single phase 3 level H-Bridge inverter, 5 level H-Bridge inverter, 7 level H-Bridge inverter in Psim

HI

I would like to design single phase 3 level H-Bridge inverter, 5 level H-Bridge inverter and 7 level H-Bridge inverter in Psim , but I have problem I do not know how can take the value for angle in every level, any one can help me?

5 level H-Bridge inverter

5 level H-Bridge inverter waveform





this is my circuit 5 level H-Bridge inverter
