Introduction

An inverter is an electrical device that converts direct current (DC) to alternating current (AC); the converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits.
Static inverters have no moving parts and are used in a wide range of applications, from small switching power supplies in computers, to large electric utility high-voltage direct current applications that transport bulk power. Inverters are co ....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

Introduction
The zero-cross family of optically isolated triac drivers is an inexpensive, simple and effective solution for interface applications between low current dc control circuits such as logic gates and microprocessors and ac power loads (120, 240 or 380 volt, single or 3-phase). These devices provide sufficient gate trigger current for high current, high voltage thyristors, while providing a guaranteed 7.5 kV dielectric withstand voltage between the line and the control circultry. An integrated, ze ....etc

this project is intended to make a circuit for detect when the motor shaft comes to a halt,here a small contactor attached to the shaft of the motor. As the motor rotates this contactor touches two pins A and B there by giving pulse to the comparator through a trigger circuit. As soon as the connection is established the output of the comparator changes and remains at that state for some time say for 0.25 seconds, before the output can change back, the contactor touches the pins again and again triggers the comparator. This continues as long a ....etc
