3. Procedure
(1) Power Supply for an Audio Amplifier
A. PSPICE simulation
Conduct PSIPCE simulation for each step, and check the circuit system.
① Set the circuit as shown in fig 6-6, and get the half wave rectifying circuit signal.
② Set the circuit as shown in fig 6-7, and get the signal that has ripple.(To get ripple clearly, you can adjust capacitor)
③ Connect voltage regulator, then measure the wave. Is the ripple gone?
④ Set the circuit as shown in fig 6-11, measure the current flowing through transistor and the output signal of voltage regulator. Refer fig 6-4 for this PSPICE circuit diagram.

B. actual circuit design
① The Transformer
1) Apply commercial voltage(120Vrms 60Hz) to the primary side of transformer, inducing low voltage to the secondary side.
※ Caution : Never short secondary side.
2) questions
- Graph Vout using oscilloscope(Check Max, Min )
- Record Max/Min value of Vout.
