Unformatted text preview: and filter which provide an isolated, low- voltage, but unregulated DC voltage as shown in Figure 1. This is basically what you studied in Lab 2. Fig. 1. The basic unregulated AC to DC power supply We can improve this supply by using electronics to regulate the output from the rectifier/filter, and produce a stable (but adjustable) voltage that is essentially independent of load. Since the voltage does not vary with load, it appears to have zero internal resistance. Naturally, our voltage source cannot provide infinite current; but within its ratings it can be considered very nearly an "ideal" voltage source. There are a number of ways to describe how a regulated supply operates. For example, it can be considered a “voltage follower” or simply an operational...
