Abstract:-
Our varying industrial needs demand more precise control of the outputs of our basic electrical prime movers i.e, THE MOTORS. Basically dc motors are easy to control compared to their ac counter parts, but they have their own limitations with increase in capacity. Conversely ac motors in particular squirrel cage induction motors are very economical but their spee ....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

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

Abstract
A general pulsewidth modulation (PWM) method for control of four-switch three-phase inverters is presented. The proposed vector PWM offers a simple method to select three or four vectors that effectively synthesize the desired output voltage, even in presence of voltage oscillations across the two dc-link capacitors. The method utilizes the so called space vector modulation, and includes its scalar version. Different vector combinations are compared. The effect ofWye and delta motor winding connections over the pulse width modu ....etc

ABSTRACT
This paper focused on the development of capacitor voltage
balancing methods in a flying capacitor multilevel inverter
(FCMLI) fed induction motor drive. For improving the
performance of flying capacitor multilevel inverter, a switching
pattern selection scheme is implemented. The proposed method
has been designed a seven-level flying capacitor multilevel
inverter by using sinusoidal pulse width modulation technique.
The selected pattern has been exposed to give superior
performance in load voltage, total harmonics dist ....etc
