- Simscape Electrical has PWM Generator(Multi-level) blk. : https://www.mathworks.com/help/physmod/sps/powersys/ref/pwmgeneratormultilevel.html?searchHighlight=mmc&s_tid=doc_srchtitle This generates multi-level PWM signals.
- You can refer to the 'Modular multi-level converter' at : https://www.mathworks.com/help/physmod/sps/ug/modular-multi-level-converter-mmc.html?searchHighlight=mmc&s_tid=doc_srchtitle Your left circuit is similar with MMC, so please visit above example.

How do I generate pulses from the block PWM Generator to operate the switches if they are more than four?

Hello every one 
I hope to find any ideas for my inquire. 
my question as in the picture there are two models, the left one five-level cascaded with PWM pulses to operate the switches, and the right one is a boost converter with a 
PID  controller to operate one switch. so here  I want  to  use  PI control to on five-level cascaded model  but  after PI block 
How do I generate the pulses for 8 switches to operate them?

        As answered on your other question by Joel. If none of the above workarounds help you, you will have to write your own algorithm to convert the scalar output into separate duty cycles.
