When using PLECS 4.7.4 software to perform thermal simulation on the inverter, I found that the temperature of the device would continuously rise to infinity. However, I removed the relevant settings for thermal simulati… --- ## [Storing and plotting data across a simulation script](https://forum.plexim.com/t/storing-and-plotting-data-across-a-simulation-script/1180)

Hello, I’ve been using PLECS for thermal simulation for a while and still confused about the temperature units. I fully understand that the scaling is the same to Kelvin and Celsius, but when I read the data from a Prob… --- ## [Problem with using controlled current source](https://forum.plexim.com/t/problem-with-using-controlled-current-source/1003)

I have a problem using a controlled current source. I would like to measure the temperature of a motor part using heat loss and power. I have seen that this way is good because at certain points it will limit the tempera… --- ## [Thermal domain Kelvin or Celsius temperature](https://forum.plexim.com/t/thermal-domain-kelvin-or-celsius-temperature/1001)

Hello Users I’m using an IGBT switch with thermal model and connected to a reference temperature (e.g. Ambient) via an RC foster network. I want the IGBT to start from higher temperature than the ref. I tried to let the… --- ## [Hi, How I can keep the case temperature of an IGBT to a constant value?](https://forum.plexim.com/t/hi-how-i-can-keep-the-case-temperature-of-an-igbt-to-a-constant-value/748)
