Title:
NON-CONTACT POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/042353
Kind Code:
A1
Abstract:
The capacitance in a resonance-type changeover circuit (41) of a secondary coil (L2) is varied by changing over the effective capacitor in accordance with the position thereof with respect to a primary coil (L1). The position of the resonance system with respect to the operating frequency is kept constant by means of this variation in capacitance. In this way, better stability of the output of powered equipment (30) can be achieved, irrespective of the position of the secondary coil (L2).
