SUMMARY
4-146. Now that we have completed this chapter, the following is a short review of the
more important points. Answer the check-on-learning questions, found after the summary,
to determine how much you have learned from this chapter.
POWER SUPPLIES - electronic circuits designed to convert AC to DC at any
desired level. Almost all power supplies are composed of four sections:
transformer, rectifier, filter, and regulator.
POWER TRANSFORMER - the input transformer for the power supply.
RECTIFIER - the section of the power supply that contains the secondary
windings of the power transformer and the rectifier circuit. The rectifier uses
the ability of a diode to conduct during one half cycle of AC to convert AC to
DC.
HALF-WAVE RECTIFIERS - gives an output on only one half cycle of the input
AC. For this reason, the pulses of DC are separated by a period of one half
cycle of zero potential voltage.
