PROBLEM TO BE SOLVED: To provide a power supply system which can supply enough power with small electrodes. SOLUTION: In this system, a terminal unit 2 contains electrodes S3 and S4, load RL which is connected to the electrodes S3 and S4 and a capacitor C which is connected between the electrodes S3 and 84. A body system 1 is provided with electrodes S1 and S2 which confront with the electrodes S3 and S4 of the unit 2 respectively, a variable frequency oscillator OSC, a tuning coil L which is electranagnetically connected to the oscillator OSC and also connected to the electrodes S1 and 82 and a control circuit A. High voltage can be induced to a tuning circuit even without making the electrodes S1 to S4 so large by controlling the oscillation frequency of the oscillator OSC so that it may coincide with the tuning frequency of the tuning circuit that comprises the capacitor C, the coil L, the interelectrode capacitance of the electrodes S1 and S3 and the interelectrode capacitance of the electrodes S2 and S4 by the circuit A. |
