Hi everyone,

Does anybody have a simulation file of 3-phase inverter where switching and conduction losses of switches are estimated?

Best regards,

Mohsen

Hi Mohsen,

There is a PLECS demo model called “Three-Phase Grid-Connected PV Inverter” which uses the thermal domain to model switch losses. You can access it in the PLECS Documentation.

Kind Regards
