Answer Question
Delay block/signal for pulse-width modulation (PWM) signal?
Hi,
I am modelling a modular multilevel converter (MMC). And I have 2-level half bridge submodules with 2 IGBT (insulated gate bipolar transistor) switches inside each. When employing the PWM scheme, i would like to place a delay block between inverters so switching pattern becomes as follows:
1 (on) 0 (off) -> 0 (off) 0 (off) -> 0 (off) 1 (on) -> status of IGBT switches.
Mine goes straight from 1 0 to 0 1. How do I add that delay so it goes to 0 0 in the middle?
