The invention provides a resonance compensation method, device and system for a wireless charging transmitting coil, and relates to the technical field of electronic circuits. The resonance compensation method specifically comprises the following steps: S1, measuring to obtain a total inductance value of a primary coil or a secondary coil, a first inductance value of a first winding wire, a second inductance value of a second winding wire and a mutual inductance value between the first winding wire and the second winding wire; S2, according to the values measured in the step S1, respectively processing to obtain capacitance values of the first capacitor and the second capacitor; and S3, setting a first capacitor and a second capacitor to form a resonance compensation device. The beneficial effects of the technical scheme are that according to the incoming resonance compensation method, device and system of the wireless charging transmitting coil, the coil circuit has stronger current-carrying capability, the
