A contactless power supply is provided, which includes a main body; a primary circuit having a power input portion receiving main power, a switching circuit having a plurality of direct-current (DC) converter, and a primary transformer, which is disposed in one-side of the main body; and a secondary circuit having a secondary transformer which is disposed at a predetermined distance from the primary circuit and receiving power from the primary transformer contactlessly, a peripheral circuit which filters and rectifies the power, and a power supply unit supplying the rectified power to a control system. As described above, the contactless power supply has a long life span of use and a characteristic of non-occurrence of mis-operations as well as an efficient power transfer function even at the state of a low coupling coefficient and a large leakage inductance, due to a contactless power transfer, in which a load-side power supply control system is designed in various schemes so as to be adapted in various ways.
