摘要

This study focuses on the development of a low-cost asymmetric converter for the switched reluctance motor (SRM), an electric motor that has gained significant attention due to its cost-effectiveness, energy efficiency, and simple design. Despite these advantages, the widespread adoption of SRMs is hindered by the high cost of the necessary driver converter, which adds complexity to the system and limits its application in various industries. The primary aim of this research is to reduce the cost of the converter while improving its performance. This study proposes a simplified asymmetric converter that minimizes the overall cost without compromising the motor's performance. The solution is achieved by simplifying the electronic circuitry, optimizing key components (such as MOSFETs and Schottky diodes), and implementing an efficient hysteresis current regulation control strategy. This study utilizes Altair Flux2D software for simulating the motor and converter behavior, employing finite element analysis (FEA) for accurate modeling. The simulation results are validated through real-world experiments, confirming that the proposed approach significantly improves both control accuracy and energy efficiency. The performance of the converter is proved to be effective, offering a practical solution for SRM applications, particularly in electric vehicles, industrial automation, and renewable energy systems. In conclusion, this study provides an innovative approach for reducing the cost and improving the effectiveness of electronic components in SRM converters. These findings contribute to the broader adoption of SRMs across various sectors, where cost reduction and performance optimization are critical priorities.
