Abstract

This research designs and makes an analysis of the performance of a solar panel-based DC-DC boost converter topology using an Arduino Uno microcontroller. Boost converter is given a variation of inductor wire with 30 turns and 60 turns using a diameter of 1 . This research was conducted to obtain the highest characteristics and efficiency of the performance of the boost converter that has been designed and made for each inductor wire turn variation. In this research, data analysis will be carried out, namely the effect of duty cycle on voltage and current, and how the effect of variations in the number of inductors turns on the efficiency of the boost converter. This circuit uses an arduino uno microcontroller to generate and control the duty cycle on pulse width modulation (PWM) to regulate and increase the desired output voltage. The inductor on the DC-DC boost converter with a wire variation of 60 turns at a diameter of 1  gets the highest efficiency with an average efficiency of 67.13 , while the inductor wire with 30 turns gets an average efficiency of 66.32 .  The maximum voltage generated by the solar panel used as the main source of electrical energy in the boost converter is 20.0  and the control system that has been applied to the arduino uno microcontroller can control and generate a duty cycle with a ratio of 0  - 90 .  The boost converter circuit made gets low efficiency due to the presence of MOSFET components that work in non-ideal conditions, which causes excessive power losses.

Abstract

Inductors have a significant influence on the volume, weight, cost, and performance efficiency of converters. In boost converters, the size of the inductor greatly affects the overall size of the converter. In recent years, there has been an increasing number of researches focusing on modeling power losses in magnetic elements and on the influence of power losses in these elements on the characteristics of electronic equipment. Boost converters often operate under non-ideal conditions, when the switch is active for a long period of time (Switch ON), conduction losses increase, high current ripple occurs, and the switch operating cycle is extreme. The magnitude of current ripple in a boost converter will greatly affect the amount of power loss generated in the inductor or MOSFET. Given this, it is important to consider the inductor's ability to overcome power losses that will affect the performance of the boost converter. This research analyzes the effect of inductor size, voltage, current, and efficiency related to the duty cycle. The purpose of this research is to find the highest efficiency by varying the diameter of the inductor wire. The diameter of the inductor wire will affect internal resistance and power dissipation, which will have an impact on the performance of the boost converter. Based on the research results obtained, a diameter of 1.5  achieved the most optimal performance with an efficiency of 69.05. Increasing the diameter of the inductor will improve its ability to store current  and reduce internal resistance, thereby overcoming the magnitude of current ripple , reducing power losses due to heat, and converting energy efficiently.
