Lecture Notes - Chapter 11

Power Supply Circuits

(These Lecture Notes are for courses using the book the Complete Electronics Self-Teaching Guide with Projects. Instructors of courses using that text are permitted to use these Lecture Notes as-is or adapt them for their use).

  • Diodes in AC Circuits produce Pulsating DC
    • Review the ability of diodes to pass current in only one direction.
    • Discuss a simple circuit consisting of a diode and a resistor in series (figure 11.3).
    • Discuss the output signal for the circuit shown in figure 11.3 (figure 11.8).
    • Introduce the term: recitification.
    • Introduce the term: half-wave rectifier (figure 11.11
      • A half wave rectifier converts an AC input signal to a pulsed DC output signal.
    • Introduce the term: full-wave rectifier (figure 11.15)
    • Discuss the output of a full-wave rectifier (figure 11.16)
    • Introduce the term: out of phase (figure 10.4).
    • Introduce the term: bridge rectifier (figure 11.17)
    • Discuss the flow of current through the bridge rectifier (figure 11.18 and 11.19)
  • Project 11.1: The Full-Wave Rectifier
    • Discuss the objective of the project.
    • Review the circuit diagram (figure 11.21 and 11.22).
    • Review the test setup (figure 11.24).
  • Level DC (Smoothing Pulsating DC)
    • Discuss the sections of a power supply (figure 11.31).
    • Introduce the term: AC ripple.
      • The function of the smoothing section of a power supply is to take the pulsating DC and convert it to a pure DC with as little AC ripple as possible (figure 11.32)
    • Discuss the effect of capacitor C1 on the pulsating DC signal (figure 11-38 and 11-39).
    • Discuss the calculations to determine the value of R1.
    • Discuss the calculations to determine the value of C1.
    • Discuss the calculations to determine the value of C2.
    • Discuss the calculations to determine the amount of AC ripple.
