Simulation Design of Three-Phase PWM Rectifier System Using MATLAB

In this article, we explore the simulation design of a three-phase PWM rectifier system using MATLAB. We examine how this technology is implemented, its advantages, and application areas. We delve into various algorithms and techniques used in this domain, such as current control and voltage control strategies, and discuss their performance under different operating conditions. The implementation typically involves MATLAB/Simulink models with key functions like PWM signal generation using Space Vector Modulation (SVM) techniques and PI controller blocks for closed-loop regulation. We also analyze the relationship between rectifiers and other power electronic components, highlighting their roles within electrical circuits. Furthermore, we address potential challenges in practical applications, such as harmonic distortion and switching losses, and provide solutions including filter design optimization and advanced modulation techniques. Through code examples, we demonstrate how to configure subsystem blocks for voltage balancing and implement dq-transform based control algorithms for decoupled active/reactive power regulation. This article provides a comprehensive understanding of MATLAB-based three-phase PWM rectifier simulation design and methodologies for achieving optimal performance in real-world applications.
