    Hello Minoru,

    I hope you are doing well.

    Sorry for the late reply.

    Please find attached a new version of the model with the following modifications :

    • Changed inverter power supplies polarity
    • Changed inverter switches polarity , Ron/Roff and thresholds
    • Changed the solver type to Radau-IIA as advised by Activate to allow constraint error correction

    The simulation runs fine now :
