Hi,

I am trying to run a half bridge circuit simulation in LTspice with customized Gate Driver. I am using C2M0025120D ( downloaded from Cree website).
But it shows an error called "Time step too small trouble with body diode instance". I can not figure out what is the issue.

I have attached the simulation circuit(New Simtest) in the thread. I have also included the switch model.

*** If I run the simulation for three phase case (New Sim), it works fine. But it doesn't work when i remove the two phases and the gate drivers.

Please extract the .rar file and
Drop the .lib files in C:\Program Files (x86)\LTC\LTspiceIV\lib
and .asy files in C:\Program Files (x86)\LTC\LTspiceIV\lib\sym

My LTspice collection includes a simplified transistor model C2M0025120D. This model does not take into account heat (the parameters do not change from the load), but dramatically simplifies the calculation. I made the model myself, adjusting the characteristics to the factory model.
