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
A new zero-voltage-switching (ZVS) control approachis presented for pulsewidth modulation (PWM) buck convertersunder discontinuous conduction mode (DCM)/continuousconduction mode (CCM) boundary. This proposed technique compensatesfor control circuit delay, and hence, turns on power MOSat the instant exactly when drain-to-source voltage becomes zero.No complicated timing calculation circuits or additional externalcomponents are required. This proposed integrated ZVS controlcan be applied to other dc–dc converters as well. The ....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

Current-Fed Resonant Full-Bridge Boost DC/AC/DC Converter
INDIRECT dc/ac/dc converters utilizing an isolation transformer
are widely used in different applications, such as
battery chargers and dischargers, uninterruptible power systems,
alternative energy systems, hybrid electric vehicles, and
medical X-ray imaging.
In the case of the applications where low input voltages have
to be converted to high output voltages, current-fed converters
are used, whereas in the case of higher power applications, fullbridge
boost conv ....etc

Implementation of Full-Bridge Current-Fed Resonant Boost Converter using PIC microcontroller
ABSTRACT
This paper presents a current-fed full-bridge boost DC-ACDCconverter with transformer isolation operating withoutswitching power dissipation. The output voltage is regulatedby dc-ac converter whose frequency changes with a constantturn-off time of transistors. The proposed converter is devoidof parasitic oscillations, as all of the parasitic capacitancesand inductances are included in a resonant tank circuit. Themain advantage of such ....etc

AIM:

Aim Of the Project Is Get the Energy From non conventional Energy Source To Convert 400v 3phase Energy. Using 3phase Zv ZC Switching Dc-Dc Convert For Fuel Cell Application.

ABSTRACT:
In spite of having many advantages, such as low
switch voltage and easy implementation, the voltage-fed dc–dc
converter has been suffering from problems associated with large transformer leakage inductance due to high transformer turn ratio when it is applied to low-voltage, ....etc
