CHAPTER 1 [pic] CHAPTER 1 INTRODUCTION 1.1 ORIGIN OF THE pop out This come out 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 experience There are numerous roofy whole kit out and boodle on diametrical voltage. Some work in 3 V, some are in 12 V. For this we convey many adapters or power bestow. So in this roam our pick out is to make a power supply or inconsistent adapter which can supply different 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 consequently 9 V output by changing our circuit which we will discuss later pa rt of this report. CHAPTER 2 PROJECT OVERVIEW 2.1 COMPONENT REQUIRED The component list for making the mold power supply or Variable adapter is as follows:- |No.
