Chapter 7

Power Supplies

Abstract

The power supply is a vital but often neglected part of any electronic product. It is the interface between the noisy, variable, and ill-defined power source from the outside world and the hopefully clear-cut requirements of the internal circuitry. For the purposes of this discussion, it is assumed that power is taken from the conventional ac mains supply. Other supply options are possible, for instance a low-voltage dc bus or a standard aircraft supply of 400 Hz 115 V. Batteries will be discussed separately at the end of this chapter.
