Full Bridge MMC Controller

Hello everyone,

I am developing a new project in my university and the first step is to simulate my experiment on MATLAB.

My project will be the creation of a STATCOM to inject reactive power in the grid. I am using a Statcom in delta connecting with 3 submodules per cluster. Each submodule are connected in the full bridge way, where I have 4 IGBT's to charge each capacitor.

The output of my controller is the voltage of each capacitor, but I am having problem to use this voltage to control the IGBT's.

I need a way to control four IGBT's connected in full bridge mode to reach an output voltage.

Or I can use another way to control a STATCOM.

Can someone help me out?

If someone are expert in this matter, I will be pleased to discuss further about the topic.

Thanks anyway
