Unformatted text preview: ECE 2B Lab 2: Linear Power Supply Joseph Marcus ECE 2B Lab 2 Tuesday 5:00-7:50 July 13, 2009 Experiment Title : Linear Power Supply Introduction and Objective : The objective of this lab is to build a regulated dc power supply to provide a low- ripple adjustable dual-output voltage in the range of +/- 9 to 12VDC at 0.2 Amps (maximum) load current from a 120 VAC power outlet. This power supply will be used to provide power to circuits built during other courses. In this lab, a basic understanding of the operation and design of linear supplies and techniques for construction of hardwired electronic circuit modules is intended for those building the circuits. This lab will provide the students with experience using power transformers, diode bridge rectifiers, capacitive loading for ripple rejection, use of electrolytic capacitors, power resistors, use of IC voltage regulators, using LED indicators, and basic soldering techniques. Experimental Procedure and Data : 2.1 AC Power Transformer A given power transformer that is prewired to a 120V AC power cord with an inline fuse, is specified for 115 VAC input (primary) and an 18 VAC center-tapped output...
