Abstract –
There is a trend toward increasing the performanceof power electronics converters used in photovoltaic systems.However, parameters such as reliability, efficiency, andcomplexity might be in conflict. In this paper, the design of asimple DC/DC interleaved boost converter is assessed. It takesadvantage of state-of-the-art power devices that have fastswitching times. It is shown that requirements of low complexity,high reliability, and high efficiency can be satisfied, withoutresorting to switching aids, provided that the dev ....etc

abstract

neural-network-based implementation of
space-vector modulation (SVM) of a voltage-fed inverter has been
proposed in this paper that fully covers the undermodulation and
overmodulation regions linearly extending operation smoothly
up to square wave. A neural network has the advantage of very

Pulse Width Modulation is widely used in power electronics as a controller in power conversion and motion control. Among different types of modulating modes the Sinusoidal Pulse Width Modulation (SPWM) and Space Vector PWM are two common strategies in adjustable speed drive system. The Pulse width of SPWM varies with the Sine wave so as to restrain the lower order harmonics with easy control and large D C utilization. With successively improving reliability and performance of digital controllers, the digital control techniques have predominated ....etc

Abstract
This paper presents the development of asimple 1.5kW single-phase sinusoidal Pulse WidthModulation (PWM) inverter. This inverter isdesigned to be either a stand-alone or grid connectedinverter from a direct supply of photovoltaic (PV)cells. The developed inverter unit converts the DCinput supply from the PV cells into a clean sinusoidalvoltage output. This power inverter is also capable tobe a grid

Abstract
When no transformer is used in a grid-connected photovoltaic
(PV) system, a galvanic connection between the grid and
the PV array exists. In these conditions, dangerous leakage currents
(common-mode currents) can appear through the stray capacitance
between the PV array and the ground. In order to avoid
these leakage currents, different inverter topologies that generate
no varying common-mode voltages, such as the half-bridge and
the bipolar pulsewidth modulation (PWM) full-bridge topologies,
have been proposed. The ne ....etc

Introduction to Pulse Width Modulation (PWM)
In this technique several pulses are produced in each half – cycle but the width of the pulses
is not the same as in case of multiple – pulse width modulation, however the width of each pulse is
varied in accordance with the amplitude of the sine wave reference voltage. The width of the pulse
at the center of the half – cycle is maximum and decreases on either side. The figure 6(a) shows the
generation of the output signal by comparing a sinusoidal reference sign ....etc
