Regulated Power Supplies – Transmitters, Modulation, and Processing

This chapter dives into the intricacies of regulated power supplies, a cornerstone in the realms of transmitters, modulation, and signal processing. It begins by examining the series-regulated power supply, focusing on the relationship between power dissipation in the pass transistor and the load current and voltage differential. This sets the stage for a broader exploration of the characteristics and performance of regulated power supplies, including the distinction between static and dynamic regulation and the pivotal role of components like fuses and capacitors. The discussion also covers the connection of electrolytic filter capacitors to voltage regulators and the vital function of diodes in protecting against reverse voltages. Understanding these elements is crucial for anyone involved in designing or operating electronic equipment, particularly in areas requiring precise voltage control such as communication systems and complex signal processing.
