CHAPTER 1
INTRODUCTION

Every day of your computing life, you reach out for the mouse whenever you want to move the cursor or activate something. The mouse senses your motion and your clicks and sends them to the computer so it can respond appropriately. An ordinary mouse detects motion in the X and Y plane and acts as a two dimensional controller. It is not well suited for people to use in a 3D graphics environment. Space Mouse is a professional 3D controller specifically designed for manipulating objects in a 3D environment. It permits the ....etc

Pulse Based Dead Time Compensator for PWM Voltage Inverters



I. Introduction
The state of the art in motor control provides an adjustable
voltage and frequency to the terminals of the motor
through a pulse width modulated (PWM) voltage source inverter
drive. As the power devices change switching states,
a dead time exists. Although the dead time is short, it
causes deviations from the desired fundamental output voltage.
While each deviation does not appreciably affect the
fundamental voltage, the ac ....etc
