PSIM simulation for three phase motor inverter.
How to find the loss of IGBT in simulation. Should I check average loss or RMS loss ? Also, if inverter output power is to be calculated in simulation, then below formula is used. If I plot above formula in Simview I get below results - S10.ploss_total, S15.ploss_total, S16.ploss_total are the losses in each IGBT half…

Simcoupler for Simulink returns 0
Hello all, first time writing. I am triying to run a PSIM model from Simulink. For that I am using the Simcoupler block. It seems to simulate perfectly, no errors or warnings are prompted, but it returns 0 in all ports. I am working in MATLAB 2025b 64bits and PSIM is the 2022.1.0.8 64. I have tried other previous MATLAB…

Feedback – PSIM Student License System
Hello, I’d like to share some honest feedback: the current AltairOne student license process is incredibly frustrating. It locks to a single Host ID, offers no self-deactivation, and constantly breaks after password changes. Please consider simplifying this for students — we’re wasting hours just trying to use the software.
