PROBLEM TO BE SOLVED: To provide a non-contact power transmission device without need of adding a constant voltage control circuit, compatible with a wide input voltage, to the power reception side.SOLUTION: Fifth to eighth switch elements 20-23 are connected in parallel with each of first to fourth diodes 12-15 constituting a rectifier circuit on the power reception side of the non-contact power transmission device. In synchronization with a signal to alternately switch on and off a set of first to fourth switch elements 3, 6 on the power transmission side and a set of second and third switch elements 4, 5, a set of the fifth and the sixth switch elements 20, 21 and a set of the seventh and the eighth switch elements 22, 23 are alternately switched on and off.SELECTED DRAWING: Figure 1 |
