MODIFICATION OF ALTERNATING CURRENT GENERATOR SYSTEM SIMULATOR: ANALYSIS USING BRUSHLESS DIRECT CURRENT MODULE

Abstract

This study aims to design and test a simulator of the alternating current
generator starter system using a step-up dc to dc converter and a brushless
direct current controller as an instructional medium. The simulator is
developed to help learners understand the working principle of the
alternating current generator starter system, which integrates the functions
of both a starter and an alternator into a single unit. The research method
employed is a technical and experimental approach, which includes needs
analysis, component selection, assembly, and both electrical and
mechanical testing. Testing was carried out to ensure the functionality of
each part, such as increasing the voltage from 12V to 36V and regulating
current through the brushless direct current controller to rotate the rotor.
The results indicate that the simulator accurately replicates the operational
characteristics of the alternating current generator starter system,
including the relationships between voltage, current, rotor speed, and back
electromotive force. Electrical stability and the simulator frame ensure the
simulation runs smoothly without mechanical disruption, making it
appropriate for educational and technical training purposes and offering
potential for further development.
