Switching and Conduction losses of MOSFET

Hey,

I have simulated a 3-Phase inverter, does ee_getPowerLossSummary Function provides accurate losses, and the losses which are calculated using ee_getPowerLossSummary are total losses of MOSFET (Switching + Conduction) or just those are switching losses? IF those are only switching losses, is there any other function or method to calculate conduction losses?

Thank you in advance.

lossesTable = ee_getPowerLossSummary(node) calculates dissipated power losses and switching losses for semiconductor blocks in a model, based on logged simulation data, and returns the data for each block in a table.

These blocks in the Semiconductors & Converters library support the calculation of switching losses and reverse recovery losses, when applicable:

• Diode
• N-Channel IGBT
• GTO
• IGBT (Ideal, Switching)
• MOSFET (Ideal, Switching)
• Thyristor (Piecewise Linear)
• Half-Bridge (Ideal, Switching)

The ee_getPowerLossSummary function calculates average losses for each block that has a power_dissipated variable.

The accuracy of the computed losses will be influenced by the level of fidelity of the physical network analyzed.

Thanks for responding

Could you tell me which equation does this function use, because I have come across few switching losses equation, just want to make sure?

Thank you!
