doi:10.11985/2022.04.020

Abstract

Abstract:

Bilateral LCL compensation method is the most common compensation method for wireless power transmission systems, and is a research hotspot in this field. However, with the change of operating conditions, the constant current characteristics vary with the system parameters and loads, which brings many difficulties to practical application and control. From the perspective of actual parameters and influence characteristics, the influencing factors of the constant current output characteristics of the LCL compensation network system are studied in detail. The actual circuit parameter model of the bilateral LCL compensation network is established, and the load parameter constraints for the constant current output design of the system are given. The influence of loss parameters on the system is analyzed as well. Considering the loss parameters of components, a design scheme of bilateral LCL compensation network wireless power supply system is proposed. The simulation and experimental results prove the effectiveness of the scheme. The system output current fluctuation rate reaches the preset design requirement of no more than 10%, and has a good filtering effect on high-order harmonics, which is consistent with the theoretical design.
