15W wireless charging coil  

15W wireless charging coil Wireless charging coil wireless charging system firstly selects electromagnetic induction principle to end energy transmission through intermittent energy coupling of coils. When the system works, the input converts AC mains power into DC power through a full-bridge rectifier circuit, or directly supplies the system with 24V DC power. The output DC power is converted into high-frequency AC power through a 2M active crystal inverter after passing through the power processing module and supplied to the primary side winding. Through the coupling energy of the two induction coils, the receiving conversion circuit converts the current output from the secondary coil into DC power to charge the battery.
