Abstract
A wireless power transmitting terminal and control method are disclosed. The wireless power transmitting terminal including an inverter circuit, a resonance circuit and a controller, wherein in a frequency detection state, an alternating current of the inverter circuit is controlled to switch between different candidate frequencies, so as to determine a resonance frequency and a maximum peak value of an electrical parameter of the alternating current at the resonance frequency, and determine an operating state of the power transmitting terminal according to the change of the maximum peak value. Therefore, the wireless power transmitting terminal can dynamically adjust in real time a preset operating state thereof, thereby improving the device adaptability, and avoiding the damage of the device to be charged.
