Abstract | The present invention relates to a method for implementing frequency adjustment based on tracking power, comprising the following steps: (1) a wireless charging transmitting end operates according to an initial frequency preset by the system; and (2) the wireless charging transmitting end implements successive approximation adjustment of the frequency on the basis of a charging power acquired in real time, the successive approximation adjustment implementing adjustment on the basis of a progressively calculated frequency error compensation value and stepped frequency value circulation, and adjusting in the opposite direction to the previous time until the acquired charging power reaches the required power. Using the present method for implementing frequency adjustment based on tracking power does not increase hardware costs, and uses an algorithm to enable the transmitting end to implement conversion from a fixed frequency to a variable frequency; the influence of temperature is avoided, compatibility and ada |
