Need help for IGBT parameter in PSIM

[jagodzzinski]

hello I am jagodzziski from poland i would like to ask u about PSIM software actually I am doing single phase SPWM inveter voutput 12V 50HZ .. may i know what parameter for igbt and may u show me the calcultion tq

Hi, jagodzziski. I guess none of us use PowerSim. So, I cannot help you with the software. I personally use OrCAD PSpice.

As for IGBT, are you asking for model parameter or a specific model?
If you have planned a specific model please mention it. I'll try to solve the circuit for you.

ooh really ..hmm I am not familiar with that software but mine share ur single phase inverter cct that produce spwm..btw thanks for ur rply mr Kholdstare ..sorry for my bad eng.

hey jag, download LTspice (its free). then you can get spice models for IGBT's on fairchild's site:

Hello jagodzziski,

Thank you for reaching out for help with PSIM software. I am not an expert in PSIM, but I can provide some general information about IGBT parameters and calculations.

IGBT stands for Insulated Gate Bipolar Transistor, and it is a type of semiconductor device commonly used in power electronics for switching and amplification. The important parameters for IGBTs include the maximum voltage, current, and power ratings, as well as the switching frequency and gate drive voltage.

For your single phase SPWM inverter with a 12V 50Hz output, the IGBT parameters will depend on the specific design and requirements of your circuit. Some factors to consider when selecting IGBT parameters include the load, input voltage, switching frequency, and desired efficiency.

To calculate the IGBT parameters, you will need to determine the maximum voltage and current that will be present in your circuit, taking into account any safety margins. You will also need to consider the power dissipation and thermal requirements for the IGBT to ensure it can handle the expected load and switching frequency.

I would recommend consulting with a power electronics expert or referring to the datasheets of specific IGBTs to find the appropriate parameters for your circuit. Additionally, PSIM may have a built-in tool or tutorial to help with IGBT parameter selection and calculation.

I hope this information helps you in your project. Best of luck with your inverter design.
