The electricity is provided by a welding power supply, and can either be AC or DC. For Variable Power Supply (30V, 2A) (100 sets) 1. Sanction of loan by 3 . Some types of welding can use as few as 10 amps, while some applications of spot welding employ currents as high as 60,000 amps for an extremely short time. The reference voltage maintained stable even for the fluctuations and the noise components occurred in the voltage. For this purpose we have to assemble a rectifier circuit on the output of a transformer. Preparation of project report 1 2. INTRODUCTION: It is a simple variable dc power supply which gives 5 to 12 dc volts as an output.here we use a simple full wave rectifier along with a voltage regulator which give a constant output and its output can be increased by using a pair of voltage divider resistor in which one resistance is variable to get . 2. BACKGROUND: Our respectable teacher Eng obaid sabir give us a project to make a variable dc power supply We got the idea of this project while reading the full wave rectifier and almost every group use the full wave rectifier with little bit changing in their circuit. POWER SUPPLY SYSTEM The power supply system has an input which is either ac or dc and, for our discussions, a dc output. Summary. using 4 diodes which rectifies the output of the step-down transformer which step-. The input could be the 240V 50Hz mains supply or a dc supply from a car battery or even a power rail within an existing circuit. BACKGROUND . THE PENNSYLVANIA STATE UNIVERSITY EE 310: ELECTRONIC CIRCUIT DESIGN I Power Supply Design Project William Stranburg Introduction: Scope The purpose of this laboratory was to design a power supply capable of taking a AC voltage and convert it into a low regulated DC voltage. The DC power supply has wide applications in the modern world. - A smoothing circuit using inductors and . DC Power Supplies ((9V/12V-500mA) are modular power supplies used as power .
