摘　　要：日常生活中交流电能大多数来自电网,因而整流电路是电网和电力电子装置的接口电路,其性能将影响电网的运行和电能质量。为了简化分析和控制Vienna整流器的过程,定义一个与开关管工作状态相关的新中间变量。采用动力学方法中的拉格朗日方程建立Vienna整流器的数学模型,再通过双闭环控制实现对整流器的准确控制。最后通过Matlab/Simulink搭建整流器的仿真模型,并利用HIL平台进行实验验证,结果表明所提控制方法较好地抑制了Vienna整流器直流侧中点电压波动与电流过零畸变的问题,实现了整流器在单位功率因数下运行,说明了控制方法的有效性和鲁棒性。Most of the alternating current used in daily life comes from the power grid,making the rectifier circuit the interface between the power grid and power electronic devices.Its performance will affect the operation of the power grid and the quality of electric energy.In order to simplify the process of analyzing and controlling the Vienna rectifi-er,an intermediate variable related to the operating state of the switching tube is proposed.Establish a mathematical model of the Vienna rectifier by using dynamic method,and achieve precise control through dual closed-loop strategy.Finally,using Matalb/Simulink simulation to build the simulation model and conducting experimental verification through HIL.The results show that the fluctuation of neutral point voltage and zero-crossing distortion of current is suppressed and unit power operation is achieved,demonstrating the effectiveness and robustness of the control method.
