Design and Implementation of a Three-Phase Half-Wave Uncontrolled Rectifier for Enhancing Rural Livelihoods through Single-Phase AC Motor Applications

Abstract

Electricity serves as a vital energy source for the survival and daily activities of the Indonesian people, supporting both their livelihoods and modern conveniences. In daily life, many tools and devices integral to productivity rely on single-phase electrical systems, including single-phase AC motors. While the development of Indonesia's electrical grid has advanced rapidly, introducing high-voltage three-phase power systems, a significant portion of equipment, particularly AC motors, still depends on single-phase power sources. This study focuses on the design and implementation of an uncontrolled half-wave rectifier to convert three-phase electrical power for single-phase AC motor applications. The aim is to explore practical and efficient energy conversion solutions that can support rural communities where single-phase power systems remain prevalent. The analysis was conducted using the Proteus 8 Professional application to simulate and test the rectifier’s performance under various conditions. To ensure a thorough understanding and reliable results, the research process included a preliminary online practicum using the PSIM application. By bridging three-phase power availability with single-phase motor requirements, this study contributes to addressing energy challenges in rural areas, supporting community empowerment, and enhancing productivity in underdeveloped regions.
