I used the infineon IPOSIM power tool for simulating a motor drive for my required conditions and got the results for a custom input drive cycle.

The results were given as power dissipation per IGBT(IGBT Switch) i.e, P_switch and Power dissipation per diode i.e, P_diode.

If I am using one IGBT dual Model and three modules in total to realize a 3 phase 2 level motor drive, then, what should be the multiplying factor for the total power dissipation?

Since, it is a SVPWM drive with three switches remaining ON at any point of time, so what should be the max power dissipation in this case according to my inputs? Should the Multiplying factor be 3 or 6?

Asking this to have a clarity of my concepts!
