Abstract— This paper presents unipolar pulse width modulation technique with sinusoidal sampling and Space vector pulse width modulation are analyzed for three-phase Diode clamped multi-level inverter from the point of view of the Phase voltages, currents, voltage across the split capacitors and Total harmonic distortion. The necessary calculations for generation of PWM for the two modulation strategies have presented in detail. It is observed that the unipolar modulation ensures excellent, close

Introduction: Due to increased concern on energy crisis and environmental issues, power industry is shifting their power production from conventional power sources to renewable energy sources, and is incorporating it into the grid utility in the form of distributed generations (DGs). The application of DGs can enhance reliability and stability of the local network, and can reach benefit to the supplier by reducing system losses and investment on a new transmission line due to increased power consumption

1.0 INTRODUCTION The purpose of this project is to design a functional prototype of monitoring system for a security purpose and the system use WIFI as a transmission medium. Standard monitoring systems such as CCTV use cable to connect from a camera to the monitoring station. This project is intended to use a wireless transmission to transmit video from camera to monitoring station. This project also to overcome the power supply issues of main power supply to operate the device. The uninterruptible

Artificial light since its creation has benefited society by creating more time for a productive day not only for work but also recreational activities. Artificial light has many benefits, however when the excessive light does create negative impacts such as becoming inefficient, annoying, and unnecessary. Many officials such as environmentalists, medical researchers, and naturalists agree that light pollution is one of the most rapidly growing and widespread forms of environmental pollution. More

The Effect of Distributed Generation on Power Quality of Iraqi power System Networks. Abstract: The primary motivation behind this paper is to examine the essential comprehension of power quality in connection to the distributed generation. Because of extensive cover between two innovations, aggravations influencing the power quality, which are principally caused by the expansion of Distributed Generation (DG) on the existing power system network. Infusion of the DG into an electric power grid

implemented in Implicit Zero Sequence Discontinuous Pulse Width Modulation (IZDPWM) technique that is compatible for grid connected inverters. Regarding in the IZDPWM grid topologies distorted the harmonics of the grid voltages. Hence, a sinusoidal current is injected to the grid. Moreover, the measuring grid line-to-line voltages two sensors are required; hence an overall system costs is reduced and control system reliability is increased. The time-domain simulations in MATLAB/Simulink and experimental
