CHAPTER 1 [pic] CHAPTER 1 INTRODUCTION 1.1 ORIGIN OF THE find out This communicate has been prepared as an outcome of our ECR-205 anatomy that we are having for our B.Sc in engineer 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 range There are numerous electric circuit whole fit and boodle on contrary voltage. Some work in 3 V, some are in 12 V. For this we essential many adapters or power put up. So in this forecast our pick out is to make a power supply or inconsistent adapter which can supply distinct 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 past 9 V output by changing our circuit which we will discuss later p art of this report. CHAPTER 2 PROJECT OVERVIEW 2.1 COMPONENT REQUIRED The component list for making the intone power supply or Variable adapter is as follows:- |No.
