Modeling and Simulation of AC Power Controller with MATLAB and Proteus Integration

Abstract

This article explores the design and simulation of an AC power controller using MATLAB and Proteus. The integration of MATLAB for control algorithm development and Proteus for hardware simulation provides a comprehensive model approach and analyzes the performance of the AC power controller. The paper discusses the methodology for building the system, including the simulation of AC circuits, power control techniques, and the interaction between MATLAB's control models and Proteus' hardware simulation environment. Results demonstrate the effectiveness of the proposed system in managing AC power with enhanced precision and reliability. The AC voltage controller typically employs phase control techniques, where the triggering of a Triac or SCR (Silicon Controlled Rectifier) is controlled to vary the conduction angle, thus controlling the effective voltage supplied to the load. This simulation uses MATLAB to design the control algorithm, particularly for generating the gate trigger signals for the SCRs or Triacs, based on the input AC waveform and the desired output voltage. Proteus is used for the hardware simulation, where the AC source, SCRs/Triacs, and load are modeled to demonstrate the effectiveness of the voltage regulation.
