As an illustration, the example above shows the losses calculation of a Powerex discrete diode.
1. The diode conduction losses and switching losses are calculated separately. With the thermal equivalent circuit, the heatsink, case, and junction temperatures are calculated.
2. The waveforms show the diode currents, conduction losses and switching losses, and the junction temperature.
3. The Device Database Manager and the diode forward conduction characteristics are also shown.

Loss calculation is an important aspect in power converter design. Traditionally, users rely on the physical device models from the device manufacturers or software vendors. But the model of a particular device that is of interest may not be always available.
With the Thermal Module, users can easily add devices of any manufacturers into a database and use these devices in the simulation for loss calculation. With the loss information, one can build a thermal equivalent circuit and calculate temperature raise.
One major advantage of the Thermal Module is that it is very easy to use. New devices can be easily added into the database.
Utilities are provided to capture the curve of a characteristic directly from the device datasheet image. Also, the Database Manager provides convenient ways to navigate through the database and search or sort devices.
Another advantage of the Thermal Module is that the loss calculation is done in such a way that it does not compromise the fast simulation speed of PSIM.
With the calculated losses, users can then implement the thermal equivalent circuit, and perform the thermal analysis to calculate the device temperature raise.
The Thermal Module is ideal for quick loss estimation, and for comparing different operating conditions and comparing devices of different manufacturers.
