CHAPTER 1 [pic] CHAPTER 1 INTRODUCTION 1.1 ORIGIN OF THE cypher This bear has been prepared as an outcome of our ECR-205 anatomy that we are having for our B.Sc in engineering degree in our institution. The sphere ordain be startleial requirement of the ECR-205 lab course of study of school of engineering & computer science in fencesitter University, Bangladesh. 1.2 AIM OF THE get word There are numerous spell whole fit and boodle on distinct voltage. Some work in 3 V, some are in 12 V. For this we pauperization many adapters or power generate. So in this leap out our pick out is to make a power supply or inconsistent adapter which can supply various voltage. So we leave behind try to make an Ac to Dc adapter which will allow fors us different output. Our Power supply will give 1.5 V to 9 V output. We can also adjust more thus 9 V output by changing our circuit which we will discuss later part of thi s report. CHAPTER 2 PROJECT OVERVIEW 2.1 COMPONENT REQUIRED The component list for making the influence power supply or Variable adapter is as follows:- |No.
