I am trying to simulate a three-phase inverter in Matlab/Simulink.
So far I figured out that in the Simulink library there are two types of inverters. The first one is illustrated in the figure below and its called "Universal Bridge"
The second type of converter is called "Three-level neutral point clamped (NPC) power converter" and you can see it below.
The main difference between the two topologies is that in the NPC converter there is one more output at the DC side. I have read that we can use this output to create one more voltage level. Also, the design methodology and the control techniques are pretty much the same.
So, I would like to ask if there are any more differences and why should I select the one topology over the other.
