CHAPTER ONE INTRODUCTION 1.1       Preamble A power inverter, or inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC). ( The Authoritative, 2000 ). The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The... Continue Reading

ABSTRACT In this project work, we are mostly concern about building a simple power streetlight which is automatically operated. There are four main components required to build a solar operated streetlight. The solar array, High efficiency D.C lamp section made by transistor, resistors, and the sensor LDR, changes controller which is made up of... Continue Reading

ABSTRACT Automatic gate is one of most usefully thing to use in companies, colonies, collages, homes, and schools. There is some type to operate a gate such as a sliding on screw or on rack and pinion, piston operated, rotary. Design is available for some type of operation and it is most costly also When installation and maintenance cost is not... Continue Reading

Abstract A solar ovenis a device that converts solar energy into useful heat in a confined space (oven chamber) which can be utilised for cooking and baking purposes.The oven consists of plane reflectors to concentrate the solar radiation on the collector.The heat gain is maximum if the collector and reflectors are continuously adjusted such...
