CURRENT SOURCE IN PSPICE SCHEMATICS SERIES
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.

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 IPWL, IPWL_ENH, IPWL_FILE, IPWL_RE_FOREVER, IPWL_RE_N_TIMES, IPWL_F_RE_N_TIMES, IPWL_F_RE_FOREVERįor details please refer solution 11786012įor details please refer solution 11094668Īlso of interest: Part Properties in the PSpice Help defines all of the user-defined properties on the PSpice schematic parts, and is a help to know which properties to set on the xPWLx symbols in the SOURCE libray.Circuit shown, use PSpice and Probe to graph the instantaneous voltage, currentĬurrent in the inductor is given to be -10.1826 A. If you want to describe a current source, by entering time-current data, use the analogous parts: REPEAT_VALUE - Number of times to repeat the PWL waveform Where "pwl.txt" is a file in the design directly. VSF - Voltage scaling factor (multiplies voltages specified) TSF - Time scaling factor (multiplies time values specified) REPEAT_VALUE - Number of times to repeat the specified PWL waveform THIRD_NPAIRS - Third line containing PWL pairs, to be concatenated with SECOND_NPAIRS SECOND_NPAIRS - Second line containing PWL pairs, to be concatenated with FIRST_NPAIRS. These are voltages corresponding to the simulation time values.įIRST_NPAIRS - First line containing PWL pairs, i.e. The following are schematic parts that can be used, along with their property definitions: The piece-wise linear voltage sources allow you to describe a transient voltage waveform by connecting time-voltage pairs, which you define.
