Practical new content of wireless charger
In view of the shortage and limitation of the existing technology, the utility model is to solve the technical problem by providing a wireless charging transmitter and a wireless charging device. The power transmission coil and the receiving coil are used as communication coils to solve the shortcomings of small output power, short vertical transmission distance of electric quantity, and large power consumption of feedback data coding and modulation modulation.
The technical scheme of the utility model is that:
A wireless charging transmitter, including the PWM pulse generator 1, the driving circuit, the resonant transmitting circuit, the PPM decoding circuit and the power supply circuit, the PWM pulse generator 1, the driving circuit and the harmonic emission circuit are connected in turn; the resonant transmitting circuit is connected with the signal feedback end of the PWM pulse generator 1 through the PPM decoding circuit, and the PWM pulse is used. The impulse generator 1 and the driving circuit are connected with the power supply circuit.
