Abstract: A contactless power supply system for transferring power without contact between a primary side coil and a secondary side coil is provided. In the contactless power supply system, a manipulation unit manipulates a secondary side converter so that power outputted to a load is controlled to be a command value. The manipulation unit manipulates an input voltage of a primary side resonance circuit so that a current flowing in the primary side resonance circuit equals a product of a current flowing in the secondary side resonance circuit and a current coefficient. The current coefficient is defined as a square root of a specific value and the specific value is an equivalent resistance of the secondary side resonance circuit divided by an equivalent resistance of the primary side resonance circuit.

Abstract: A contactless power supply device includes a power-transmitting-side pad and a power-receiving-side pad. Each of the power-transmitting-side pad and the power-receiving-side pad has a core and a coil. The core has a plate-shaped yoke portion. The coil has a first coil portion and a second coil portion. The first coil portion is arranged on a top surface of the yoke portion. The second coil portion is arranged along an outer periphery of the yoke portion.
