“…According to the above theoretical derivation and comparative analysis in the paper, the fluctuation of the efficiency curve is more obvious with the change of mutual inductance. Therefore, it is necessary to quickly estimate M to adapt to the change of coupling mutual inductance [9]. In Equation ( 2), the series impedance R p and R s of the coil are generally much smaller than the secondary equivalent impedance R eq and the mapped impedance from the secondary side to the primary Z r .…”

Magnetic coupling resonant wireless energy transmission technology has become an important research direction for electric vehicle wireless charging systems. This paper proposes an efficiency optimization strategy for the electric vehicle wireless energy transmission system based on LCL-S topology to improve the efficiency of electric vehicle magnetic coupling resonant wireless charging. This paper analyzes the optimization method of system efficiency based on LCL-S topology, establishes an experimental model in MATLAB/Simulink simulation software, and verifies it with the control variable method. The experiment shows that the efficiency optimization strategy based on the LCL-S topology proposed in this paper can effectively improve the system transmission efficiency and stabilize the transmission efficiency at a higher level faster.
