ISOMOTOR CONTROL: HIGH-PERFORMANCE DC MOTOR SPEED CONTROL WITH ISOLATION TECHNOLOGY

Abstract

Precise control of DC motor speed is critical in industrial automation, electric vehicles, and renewable energy systems, where performance, reliability, and efficiency are paramount. Conventional control methods often suffer from power losses, instability, and limited flexibility in handling varying load conditions. This study presents an isolated DC–DC converter–based approach for optimizing DC motor speed with enhanced control and efficiency. By incorporating galvanic isolation, the proposed system improves safety, minimizes electromagnetic interference, and ensures stable voltage regulation across different operating ranges. Simulation and experimental analysis demonstrate that the converter-based design achieves superior speed regulation, reduced total harmonic distortion (THD), and improved energy efficiency compared to traditional techniques. The findings highlight the potential of isolated DC–DC converter architectures as a reliable and scalable solution for modern motor drive applications, contributing to advancements in smart energy systems, automation, and sustainable transportation.
