Designing and Manufacturing a Single-Phase Transformer and Analyzing Its Performance

Aims: This work aims to design a single-phase transformer for analyzing its performance based on some requirements. Study Design:  At first, requirements are set, then the design was completed using AutoCAD, after that the designed machine was simulated in MATLAB Simulink, manufactured in real-time in the laboratory, tested experimentally, and then the equivalent circuit parameters were computed from the experimental data. Place and Duration of Study: The design, manufacturing, simulation, and performance testing were conducted in the electrical machine 1 laboratory of American International University-Bangladesh (AIUB). It took around four months to complete the whole task. Methodology: This work is a bit expensive and complicated process for students without any funds. So, a group was formed with eight students. The tasks were to design, simulate, implement, and test a single-phase transformer that would step down 220 V (ac) to 110 V (ac) having a 440 VA capacity, and core loss should not exceed 5 W. Results: MATLAB Simulink was used to simulate the designed transformer to get the primary and secondary winding voltage and current wave shapes that were confirmed by the experimental results. Open and short circuit tests indicate that loss is only between 5 W and 8 W respectively. The total design cost is only BDTK1, 270. Conclusion: The results satisfied the design and performance parameter requirements and the designed transformer worked very well. The design cost was also kept minimum.
