Electrical Engineering Circuit Analysis Lab: PSPICE AC Analysis Report

This lab report, conducted at the University of Sharjah's Electrical and Electronics Engineering Department, focuses on the application of PSPICE software for AC circuit analysis. The experiment, titled "Introduction to PSPICE – Part III (AC Analysis)", aims to familiarize students with phasor analysis in both time and frequency domains, and to determine the frequency response of AC circuits. The report includes solutions to homework problems, demonstrating the use of PSPICE to calculate voltages and currents in various circuit configurations, including the determination of magnitude and phase. The report also includes Bode plots and linear plots to visualize frequency response. The conclusion highlights the use of PSPICE for phasor analysis, explaining the measurement of voltage, current, and voltage differences using IPRINT1, VPRINT1, and VPRINT2, along with the utilization of VAC and IAC sources. The experiment provides practical examples of how to use PSPICE to analyze AC circuits.

Introduction to PSPICE – Part III (AC Analysis)
OBJECTIVES:
1. To learn the use of PSPICE for Phasor analysis of circuits in both time and frequency
domains.
2. To learn the use of PSPICE to obtain the frequency response of AC circuits.
Homework:
Practice Problem 1: Using w = 1, obtain Vx and Ix in the circuit depicted in Fig- 1.10
Figure 1.10 For Practice Prob. 1.1.
Answer: From the output file Vx = 9.84/44.78o Ix =2.584/158o A

Vx = 9.84/44.78o Ix =2.584/158o A
Ix(t) = 2.584 Cos(t+158) Amps
Practice Problem 2: Find ix(t) in the circuit in Fig. 1.11.
Figure 1.11 For Practice Problem. 1.2
Answer:

From the output file. ix = 7.59/108.43o, Therefore, ix(t) = 7.59cos(4t+108.43o).
Practice Problem 3: For the circuit in Fig. 1.7 replace the capacitor C with an inductor L = 4 mH and
obtain the magnitude plot (both Linear and Bode) for vo for 10 < f < 100 MHz.
Answer: See the plots in Fig. 1.12

Conclusion:
In this experiment , we learned a NEW Pspice III use which is Phasor Analysis , in the the
phasor analysis , we can measure voltage , current and voltage difference between 2 point
by (IPRINT1) , (VPRINT1) AND (VPRINT2) , we also added newly voltage and current
sources different than the old voltages and current sources of Pspice I which are (VAC) and
(IAC) , frequency can be calculated by F=w/2*pi*
