Re: Problems in syncing MCPWM output for dimming purpose
So if my duty resolution is say 60%, then my MCPWM should fire the TRIAC on the zero crossing optocoupler interrupt for 6 ms (60% of 10 ms) and then close the triac gate for the remaining 4 ms till the next interrupt comes and this process is repeated forever. I posted that drawing because you have...
