Phase angle plot and Mark the values at the frequency corresponding to the peak Use Label from the Tools menu and Mark the values at the Select Cursor from the Tools menu, select the Display and use Peak toįind the peak voltage. From Plot use Add Y axis to create a new Y-axis, and add the In probe, Add Plot from the Plot menu to create two graphs on Times such that their corresponding nodes are entered as 2 0, and 3 0 respectively. Since the dotted terminal is always the first pin in the Netlist, L1 and L2 are rotated three Also, find the frequency at which the impedanceįirst we calculate the coefficient of coupling Determine the frequency at which theĪmplitude of the output voltage V o is a maximum find the Use the AC analysis to sweep the sourceįrequency linearly from 20 HZ to 280HZ in steps of 1HZ. The magnitude and phase angle of the output voltage V o, i.e., V(4) as a function of frequency. The output file contains the following values for the magnitudeįrom the above results, the mesh currents are:įor the circuit shown, use PSpice and Probe to graph Enable the AC Analysis, select Linear, and set the Total pts to 1, Start In the textīox for each IPRINT set AC, MAG and PHASE to YES.

In series in each loop to write the currents in the output file. The coupling value is the coefficient of mutual coupling, which must be specified between Parameters to be specified are L1, L2, … up to L6, whose values must be set to Used to specify the mutual coupling between two or more inductors. The schematic until the desired dotted node is the first entry in the Netlist. Net list and if the left node is not the dotted side, rotate the inductor in The dotted terminal is always referred to the first node of the inductor () rotates the inductor +90deg, which makes this pin the one at Placed without rotation, the “dotted” pin is the left one. When the inductor symbol, L, is taken from the part library and is The dot is always next to the first pin to be “dot” convention for the coupling is related to the direction in which the PSpice uses the coupling coefficient to describe the coupled (c) Currents in the D -connected loads areĭetermine the magnitudes and phase angles of mesh currents in (b) Currents in the Y-connected loads are: The output files contain the following values for the The Schematic and the Netlist are shown in The Y-connected load inductance per phase is The line isĮnergized at the sending-end from a 3-phase balanced supply of line to neutral The second load is delta connectedĪnd has an impedance of 60 - j45 W /phase. The line feeds two balanced three-phase loads that are connected inĪnd has an impedance of 30 + j40 W /phase. Power factor frequency, f = 400 Hz, P = 4 W Series resonance frequency where reactive power is zero. Plots we see that the circuit changes from capacitive to inductive at the Using the Label command you can add text, lines and arrows to the plot. You can selectīetween different plots by holding down the control key while pressing the Located are displayed on the lower right hand of the screen. Using the cursor command you can move along Trace add the power factor with the Trace Expression as given by (4). Using Add Trace plot P and Q with the trace expressionsĬontrol, select plot and down key to switch to the lower graph and using Add To change the frequency axis scale to 350 450 Hz. Select Plot control and Add Plot to create two graphs on the Obtain one graph showing real and reactive power supplied by the source andĪnother graph showing power factor as a function of frequency. Sweep the source frequency from 300 Hz to 500 Hz in steps of 1 Hz and Probe to Power axis and add the traces with Trace Expressions asĨ*MAX(I(R1))*MAX(I(R1))/2, and 6*MAX(I(R1))*MAX(I(R1))/2 to display P and Q.Ĭircuit shown, use PSpice and Probe to graph the real and reactive powersĭelivered to the circuit as a function of frequency. Power can be expressed as, and the reactive power as Instantaneous power p (t), (in probe for trace expression type V(1)*I(R1)). Repeat to add the Y-axis and the trace for the In Probe plot the instantaneous voltage V(1), and from Plot add Y-axis and The reactor inductance isĪnalysis, set the final time to 16.6667 ms, and the Step Ceiling to 0.01 Circuit shown, use PSpice and Probe to graph the instantaneous voltage, currentĬurrent in the inductor is given to be -10.1826 A.
