Chapter 4
Solid State Power Supplies
LEARNING OBJECTIVES
Learning objectives serve as a preview of the information you are expected to learn in this chapter.
The comprehensive check-on-learning questions, found at the end of the chapter, are based on the
objectives. Upon completion of this chapter, you will be able to perform the following learning
objectives:
Identify the various sections of a power supply.
State the purpose of each section of a power supply.
Describe the operation of the power supply from both a whole unit standpoint
and from a subunit standpoint.
Describe the purpose of the various types of rectifier circuits used in power
supplies.
Describe the purpose of the various types of filter circuits used in power
supplies.
Describe the operation of the various voltage and current regulators in a
power supply.
Describe the operation of the various types of voltage multipliers.
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
4-1.
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.
