I want to simulate AC/AC converter and I need to know how I can simulate a PWM for it , my main problem is "dead time" circuit and comparator circuit that I don't know if I have to build them or they are within PWM block?
I have found an example on youtube, this might help you

The gating pattern for PWM signal is done based on modulation index. When the synchronization signal changes the gating pattern is enabled. The delay angle defines the relation between gating pattern and synchronization signal.
Daer Sepehr Didevar,
The simple way generating PWM with dead band is: as follows-
Suppose you wish pulses (say S1 and S1_bar) of duty 'd' and with deadband.
Generate a pulse of duty '(d-0.5*td)' -> this is pulse S1, td= dead band
Now generate a pulse of duty '(d+0.5*td)' -> take is compement -> this is pulse S1_bar.
Enjoy......!
