A wireless power transfer system includes a power transmitting device and a power receiving device. When an abnormality occurs in the power transmitting device during power transmission to the power receiving device, the power transmitting devise stops power transmission. When power transmission is stopped, the power receiving device transitions to a sleep state which requires less power consumption than an operating state. When a first sleep time has elapsed since the transition to the sleep state, the power receiving device automatically starts up and sends the power transmitting device a request for resuming power transmission. When power transmission is stopped due to an abnormality in the power transmitting device, the power transmitting device resumes power transmission in response to receiving from the power receiving device a request for resuming power transmission as a trigger.
