CTE Resource Center - Verso

Virginia’s CTE Resource Center

Describe the characteristics, operation, and applications of power-supply circuits.


Description should include the
  • characteristics of power-supply circuits—basic stages and associated components
  • basic purpose or function of a power-supply circuit
  • operation of power-supply circuits—graphing the voltage pattern at each stage of a power supply’s operation
  • types of voltage regulators and how they operate
  • applications of power-supply circuits (e.g., DC power supplies, AC power supplies, switching power supplies associated with computers and digital electronics).

Process/Skill Questions

  • Which components are used as power supplies?
  • What are the characteristics of power supplies?
  • How are power supplies classified?
  • What are the different types of rectifiers?
  • What are the comparative features of fuses, slow-blow fuses, and circuit breakers?
  • How does a rectifier circuit work?
  • What is the difference between a transformer and an inductor?
  • What is the difference between a voltage regulator and a shunt regulator?
  • What are the strengths and weaknesses of a series regulator?
  • What are common examples of products containing over-voltage protection circuits?
  • What are the implications of ripple frequency?
