Arduino Based Motor Control Using LabVIEW
Abstract: AbstractSpeed of a DC motor varies proportional to the input voltage. With a fixed supply voltage, the speed of the motor can be changed by switching the supply on and off so frequently that the motor notices only the average voltage effect and not the switching operation. This project focuses on controlling the speed of a DC motor using PWM technique. The project basically consists of Arduino and motor driver, …

Harmonic Compensation in Grid Interconnected DG Units by Closed Loop Control
Abstract: This paper deals with improvement of power quality problem namely harmonic problem using distributed generation as their source of electricity. The harmonics occur in such a system because of the nature of loads connected. There are many power quality problems; out of which harmonics normally caused by nonlinear loads like variable frequency drives, fluorescent lightning, office computers etc. have adverse effects on the power quality. Also, harmonic detection and prediction …

Single-Phase Two-Stage Multi-Level Inverter Employing Low Number of Switching Devices
Abstract: In recent years, multilevel inverter (MLI) plays a significant role in low or medium voltage applications as a result of generating voltage with reduced harmonic contents. This paper proposes a new version of multi-level inverters (MLI) with reduced switching devices along with reduced harmonics content of output voltage, which results in low switching losses compared with conventional MLI topologies. In addition, the proposed inverter provides low total blocked voltage compared …

Cell Balancing in Lithium-ion Batteries – A Comparative Evaluation
Abstract: Balancing the cells within a battery system is essential for safeguarding against overvoltage, overcharge, and over-discharge, which can lead to system failures and safety hazards. Two commonly employed methods for cell balancing are passive and active balancing. In passive balancing, excess charge is dissipated through resistors, while active balancing involves the controlled flow of charge within the circuit. This paper focuses on the comparison and analysis of passive and two …
