Applying the advantages of the GUI, new menu driven intelligent tutoring system was developed. The software allows the user to draw the single line diagram representing the power system with ratings of each component. The software calculates the corresponding per-unit values and the change of impedance of individual component referred to the common system MVA. These per-unit values can be used to draw the reactance diagram of symmetrical components automatically. Therefore, it becomes a convenient approach for creating an interactive tool in teaching and learning the power system. The aim of this project is to make teaching and learning more productive and efficient by employing modern technologies. It is hoped that this software will enhance the learning process and make it more interactive, interesting and user friendly.

This paper discussed a brief review of THD in different cascaded H-bridge multilevel inverter topologies of five levels and seven levels at the output waveforms. The five levels inverter contains eight switches while seven levels inverter used twelve switches. Each single H-bridge inverter circuit is fed by equally independent DC source for both inverters. The inverter uses MOSFET as the switching point and acts as the controller for a fundamental switching operation. The switching value has been set at the gating block to control the operation of the MOSFET switching. Several waveforms and simulation findings are provided to validate the quality of the proposed topology.

Mostly a multilevel inverter is used to generate the AC voltage from DC voltage. The aim of this paper is to investigate the output of 9 level multilevel inverter by modifying the conventional 5 levels H-bridge cascade multilevel inverter.

One of the critical elements in LEDs lamp in ensuring optimal performance and long operating life is the LEDs driver. The driver performs a number of functions such as power conversion, power factor correction (PFC), voltage isolation and current regulation. The main focus of this project is to improve the LED driver characteristics using Cuk topology for greater durability and efficiency. The Cuk converter is considered the optimum topology with non pulsating input current, non pulsating output current, minimum storage elements, minimum switch number, and high energy storage density using a capacitor instead of an inductor, which can operate as step up or down converter. The PIC microcontroller is used as a main controller for providing constant current to the LED. This project is designed and simulated and a prototype is developed. It has been found that the performance of developed prototype is excellent with the efficiency greater than 90% at minimum and maximum input voltage. The simulation and experimental results proved that the Cuk converter is appropriate to be used as LED driver for LED replacement lamp.

Due to its nonlinearity, the model parameters cannot be obtained by the use of standard measurement tools. As a consequence, the optimization procedure usually carried out to accomplish this aim. Among many PV cell models, the single diode model (SDM), consisting of a single diode with shunt and series resistance, has become a common simulation option. There are five parameters to be extracted in this model. These are photo-generated current, diode saturation current, series resistance, shunt resistance and diode ideality factor. In this paper, the Animal Migration Optimization (AMO) algorithm has been proposed to extract these parameters. Standard measurement data from the R.T.C France silicon cell is taken as a test bench. The results of AMO contrast with the state-of-the-art algorithm for further verification. As a conclusion, the AMO produced quick, reliable and accurate results. However...
