摘要
Abstract
The single-phase cascaded H-bridge rectifier is taken as the object of study,and its control strategy is studied.Firstly,based on the double closed-loop control strategy,the dq feed-forward decoupling model is constructed,and the influence of the virtual AC component on the system is improved by the second-order generalized integral algorithm,the fast and accurate tracking of grid-side current to voltage phase and frequency is realized.Secondly,the traditional voltage balancing control algorithm is improved by defining the power balancing relationship,the output voltage square is taken as the control signal to enhance the adaptive ability of the system and improve the dynamic performance of the system during load switching.Finally,simulations based on MATLAB/Simulink software are performed to verify the correctness and effectiveness of the proposed strategy.关键词
