Hello,
I created SPWM (Sinusoidal Pulse width modulation) and THIPWM (Third Harmonic Injection Pulse Width Modulation) modulation in Simulink:
SPWM:
THIPWM:
THIPWM and SPWM work good. Now I have to create DPWM modulation.(30-degree DPWM,60-degree DPWM. 120-degree DPWM -DC clamping, 120-degree DPWM +DC Clamping), but I have no idea how to do it. Has anyone can exemplary models DPWM in Simulink or can help me?

Input values are Ura Urb Urc
you should inject Uz to get the DPWM.
Umax = max(Ura,Urb,Urc, Umin=min(Ura,Urb,Urc)
Try DPWM2,3.
