Questions and Answers - Fall 2013


Question: I am trying to create a three-phase source for use in my simulations. I can't find such a source in the library. How can I do this?

Answer: On the Component menu select Analog Primitives / Waveform Sources / Voltage Source. Place three of these in your circuit. Ground the three negative sides. Double-click on each source and assign your preferred amplitude. Assign a phase of 0 to the first, 120 to the second, and 240 to the third. Phase is in degrees. That's all there is to it. Here is what the circuit and its simulation looks like:
