transferred from the primary coil to the secondary coil and ultimately to a load connected to the secondary side an example of a preferred embodiment of apparatus for wireless power transmittal according to the invention is shown in fig1 the apparatus 100 includes a number of primary coils 102 for transmitting power to a secondary side receiver not shown in fig1 a driver circuit 104 is coupled to the coils 102 preferably the driver circuit 104 is capable of adjustment in terms of frequency and amplitude in order to adjust transmission parameters suitable startup circuitry is provided in the driver circuit 104 in order to enable the apparatus 100 to achieve appropriate bias levels prior to driving the primary side coils 102 this preferably provides the capability for a smooth startup that mitigates or eliminates wasted energy and radiated emissions adjustable resistors may also be provided in order to regulate the amplitude of the transmitted signal for output at the primary side coils 102 the primary side coils 102 are preferably arranged so that they do not share the same plane it has been found that providing primary side coils in non coplanar configuration tends to provide favorable signal transmission coverage to a space in proximity to the primary side coils thus it may be anticipated that placement of one or receivers having secondary coil s in this proximity facilitates reception of the transmitted signal s in all or most secondary coil orientations as can be seen in the example of fig1 the primary coils 102 are non coplanar arranged around the periphery of a container 106 in this case box shaped.
