Prototype Control of DC-DC Boost Converter in Solar Cell Energy Management System Based on Fuzzy Logic Method

Abstract

Population growth greatly affects the world's electricity consumption, so there will come a time when renewable energy is needed to be an alternative to the generation system from fossil fuels. The generation of energy derived from renewable energy requires a range of converters and storage systems. The research methodology used is to use the DC-DC boost converter topology to regulate the output voltage of the dc bus connected to a 12W DC lamp load when the photovoltaic source is unable to meet the load power demand. This research focuses on the goal of designing a DC-DC boost converter on a photovoltaic system, being able to use battery power with a DC-DC boost converter to maintain load power supply, and adjusting the PWM boost trigger using the fuzzy logic method. The DC-DC boost converter is designed with component calculations using the boost converter equation which worked well in boost mode testing with an average percent error value of 3.88%. The DC-DC boost converter system with the fuzzy logic method successfully uses batteries to maintain the load power during data retrieval, the load voltage is maintained between 13.89V to 14.06V with a power range of 9.91W to 13.73W. The fuzzy logic method implemented successfully regulates the work of declaring MOSFET boost so as to produce a voltage close to the reference voltage of 14V with a voltage range of 13.89V to 14.06V using an accumulation of PWM values with a range of values of 53.07 to 56.89.
