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

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

A Neural-Network-Based Space-Vector
PWM Controller for Voltage-Fed
Inverter Induction Motor Drive




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
fast implementation of an SVM algorithm that can increase the
converter switching frequency, pa ....etc

I'm using an AVR Mega 168 to generate a sine wave via pulse width modulation. My goal is to generate a sine wave with a frequency of approximately 50Hz. I understand that the PWM frequency needs to be as fast possible so its easier to attenuate in the filter. ....etc

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
