Hello, I am making some modifications in my programm that had written by someone. it is about a flame machine and AC mains frequency is 50Hz. Now, the program is working for outputting a 20ms continous flame that means it is quiet clear that it was working at 100% duty cyle(not sure!). I want to make modifications in program to get atleast a continous flame for 1second or more. I think it is not possible because of it is already working at full duty cycle(not sure!) or am i missing soemthing? The signal that i am working with is PWM. Can i get any help here?
