Document Type and Number:
Japanese Patent JP7368303
Kind Code:
B2
Abstract:
To provide a small-sized power supply device capable of outputting high power.SOLUTION: A power supply device comprises: a coil unit 10 including a first coil L1 and a second coil L2; a primary side circuit 20, which comprises a first capacitor C1 and a first switch circuit SW1, and in which the first capacitor C1 together with the first coil L1 constitutes a first resonance circuit; a secondary side circuit 30, which comprises a second capacitor C2 and a second switch circuit SW2, and in which a second capacitor C2 together with the second coil L2 constitutes a second resonance circuit; and a control part 40. The first coil L1 and the second coil L2 are fixed so as to face each other at a fixed distance D. The control part 40 controls the first switch circuit SW1 and the second switch circuit SW2 in such a manner that the coil unit 10 performs power transmission via magnetic field resonance.SELECTED DRAWING: Figure 1
