Development of Single-Phase AC Voltage Regulator for Renewable Energy Empowerment: Rural Generator Case Study

Abstract

This research focuses on the development of a single-phase AC voltage controller designed using SCR TIC126, diodes, IC regulators, Op-Amp LM324N, and other essential electronic components. The module is capable of producing variable AC voltage levels based on the triggering angle of the SCR, while maintaining a fixed output frequency. The output voltage waveform is analyzed through simulation using the PSIM software and verified mathematically. The key parameter measured is the Vrms output voltage. The observed differences between simulated, and mathematical values are minimal, ensuring reliability. The triggering angles used in this study are 45°, 60°, and 90°, with a resistive load of 5 W and 100 Ω. The source voltage applied is a low AC voltage of 12.8 V at a frequency of 50 Hz. This study is contextualized within a renewable energy program aimed at empowering rural communities. By utilizing this voltage controller, the research explores its potential in enhancing the performance of small-scale generators used in off-grid areas, particularly in enabling stable and efficient electricity supply for households and community facilities. The findings highlight the module’s applicability in community empowerment programs, offering a practical and scalable solution for improving energy access in underserved regions.
