An inductive or wireless power transfer coupler array has at least two coupler modules connected in parallel to a common power source. Each coupler module comprisesa resonant circuit, including at least one transmitter coil and a capacitive element. Each of the coupler modules is connected to a second terminal of the power source across the respective resonant circuit by a corresponding pair of switching elements,and each coupler module is linked with at least one other coupler module at a shared one switching element of the corresponding pair of switching elements. A control module is configured to effect control between the active state and the passive state by controlling the phase angle of the corresponding pair of switching elements.
