Abstract
A contactless power supplying device includes a plurality of unit controllers that control a plurality of groups of power supplying unit circuits, which respectively excite a plurality of groups of primary coils. A clock signal generation circuit provides the plurality of unit controllers with a common clock signal. The plurality of unit controllers generates synchronization signals to excite the plurality of groups of primary coils in accordance with a common clock signal and provides the synchronization signals respectively to a plurality of power supplying unit circuit. The synchronization signals are rectangular wave pulses having the same cycle, and the plurality of groups of primary coils are excited with the same frequency.
