Trace the flow of AC and DC in a power supply from the AC input to the DC
output on a schematic diagram.
Identify faulty components through visual checks.
Identify problems within specific areas of a power supply by using a logical
isolation method of troubleshooting.
Apply safety precautions when working with electronic power supplies.
INTRODUCTION TO POWER SUPPLIES
In today's Army, all electronic equipment requires a power supply. Because of new
technology and equipment, the solid state power supply must also be explained. The
discovery of the silicon diode and other solid state components made possible the reduction
in size and the increase in reliability of electronic equipment. This is especially important
in mobile equipment where space and accessibility to spare parts are a major concern. In
this chapter, you will learn about the individual sections of the power supply, their
components, and the purpose of each within the power supply.
