A: Yes. The wireless charger is launched on the same principle as the induction cooker. Wireless charging technology is the use of electromagnetic induction principle, in the sending and receiving end with the corresponding coil to send and receive inductive current to charge. It works by using magnetic fields! Close is similar to the transformer, the transmitter has a coil, the receiver has a coil, the capacitor on the coil in parallel, so that the resonant frequency of the two coils is the same, the sending end has an oscillator, amplifying circuit, and the final switching circuit, the high-frequency pulse electricity is added to the transmitter coil, when the receiving coil is close, it will induce a current, and then through the rectifier filter circuit to the battery charging.
