DC Power Supplies - Fundamental Concepts

Course No. E-2003

Credit: 2 PDH

Course Fee: $57.90 Purchase course

Subject Matter Expert: Edwin A. Carrell, P.E.

 

Overview

This course introduces the student to the purpose, function, and elements of the ubiquitous DC (direct current) power supply. Modern electronic devices generally require low-voltage DC sources to power their circuits. Some devices use battery or even solar power, but all others need a DC power supply, typically connected to a house or office AC (alternating current) wall outlet. These include radios, stereo systems, TV, computers, and other devices which we use daily.

The discussion starts with the primary power source - the wall socket, and a brief history about AC power. Several basic power supply configurations are described to support the functional concepts introduced. Features such as voltage transformation, i.e., changing the voltage from one level to another, and regulation, i.e., maintaining a constant output voltage, are presented and basic components are described. Important issues such as cooling requirements, protection circuits, and radio-frequency interference are addressed.

An understanding of the overall operation and performance characteristics of such power supplies will aid those in other disciplines who must accommodate power supplies in the definition, layout, or packaging of electronic devices.

The student must take a multiple-choice quiz consisting of ten (10) questions at the end of this course to obtain PDH credits.

 

Specific Knowledge or Skill Obtained

This course teaches the following specific knowledge and skills:

  • Process of transforming AC voltages to different levels.
  • Conversion from AC to DC.
  • Functional operation of a simple power supply.
  • Process and techniques for voltage regulation.
  • Hardware components involved.
  • Definitions of terminology and quantities.
