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

Abstract

This research investigates the design and performance of a full-wave three-phase uncontrolled rectifier used to drive a single-phase DC motor, with a particular focus on its practical application in industrial environments. Three-phase DC motors are widely utilized in industry due to their ease of operation and efficiency. However, challenges arise in converting the power supply, as much of Indonesia's electrical grid is based on alternating current (AC). To resolve this, a rectifier circuit is crucial to convert the AC input into a stable DC output using diodes, ensuring compatibility with the DC motor's requirements. The need for high-capacity and reliable DC power sources in industrial applications makes three-phase rectifiers necessary, as they can deliver higher power output compared to single-phase systems. This paper examines the operating principles, circuit topology, and diode configuration of the three-phase uncontrolled rectifier. By integrating these components, the rectifier enables efficient energy conversion and meets the operational demands of single-phase DC motors in industrial settings. Additionally, this study presents performance metrics such as power efficiency, voltage regulation, and thermal characteristics based on experimental results. The findings contribute to the optimization of rectifier systems in engineering, highlighting their importance in improving the reliability and scalability of DC motor systems for industrial automation and energy applications.
