How to write an Converter/inverter model
I want to build an inverter model with three-level bridge and use SVPWM to control it. But I couldn't find IGBT or others. 
I read model REGCA1 in MODEL.pdf, but I feel it helpless. 
Could the inverter-bridge structure be implemented in PSSE? And how to control it. 
If not, how to bulid the model?
Thanks.
