NON-CONTACT CHARGING DEVICE AND NON-CONTACT CHARGING METHOD

摘要

A non-contact charging apparatus configured to, using variable information for varying the inductance and the capacitance of a matching unit for matching the impedance of a power supply system associated with a combination of the first distance representing the length of a line segment connecting the position of the center point of a power transmitting resonance coil and the position of the center point of a power transmitting resonance coil and the second distance that is the distance between the plane having the power transmitting resonance coil and the plane having the power receiving resonance coil and the impedance of a power transmitting/receiving system that changes according to the relative positions of the power transmitting resonance coil and the power receiving resonance coil, vary the inductance and the capacitance of the matching unit for matching the impedance of the power supply system that supplies alternate current power and the impedance of the power transmitting/receiving system including a power transmitting unit and a power receiving apparatus according to the variable information.
