Hi,
I'm new to this forum (and forums in general). I am starting my second year of engineering school (midlife career change) and have a problem I have been trying for figure out, on and off, for about a year. With an unregulated 35VDC input I am wanting to use a MCU (ESP32 specifically) to regulate voltage and current. I can find loads of voltage and current regulation circuits, however none seem to be easily adapted to run on PWM signal or a variable voltage from a DAC.
I am considering trying to make a simple buck converter and hit that with PWM to get my variable voltage. Then for the current regulation maybe the ADC into a BJT or something, but then I'm worried about response time...
I have even considered how cool it would look with a few motorized slide potentiometers on the top of the thing.
Any advice or direction would be greatly appreciated!
