Unformatted text preview: UND Passive voltage sources such as batteries are non- ideal because they contain series resistance (Remember the Thevenin resistance of the battery in Lab 3 in ENGR 210), as well as an output voltage that exhibits variability and noise. Even with great effort, it is impossible to construct a passive voltage source that can be considered "ideal". We can, however, employ electronic circuitry to enhance a "real" voltage source so that it exhibits characteristics that closely approach that of an ideal one. This can be accomplished using either linear or switching approaches. Our power supply is a linear voltage source, but the concepts discussed herein generally apply to both techniques. Most linear power supplies start with a transformer, rectifier,...
