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

An electric motor is an electromagnetic machine commonly utilized across various industries and automotive products. One prevalent type of electric motor employed in electric vehicles is the Permanent Magnet Brushless DC Motor (PM-BLDC), a brushless motor employing permanent magnets. However, despite its efficiency, permanent magnet motors often experience vibrations that can disrupt their performance. This research aims to optimize the existing BLDC motor design, with a specific focus on reducing the existing cogging torque. Initially, the existing design exhibited a cogging torque level of 0.21482 Nm. The optimization process involved modifications to several key design parameters, such as air gap, magnet thickness, magnet type, and slot opening width. In previous research, only comparisons were made between stator slot designs, which proved to be less effective as significant differences were not evident in the results of the comparative analysis of BLDC motor designs. So, in this research, the Taguchi method was utilized for the optimization process due to several advantages it offers. Through an analysis of means and variance, the optimization process successfully achieved a significant reduction in cogging torque by 0.099744 and an increase in efficiency by 0.6%. The results of the optimized permanent magnet BLDC design indicated a cogging torque value of 0.115072 Nm and an efficiency of 86.64% at an operational motor speed of 1500 rpm. This research provides a substantial contribution to the development of more efficient electric motors suitable for various applications.
