摘要
提出了一种基于模糊PI控制器的三相六开关PFC控制策略,该方法保证在负载突变的情况下动态响应快速,电流波形过渡平稳.根据三相六开关PFC在两相旋转坐标上的数学模型、SVPWM的调制策略和电流环前馈解耦策略,采用模糊规则表调整PI控制器参数.在MATLAB/Simulink中建立了仿真模型进行试验.结果显示三相六开关PFC的功率因数保持 0.99,抗干扰能力强,提高了输入电网电能质量.
Abstract
A three-phase six-switch PFC control strategy based on a fuzzy PI controller is proposed,which ensures fast dynamic response performance and smooth transition of current waveforms under sudden load changes.According to the mathematical model of the three-phase six-switch PFC in two-phase rotating coordinates,the modulation strategy of SVPWM and the current loop feed-forward decoupling strategy,a fuzzy rule table is used to adjust the PI controller pa-rameters.A simulation model is built in MATLAB/Simulink for testing.The results show that the three-phase six-switch PFC maintains a power factor of 0.99,has a strong anti-interference capability,and improves the power quality of the input grid.
