Transformerless PV inverter-simulation

[Jiri Stach]

Hey all,

I need help with simulation transformerless PV inverter in Matlab (Simulink+PowerSIM). I had simulation HB bipolar and unipolar topology. But I dont know what to do simulation HERIC and H5 topology. Output current is not good. My problem is in switch vectors.
Can you anybody help me with it, please?. I send in attach my schematic in Matlab.


Thank you very much!

Jiri

Hey, I would suggest you to start using Stateflow. It's very convenient when it comes to complex control schemes.

I looked at your model briefly, there seem to be a lot of switches in your model. This will be difficult to test debug, and will get progressively so as your model grows. Such logic is best represented using a flow chart and state machine. Look at Stateflow videos on how to represent control logic like this, simulate and animate it to test that it works as expected here.
