S-S补偿IPT系统输出功率控制研究

Research on Output Power Control of S-S Compensated IPT System

由于输出功率受多种可变参数的影响,故串串(SS)补偿感应式电能传输(IPT)系统存在多种功率控制方式。为准确分析和确定IPT系统的最优控制方式,建立了系统的互感等效模型并基于模型得出系统的传输参数表达式,对比分析后得出采用移相控制来调节输出功率为系统的最优控制方式,接着搭建了实验平台,并用实验验证了移相控制的可行性。

Since the output power is affected by various variable parameters,there are multiple power control methods for the series-series(SS)compensated inductive power transfer(IPT)system.In order to accurately analyze and determine optimal control mode of the IPT system,an equivalent model of mutual inductance of the system is established and the expression of transmission parameters of the system is obtained based on the model,after comparative analysis,it is concluded that using the phase shift control to adjust the output power is the optimal control method of the system,then an experimental platform is built,and the experiment verifies the feasibility of phase shift control.
