Hallo!

Ich bin zur Zeit mit MMC beschäftigt und möchte einen Three Level Half-Bridge MMC (single phase) simulieren. Die Schaltung habe ich schon fertig.
Das Problem ist, dass die Ausgangsspannung (ULast) nur positiv ist, offensichtlich liegt das Problem an dem negativen Zweig (unterer Submodul).
Können Sie mir bitte dabei helfen.

Mod: translate, please use English text.

I'm currently working with MMC and would like to simulate a three level half-bridge MMC (single phase). I have already finished the circuit.
The problem is that the output voltage (ULad) is only positive, obviously the problem is on the negative branch (lower submodule).
Can you please help me with this.
