Principle and structure of wireless charger

Date:2017-11-30 Hits:0
The wireless charging system mainly adopts the principle of electromagnetic induction, and the energy transfer through the coil is realized by the coupling of energy. As shown in Figure 1, the input end of the system will transform the AC city electricity through the full bridge rectifier circuit into DC, or direct the power supply to the system with the 24V DC end. The DC power output through the power management module is converted to the primary winding through the 2M active crystal inverter to the high frequency alternating current. By coupling the energy through 2 inductors, the output current of the secondary coil is changed into direct current to charge the battery by the accepted conversion circuit.
