Abstract

These manuscripts present a closed-loop IGBT-based fourquadrant chopper drive system for DC motors. This paper intends to improve DC motor control’s accuracy, effectiveness, and adaptability in a variety of applications. In this paper, we build and put into practice a closed-loop control system that incorporates IGBT in order to manage the speed and torque of DC motors in both directions. A feedback system with sensors for measuring motor speed and current is used in the closed-loop control scheme to ensure perfect regulation of motor parameters. The IGBT-based chopper drive architecture allows for smooth switching between forward and reverse motor operation as well as dynamic braking, making it appropriate for applications requiring four-quadrant operation. The main benefits of our suggested system are greater motor protection through fault detection and quick responses to external disturbances, improved speed and torque management, and lower energy consumption. We show experimental data that demonstrate our design’s capacity to maintain stable motor functioning across a variety of operating situations, validating its usefulness in real-world applications. The presented system simulation result is verified in MATLAB/Simulink software. The demonstrated results are motor speed, torque, current and voltage.
