Abstract
A wireless electric power receiving device and a wireless electric power transmission system are disclosed. The wireless electric power receiving device is coupled to a wireless electric power transmitting device, and comprises a receiving coil, a power supply circuit and an alarm unit. When the receiving coil is coupled, a coupling voltage is generated and outputted. The power supply circuit comprises a first receiving terminal coupled to the receiving coil, and compares the voltage with a preset operation voltage range to generate and output a control signal when the voltage is beyond the range. The alarm unit is electrically coupled to the power supply circuit to receive the control signal from the power supply circuit and to output an alarm signal according to the control signal. The device can prevent a user from misusing a household appliance in case of a deficient voltage.
