Abstract:
Based on the series resonance compensation topology structure as the research foundation, taking charging electric cars as the object, using the simulation software to build a wireless charging system T model equivalent circuit, by dealing with choosing the right frequency sweep chopping frequency, using the method of regulating control, solves the problem of wireless power transmission efficiency is low and the rate of change, and finally the use of Ansoft electromagnetic simulation software Maxwell3D theory analyses the mutual inductance coil and the relationship between the transmission distance, to the study of wireless charging of electric cars, has very important significance.
