<P>PROBLEM TO BE SOLVED: To provide a non-contact power supply device, suppressing the deterioration of a power factor even in a condition of a varied coupling state. <P>SOLUTION: The non-contact power supply device includes a secondary winding 201 to which power from an AC power supply is supplied from a primary winding 101. An impedance characteristic relative to a frequency Z1 has a minimum value in the vicinity of the frequency of a fundamental wave component of the AC power supply. An impedance characteristic relative to a frequency Z2 includes the frequency of the fundamental wave component between a frequency having a maximum value nearest the fundamental wave component frequency and a frequency having a minimum value nearest the fundamental wave component frequency. <P>COPYRIGHT: (C)2013,JPO&INPIT |
