Simulink Simulation of Dual-Loop Rectifier Control

In this document, I provide a detailed description of a Simulink simulation for dual-loop rectifier control. The simulation implements an outer voltage loop and inner current loop design architecture, achieving highly satisfactory performance. The dual-loop rectifier represents a circuit control methodology that efficiently converts AC power to DC power, validated through this simulation. Key implementation aspects include: employing proportional-integral (PI) controllers for both loops with carefully tuned parameters to maintain DC output voltage stability and accuracy. The control strategy leverages cascade control principles where the inner current loop ensures fast dynamic response to load variations, while the outer voltage loop provides precise DC voltage regulation. This hierarchical design enables superior management of voltage and current during rectification processes, resulting in enhanced efficiency and performance characteristics. The simulation incorporates modeling of power electronics components (e.g., thyristors/IGBTs) and uses Simulink's Power Systems Library for accurate system representation. Overall, the simulation results demonstrate the feasibility and effectiveness of the dual-loop rectifier design, with waveform analyses confirming reduced ripple content and improved transient response.
