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

The vibration load subjected to many products is the combination of several random processes corresponding to different application conditions, such as the various field road load inputs for automotive components. Sometimes the input loads are the combination of random and sinusoidal vibration. Due to the convenience of test setup and monitoring, the sinusoidal vibration sweep tests are often used for product durability validation by many automotive and consumer product manufacturers. It is therefore important to correctly correlate the sweep ....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

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

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
