基于π型补偿网络的多负载CPT系统稳定性仿真分析

摘要

CPT system would work with the low efficiency or instability state under the circumstance of multi-loads or load changing. To solve the problem, additional circuit should be used in the primary loop in order to reduce the sensitivity of system' s load parameters for the primary loop. As a result, the overall performance of the CPT system would be upgraded. This paper analyzed the performances of CPT system theoretically when the π-type compensation network was added to the primary loop. And verified the result by MATLAB/Simulinkwhen all parameters changed.%CPT系统在多负载投切或负载变化寻情况下会出现系统工作效率低、工作不稳定的情况.针对该问题,可以通过在初级回路加入附加电路,降低系统对负载参数变化的敏感性,从而提升系统的整体性能.从理论上分析了在CPT系统中加入π型补偿网络进行参数调整后系统的各方面性能改变情况.通过MATLAB/Simulink进行仿真,对各个参数的改变情况进行了验证.
