State discontinuity after switching after runing

General

I build the chb model, thne I replaced the A4 mos into the igbt. When I running the model, it shows the error: State discontinuity after switching.

The current through inductor [CHB_Op/L1](component:C:/Users/95438/OneDrive - University of Connecticut/Uconn All/Research/CHB Plecs/CHB_Loss/CHB_Op.plecs/L1) is forced to jump from 0.478556 to 0.
Can you help me solve this problem?

I often meet these problems. Sometimes I add on resistor in IGBT. But now it doesn’t work.

NOTE: Please include any thermal description XML files with your model in the future.

It’s not clear what your issue is from the model you provided as that runs fine as is (once thermal models are gathered). Can you upload a version that is in the state that demonstrates the issue, or show screenshots where it’s clear what change you are trying to make?

Sometimes occurs the error: forced to jump from 0.478556 to 0.

We are familiar with that of course, but it’s most helpful if you can provide a snapshot for exactly when this happens if you can re-post another version of the model that demonstrates this.

I’ll also refer you to our User Manual/inbuilt Help Documentation in the section: PLECS Help + Using PLECS + Error Messages + State Discontinuity where we discuss this and provide some suggestions for mitigation:
