PROBLEM TO BE SOLVED: To provide a non-contact power transmission device capable of appropriately detecting an abnormality in a frequency of AC power that is transmitted from power transmitting equipment to power receiving equipment in a non-contact state, and the power receiving equipment.SOLUTION: Power transmitting equipment 11 comprises an AC power source 12 capable of outputting AC power using a power transmission side clock signal CK1, and a power transmitter 13 to which AC power is inputted. Power receiving equipment 21 comprises a power receiver 23 capable of receiving AC power that is inputted to the power transmitter 13, in a non-contact state and a rectifier 24 to which AC power that is received by the power receiver 23 is inputted. The power receiving equipment 21 comprises a microcomputer 26 for power reception side control including a power reception side clock circuit 27 that outputs a power reception side clock signal CK2, and a power reception side frequency detection part 42 for detecting a frequency of AC power from the power receiver 23 to the rectifier 24 using the power reception side clock signal CK2.SELECTED DRAWING: Figure 1 |
