Wireless charging is derived from wireless power transmission technology.Wireless charging mainly uses electromagnetic induction, magnetic field resonance, radio wave technology principles. The square wave output of the active crystal oscillator of the wireless charger coil is filtered by the second-order low-pass filter to obtain the stable sine wave output. After passing the class C expansion circuit composed of triode 13003 and its peripheral circuit, it is output to the parallel resonant circuit composed of coil and capacitor, and radiated in to provide energy for the receiving part.
