Claim 18:
19. A method for wireless power transmission by a wireless power transmission apparatus, comprising:
managing connections, via a plurality of switches, between a plurality of primary coils and respective local controllers including at least a first local controller and a second local controller;
determining that a first primary coil of the plurality of primary coils is providing wireless power to a first wireless power receiving apparatus;
operating, by a master controller, a state of the plurality of switches such that one or more adjacent primary coils near the first primary coil remain uncoupled from its respective local controller while the first primary coil is providing the wireless power to the first wireless power receiving apparatus; and
disabling, before changing the state of plurality of switches, the first local controller to prevent current from traversing from the first local controller via the plurality of switches while the state of plurality of switches are changed, and
enabling the first local controller after the state of the plurality of switches has changed to couple one or more primary coils of plurality of primary coils to the first local controller.
