THE DESIGN AND CONSTRUCTION OF A 220 / 12 VOLTS SINGLE PHASE STEP-DOWN TRANSFORMER

ABSTRACT  This is a technical project write-up design and construction were carried out by me with deep intensive and extensive research work.  I all give credit to the authors of the textbooks whose I referred to in the cause of writing this project and its subsequent design and construction. In this project, I shed light on the basic principle of operation, the design and construction procedure.  Critical analysis of all the functional parts of the transformer and rectifier connected to it. It will therefore, be of great in serest and suitable to all electrical engineers and engineering students.     TABLE OF CONTENT Cover Page Approval Page Dedication  Acknowledgement  Abstract  Table of Content
