PSIM Tutorial by Dr. Woonki Na, ECE, Bradley University

Go to http://www.powersimtech.com/index.php?name=download

and download the free demo version. Also you can download the PSIM user manual from the

website.

And run the PSIM icon and you could see the below figure.

Choose the new from the file section.

You can see the white blank screen.

Lets do a simple diode rectifier example.

1. First, we have to find circuit elements for the circuit that we would like to design.

For example, for the diode rectifier case, we just need source, resistor and diode.Lets find the source(AC ). Go to the elements section and then choose sources and

voltage and sine like below screen Fig. 1.

Once choosing the sine tool bar, the sine voltage source is created as below Fig. 2

Fig.2

And letsfind the resistor . Like the same manner we found the source in Fig.1, go to the

elements section and choose power and RLC branches and resistor as Fig.3

Fig. 3

Now the resistor has been added in Fig. 4

Fig. 4

Finally, the diode can be added almost in the same ways we found the source and the resistor in

Fig. 5. In the elements, choose the power and switches and diode sequentially.

Fig. 5

What do we miss in the circuit ???

Yes, we need a ground. Simply ground can be found on the tool icon in the left bottom in Fig. 6.

Fig. 6

By double clicking the ground icon in the left bottom in Fig.6 and all four circuit components areready to build a rectifier circuit in Fig7.

Fig. 7

Using the tool icon, the wire, we can connect all these circuit components in Fig.8.

Also you can move each circuit component with mouse and rotate it by choosing the edit sectionin Fig. 9

Now really ready to run the circuit in Fig.10. Well, I guess we miss something. Yeah, we have to

define the value of each circuit component.

Fig. 10

By double clicking the source, there is a small popup window to set the parameters for the source.

Now I just set 220V peak and 60 Hz, but you can change as you want in Fig11.

Like the same manner, we can change some values of parameters of the diode in Fig.12. Fig.12 I

just set 0.7 as diode threshold voltage, kind of constant voltage we learned in the class.

Fig. 12

Double clicking the resistor and then I set the value of the resistor as 1000(1K) ohm in Fig.13.

Fig. 13

To see the waveform specially, the output voltage across the resistor, what do we need? Yes, we

might need a scope to see the waveform. Just double click in the mid of the bottom, one of the

icons, probe and place the location where you desire to see in Fig. 14.

Fig. 14

Finally everything is really ready to run this circuit, just click the run simulation icon in Fig. 15

Fig. 15

Once click the run simulation icon, automatically a small window is popped up in Fig.16. This is

the output voltage waveform. Since this PSIM version is just a free edition, there are a lot of

limitations for the professional uses such as limited components and limited simulation time.Any way this is very useful to learn and understand basic circuit theory. This output is just for 60

Hz , 220V peak voltage source and you can try it with other voltage source values. In the case of

600Hz and 220 peak voltage source, the output voltage across the 1K resistor is shown in Fig. 17.Is that almost the same as the waveform we learned in the class?

Fig. 16.
