Design and Simulation of Asynchronous Buck Converter using Fuzzy Logic Controller (FLC)

Abstract

Currently, Indonesia's energy is running out and
has received serious attention so the Government targets that
by 2050 the role of renewable energy will be at least 31%. This
encourages the production of various alternative energy
sources that are environmentally friendly and available, such
as solar power plants. However, solar intensity and a dynamic
environment strongly influence the output power generated by
solar panels. So in this research, an asynchronous buck
converter design using MPPT will be made to track the
maximum power point of solar panels with the fuzzy logic
controller method which will be applied to Monocrystalline
solar panels with a capacity of 300WP. Fuzzy MPPT will adjust
the duty cycle by PWM Arduino Nano on the asynchronous
buck converter to keep reaching the maximum power point.
The results show that the developed system can increase power
conversion efficiency and maintain output voltage stability
under various operational conditions. The implementation of
FLC as MPPT on Asynchronous Buck Converter successfully
optimizes the power absorbed from solar panels, thus
supporting the reduction of electrical energy consumption from
PLN in the Jakarta Global University student association
secretariat building. This implementation is expected to be a
reference for the implementation of a smarter and more
sustainable energy management system in the future.
