# 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.
