Design of a Three-Phase Full-Wave Uncontrolled Rectifier for Sustainable Energy Solutions in Rural Communities

Abstract

This study focuses on designing and implementing a three-phase full-wave uncontrolled rectifier system to convert alternating current (AC) from local energy sources, like small-scale generators, into direct current (DC) for rural communities. A rectifier circuit, primarily consisting of diodes, plays a vital role in energy conversion. In controlled rectifiers, an AC voltage is modified into stable DC voltage for a reliable power supply. The three-phase rectifier offers high output power by utilizing both positive and negative cycles of the AC signal, ensuring continuous, stable energy. In an uncontrolled rectifier, a capacitor is used to reduce ripples in the output, making the current closer to ideal DC, crucial for many energy system applications. This conversion process is essential for providing consistent electricity in remote areas for domestic and community activities. The methodology of this research includes identifying energy needs in rural areas, followed by calculations and system flowcharts to create an efficient rectifier system. A detailed simulation predicts the system's real-world performance. Data collection and measurements validate the system's functionality and efficiency. By conducting these stages, the study demonstrates how a three-phase uncontrolled rectifier integrated with a three-phase AC generator can provide sustainable and reliable energy solutions for underdeveloped rural communities. This approach can improve livelihoods and economic stability through consistent access to electricity. Ultimately, the research aims to highlight the social impact of such technology, enhancing the quality of life for underserved populations in rural areas.
