    Hello.
    I tried to simulate a pwm generator which deliver the signal to a six phase interleaved buck converter.
    I'm stuck at the phase shift for the 60, 120, 180, 240 and 300 degrees. I made the conversion from phase shift in degrees to time at switching frequency of 100 kHz, and used transport delay blocks, unit delay and variable time delay.
    In the picture attached, i have the phases delayed corresponding to 60 and 120 degrees, but it's not working ok.
    Any opinion will be appreciated. Thank you
