Hi, I have previously tried asking this question to no avail, However this time i have simplified my question and come at it from another angle.
Most cheap PWM circuits for controlling heavy dc loads (10amps plus) Have only duty cycle control with a fixed frequency. I want to add an external signal generator to supply frequency control to the PWM. So to summarize im just trying to largely amplify a signal generator's signal.
I may be using multiple PWM's in parallel to reach my target amperage of 250amps.
Here's an idea of the PWM and signal generator
Kind regards
