A wireless power transfer system for a vehicle traveling along a surface is provided. The wireless power transfer system includes a receiver coil mounted to the vehicle; a plurality of transmitter units connected in series and positioned on the surface; and a controller in communication with voltage sensors of each transmitter unit. The transmitter units include inactive and active transmitter units, and the inactive transmitter units include a leading transmitter unit and a trailing transmitter unit adjacent to the active transmitter units. The controller is configured to receive voltages of the leading and trailing transmitter units, compare the voltages with data in the database, and determine a position of the receiver relative to the transmitter units in order to activate and deactivate transmitter units as needed to dynamically modify the subset of active transmitter units to provide an efficient and smooth power supply to the receiver.
