Have you decided not to use the circuit using a 555 and an op-amp I gave you, or are you exploring?Hi sir.. thank you so much for your effort ^_^ but I need an Osc. with variable duty cycle for that reason the output voltage of the invertor will compensate for battery voltage variation (i.e. 13.8V to 11.8V). I came-up with an idea of using PWM Controller IC such as TL494 or SG3524, etc.
What PWM controller IC (as Oscillator) do you think is well-suited in building this linear type MSW invertor together with CD4017 decade counter? ....TL494? ....or Sg3524/25?
