  2. PSpice Analysis of AC Circuits • We must use AC sources, and tell PSpice to perform an AC analysis at specific frequency(ies) • PROBE allows us to plot our results • Take advantage of features (e.g., cursors) to assist your analysis • Completely annotate your schematic diagrams • MOST IMPORTANT RULE: You will always get an answer, you must judge its validity! ECE201 Lect-26

  3. AC Sources in PSpice • VAC is used to represent an AC voltage source in PSpice; IAC is for an AC current source • Both the magnitude (ACMAG) and phase (ACPHASE) value can be set for the source • The frequency is not set using the source • VSIN and ISIN are transient sine sources ECE201 Lect-26

  4. PSpice AC Frequency Selection • The frequency selection is specified in the AC Sweep option of the Analysis Setup • PSpice can be used to analyze a circuit at a single frequency (for example, 60 Hz) or for an entire range of frequencies (variable) • Single frequency: select a linear sweep with 1 point using same start and end freq. • VPRINT may be used to output results ECE201 Lect-26

  5. PSpice Variable AC Frequency • Variable frequencies: typically select a decade sweep with about 20 pts/decade with a start and end frequency, respectively, well below and well above the frequencies of interest [think of it as taking a photograph] • These results are graphed using PROBE; and this is made easier using voltage and current markers ECE201 Lect-26
