Analysis of the Theory ofWireless Power Transferand the Design of the Product
AbstractIn order to study the wireless transfer circuit mechanism of inductive coupling.This passage established the circuit model of the wireless energy transfer systemabout inductive coupling . Analyzed the relationship between the efficiency of thissystem and mutual inductance of two coils(circular ,equilateral triangle , squarecoils) ,as well as the relationship between efficiency and the load was given too,which can provide the theoretical basis for the design and energy optimization of thesystem.A inductive mode of wireless power transmission system equipment wasdesigned to verify the theoretical analysis. The equipment can charge your phones andso on.
