrangement, the method comprising; in response to receiving a user input indicating that power transmission is required; a) connecting the power transmit arrangement to a first combination of two of the first to third taps; b) operating the power transmit arrangement; and c) refraining from activating the power receive arrangement. - View Dependent Claims (8, 9, 10, 11, 12)
