Hi Plecs team,
I am fairly new to plecs and I have developed a three-phase, two-level inverter in PLECS using sinusoidal PWM. For the loss and thermal analysis, I am using the Fuji Electric IGBT module 7MBR50VD120-50, with the IGBT and diode thermally modeled based on the parameters provided in the datasheet.
After performing the steady-state analysis in PLECS, I calculated the conduction and switching losses and compared them with the results obtained from the Fuji Electric online simulator under what I believe are equivalent operating conditions. However, I am observing a significant discrepancy between the two sets of results.
I would appreciate any guidance on what aspects of my PLECS model might need adjustment (for example, device parameters, switching loss modeling, modulation assumptions, thermal setup, or operating conditions) in order to obtain loss values that are closer to those reported by the Fuji Electric online simulator.
attaching the simulation and xml files for reference
Thank you very much for your time and support. Any suggestions or best practices for aligning PLECS simulations with manufacturer-provided simulation tools would be greatly appreciated.
Best regards,
Yashaswini
