Project Report on Semiconducting..

CHAPTER 1 [pic] CHAPTER 1 INTRODUCTION 1.1 ORIGIN OF THE swan This purge has been prepared as an outcome of our ECR-205 anatomy that we are having for our B.Sc in technology 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 catch There are numerous lap covering whole equip and boodle on unalike voltage. Some work in 3 V, some are in 12 V. For this we requirement many adapters or power return. So in this devise our pick out is to make a power supply or inconsistent adapter which can supply varied 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 accordingly 9 V output by changing our circuit which we will discuss later part of this report. CHAPTER 2 PROJECT OVERVIEW 2.1 COMPONENT REQUIRED The component list for making the play power supply or Variable adapter is as follows:- |No. |Name |Model Number |Parameter | emblem | cadence | |1 |IC |LM317T |- |Ic1 |1 | |2 | rectifying tube |1N4001 |- | D |4 | |3 | condenser |- |2200 mfd/25v |C3 |1 | |4 |Capacitor |- |0.22 mfd/160V ! |C4 |1 | |5 |Capacitor |- |10 mfd/40v |C5,C6 |2 | |6 |Transformer | |12V, 1A |-...If you want to get a full essay, lay out it on our website: OrderCustomPaper.com
