WIRELESS POWER TRANSMITTING DEVICE AND METHOD FOR CONTROLLING TO TRANSMIT WIRELESS POWER SIGNAL IN WIRELESS POWER TRANSMITTING DEVICE

摘要

A wireless power transmitting device for controlling transmission of a wireless power signal. The wireless power transmitting device comprises a direct current sensor, an alternating current sensor, and an alternating voltage sensor. The wireless power transmitting device further comprises a transmission coil configured to transmit a wireless power signal to a wireless power receiving device, receive a wireless power receiving signal from the wireless power receiving device through the transmission coil, and transmit a request signal to the wireless power receiving device for requesting wireless power information from the wireless power receiving device by receiving at least two of a direct current signal, an alternating current signal, and an alternating voltage signal of the transmission coil. The wireless power transmitting device additionally comprises a wireless power transmitting controller configured to perform signal processing to indicate a reception state error when at least two of the direct current sensor, the alternating current sensor and the alternating voltage sensor are in an error state. The wireless power transmitting controller is further configured to control the wireless power signal on the basis of the wireless power receiving signal.
