|発明の名称||NON-CONTACT TYPE POWER FEEDING DEVICE|
PROBLEM TO BE SOLVED: To provide a non-contact type power feeding device having a mechanism for changing a capacitor capacity while suppressing an increase in switch elements.
SOLUTION: In a non-contact type power feeding device 10, a resonance capacitor 17 and a primary coil 18 are provided on an output side of a bridge circuit 16 including switches 11 and 13 and switches 12 and 14, and power is fed to a power receiving device 20 in a non-contact manner. Switches A and B respectively connected to positive and negative sides of a DC power supply portion 15, an auxiliary capacitor 24 having one side connected to the switches A and B and the other side connected to the resonance capacitor 17, a switch C provided on the switch 11 side between the switches 11 and 12, and control means 25 for switching between a high capacitor mode in which current is applied to the primary coil 18 via the resonance capacitor 17 and a low capacitor mode in which current is applied to the primary coil 18 via the auxiliary capacitor 24 and resonance capacitor 17 by controlling the ON and OFF states of each switch are provided.
