Are IGBTs in PSIM and Multisim 7 Equivalent?

In summary, the conversation revolves around a senior at Wayne State University who is taking a Power Electronics class with a bad teacher and a difficult class structure. They are working on a project to design an active power filter for load compensation and are using the demo version of PSIM. However, the demo version is limited in the number of elements it can simulate and the person has not been able to purchase the full version. They are considering using Multisim 7, which has a full version, but are unsure if the IGBT component in Multisim is equivalent to the one in PSIM. They ask for suggestions and welcome the new member to the forum.

Hello!

Just signed up for this, my bf has been ranting and raving about it forever!

Short Intro:
Senior at Wayne State University (Detroit)...LAST ECE class! Power Electronics. Bad teacher, ridiculous class structure...you know the jist.

Doing a project for this class which is becoming completely self taught. Design an active power filter for load compensation.

So far I think I'm doing okay. I have a the demo version of PSIM, which has IGBT's that look the way I am familiar with them looking:

(not that entire thing, but the switch in parralell with the diode)

The thing is that the PSIM demo won't run a simulation with a certain amount of elements and I haven't been able to get ahold of anyone at the company to buy it. So I think I am going to use Multisim 7 which I have a full version of.

Multisim 7 shows the IGBT component as something similar to:

My question:

Are these two things equivelent?

Does anyone have any suggestions to make this work if they are not?

Thank you!
Crystal

Can you post the models for each? You can tell how close they are by the underlying text model parameters for each. Welcome to PF, BTW.

Hi Crystal,

Thank you for sharing your experience with using PSIM and Multisim 7 for your power electronics project. It sounds like you have encountered some challenges with the software, but I'm glad to hear that you are persevering and finding ways to make it work.

To answer your question, the IGBTs in PSIM and Multisim 7 are not exactly equivalent, but they serve the same purpose in simulating power electronics circuits. The main difference is in the graphical representation of the component. PSIM uses a simplified representation of the IGBT, while Multisim 7 shows a more detailed model. However, both can be used to simulate and analyze the behavior of IGBTs in a circuit.

If you are having trouble running simulations in PSIM due to the demo version limitations, I would recommend reaching out to the company's customer support team for assistance. They may be able to provide you with a solution or offer a discounted full version for students.

In the meantime, you can also try using Multisim 7 for your project. It may take some time to get familiar with the software, but it should be able to handle the simulation of your active power filter. You can also refer to online tutorials or manuals for guidance on using Multisim 7.

Best of luck with your project and your last ECE class! I hope you are able to successfully design your active power filter and gain valuable knowledge and experience in power electronics. Keep up the good work!
 

FAQ: Are IGBTs in PSIM and Multisim 7 Equivalent?

What is an IGBT and how does it work in PSIM and Multisim 7?

An IGBT (Insulated Gate Bipolar Transistor) is a power semiconductor device used for switching and amplifying electrical signals. In PSIM and Multisim 7, IGBTs can be modeled as simple switches that can be turned on and off to control the flow of current in a circuit. They can also be used in combination with other components to create complex circuits and systems.

Can I simulate multiple IGBTs in PSIM and Multisim 7?

Yes, PSIM and Multisim 7 allow for the simulation of multiple IGBTs in a single circuit. This is useful for analyzing the behavior of complex systems that use multiple IGBTs for control and power management.

How accurate are the IGBT models in PSIM and Multisim 7?

The IGBT models in PSIM and Multisim 7 are based on real-world data and are designed to accurately simulate the behavior of these devices in various circuit configurations. However, the accuracy of the simulation also depends on the accuracy of the circuit parameters and the input values used in the simulation.

Can I use PSIM and Multisim 7 to design and optimize IGBT circuits?

Yes, PSIM and Multisim 7 have built-in features that allow for circuit design and optimization. These tools can be used to design and simulate IGBT circuits, and then analyze the results to optimize their performance.

Are there any limitations to using IGBTs in PSIM and Multisim 7?

While PSIM and Multisim 7 offer a wide range of capabilities for simulating and designing IGBT circuits, there may be some limitations depending on the complexity of the circuit and the simulation parameters used. It is always recommended to cross-check the results with real-world data and perform multiple simulations to ensure accuracy.
