Analysis and Performance Evaluation of a Full-Wave Three-Phase Uncontrolled Rectifier in Driving a Single-Phase DC Motor

Abstract

This study examines the design and performance of a full-wave three-phase uncontrolled rectifier in driving a single-phase DC motor, focusing on its practical application in industrial settings. The three-phase DC motor is widely adopted in industry due to its operational simplicity and efficiency. However, challenges arise when converting the electrical power source, as most of the power grid in Indonesia relies on alternating current (AC). To address this issue, a rectifier circuit is essential to convert the AC input into a stable DC output using diodes, enabling compatibility with DC motor requirements. The need for robust and high-capacity DC power sources in industrial applications necessitates the use of three-phase rectifiers, which can provide higher power output compared to single-phase systems. This paper analyzes the working principles, circuit topology, and diode configuration of the three-phase uncontrolled rectifier. By integrating these components, the rectifier ensures efficient energy conversion and supports the operational demands of single-phase DC motors in industrial environments. Furthermore, this research highlights the system's performance metrics, including power efficiency, voltage regulation, and thermal characteristics, based on experimental evaluation. The findings contribute to the optimization of rectifier systems in engineering applications, emphasizing their role in enhancing the reliability and scalability of DC motor systems for industrial automation and energy systems.
