    I created the thermal module of the mosfet, but I can't save it to the device as a file and ı can't transfer to the psim. How can ı do it?

    Can i do these steps for diode also? I can add any manufacture diode? Are these features available in psim version below 10...? How much will it cost to buy psim latest version for power electronic research

      yes you can do the same steps for a diode. the thermal module was released before version 10, you need to submit a price request to get pricing. goto the website www.powersimtech.com

    I would like to ask something concerning the module. Let's assume that we have a converter (the type does not matter). I have noticed that if we add the average generated loss to the power output, the result value is always greater than the power input (measured using a wattmeter), which is quite paradox. In other words what I mean is that Pout+Ploss>Pin. Can you explain me why this happens?

      +George Apostolou good observation, the module is not intended for an efficiency study. The switching losses generated by the module are only calculated and will not be supplied by the source. This allows for a fast simulation as it reduces the simulation points needed. The objective of the module is to help with thermal design, rather than to calculate overall system efficiency.
      For a calculation of efficiency please use the level 2 devices included in version 10.

    This is a good video/introduction to the thermal module, but comparing the results of the thermal module with the results obtained from simulation softwares of the semiconductors manufacturers (IpoSim, SemiSel...), they never seem to match.
    With this in mind, I question, is the goal of the thermal module to give a broad and general idea of the thermal losses or to be an accurate and crucial part in the design of power electronic applications?

    • @altairhowto

      Thank you for your comment!
      The goal of the Thermal Module is to generate power loss results that provide a general idea but also are accurate enough for power converter design. For one test case, PSIM and IpoSim's switching losses are within 8% of each other, and the conduction losses are within 1% of each other.
      There is an IEEE published paper that compares PSIM Thermal Module results with experimental results, and finds that the PSIM results are within 10% of the experimental results.
      If you would like a more detailed analysis or a list of published paper references please contact our support team directly. This can be done on our website through the Support Request form, or directly in an email to support@powersimtech.com

      PSIM, thank you very much for the reply.
      I have to say in my experience, the thermal module add-on has been a good learning tool, proving to be very useful in that regard. But now I need it to a more real life application and I'm finding it somehow limited.
      For instance in an IGBT it doesn't consider the energy recovery of the transistor like in SemiSel. Also, it doesn't allow me to add other topologies like the SKiM301TMLI12E4C module which i'm thinking of using for a T-Type Inverter.
      This last point is rather frustating since currently I'm researching on the power losses of different topologies of inverters and boost converters, and can't find a flexible approach within or with PSIM.
      So with this in mind, is there any update in the foreseeable future for the thermal module, or do you have any tips that I can use in my design simulations?

      Can you please clarify what you meant by “energy recovery of the transistor” (which quantity is it in the datasheet)?
      As for the device SKiM301TMLI12E4C or any other topologies that we don’t support at the moment, you can always enter the device as a single discrete device into PSIM’s Device Database. Then use multiple elements of the discrete device and connect the circuit in the same way as the original device. The thermal nodes of the discrete devices can be joined together through their respective junction to case thermal impedances to simulate the effect of being in the same package.
      In short for an unsupported topology use the supported discrete devices and connect them appropriately electrically and thermally.
      Does this answer your question?

      I've applied your recomendations and comparing with other simulation softwares, the thermal module seems to be in the error range that you specified (though I don't think this can be used to every topologies).
      Thank you very much.

    I have a question, let say if the simulated circuit characteristic such as the collector current appear to be larger than a device's maximum collector current, will error appear for loss simulation or will it continue simulating with wrong losses value?

    • @altairhowto
      @altairhowto  6 лет назад

      if the input data does not include the value that you are simulating, PSIM will extrapolate which will likely give you clearly wrong results. As the designer you need to review the waveforms to make sure everything makes sense.. This is why you'll make lots of money when you are in industry, by being thorough in your designs and doing careful review of any data.

    why the ambient temperature selected to be 75?

    • @altairhowto

      +Abdulaziz Alkuhayli No particular reason, the ambient temperature needed to be something.

      it could be aleatory?

    • @altairhowto
      @altairhowto  6 лет назад

      @@nihadaghbalou9806 completely random is not helpful, typical ambient temperature ranges could be 10-100 dC depending on environment. Typical max temperatures for junctions are in 150 dC range, so any thing hotter than this is not really useful.
