<p>PROBLEM TO BE SOLVED: To provide a non-contact feeding method by which the threshold voltage of an inductor which causes an inductance transition is determined, in accordance with the value of a load current, a maximum load output obtained by a circuit system is secured and the fluctuations of a load terminal voltage can be reduced, even if the load current is varied significantly. SOLUTION: An inductor Lt whose inductance is changed in accordance with the value of a threshold voltage is connected between both the terminals of a load. When the load terminal voltage is larger than the threshold voltage, by utilizing the inductance transition of the inductor Lt , a resonance condition is deviated significantly, and the fluctuation of the load terminal voltage is suppressed. Furthermore, the threshold voltage of the inductor Lt is made to be approximately equal to the load terminal voltage at a load current value, corresponding to the maximum output of the load which is determined by a circuit system.</p> |
