不平衡电网下Y源双级矩阵变换器的无源滑模控制策略
Passivity-based Sliding-mode Control Strategy Based on Y-source Two-stage Matrix Converter Under Unbalanced Powr Grid
摘要
Abstract
Aiming at the shortcomings of the low-voltage transfer ratio of the two-stage matrix converter,the Y-source two-stage matrix converter(YSTSMC)is formed by embedding the Y-source network in the DC part,which has the characteristics of large voltage gain,few passive components,and low switching loss.If the grid voltage creates an un-balanced condition,the current and voltage will fluctuate greatly,affecting the power factor and power quality and reducing the reliability of system operation.In this paper,the input power control of the YSTSMC converter is studied for improvement of the input control of the YSTSMC converter.The traditional PI controller has the problems of relatively difficult parameter adjustment,low control accuracy,large overshooting amount,and poor anti-interference ability.Therefor,the YSTSMC control system based on the passivity based control-sliding mode control(PBC-SMC)under un-balanced grid condition is proposed,and its stability is proved.Simulation and experimental results show that the PBC-SMC control strategy based on passive and sliding mode theoretical foundations can lead to improved system re-sponsiveness and power quality.关键词
