Wireless power transmission apparatus with multiple primary coils and adjacent coil muting

A wireless power transmission apparatus, comprising:

• a plurality of primary coils organized into at least a first group of primary coils and a second group of primary coils;
• at least a first local controller associated with at least the first group of primary coils and a second local controller associated with at least the second group of primary coils;
• a plurality of switches capable of individually coupling the first local controller to one or more primary coils of the first group of primary coils and individually coupling the second local controller to one or more primary coils of the second group of primary coils;
• and
• a master controller configured to:
• operate the plurality of switches to control which one or more primary coils of the first group of primary coils is coupled to the first local controller and which one or more primary coils of the second group of primary coils is coupled to the second local controller,
• disable, before changing a 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
• enable the first local controller after the state of the plurality of switches has changed to couple the one or more primary coils of the first group of primary coils to the first local controller.
