Abstract: Various example embodiments relate to enhancing excitation and output power in multi-transmitter wireless power transfer system. Transmitter coils are arranged such that they are substantially uncoupled from each other. The transmitter coils are activated one by one to measure induced voltage across adjacent transmitter coils. The induced voltages are used to determine mutual inductance ratios of transmitter-receiver pairs to obtain current distribution coefficients indicative of the position of the receiver for optimal excitation. A device, a method, and a computer program are disclosed.
