PIC Based PWM for Hydrogen Production

I designed a microcontroller based PWM, that will automatically limit the current on your HHO cell. It was based on a PIC16F877 IC. I wrote the code for it in PICBasic.

The PWM will have:

  • Adjustable Duty cycle
  • Adjustable frequency 1300 to 23000 HRz
  • Automatic current limiting when a preset boundary is reached
  • LCD screen add on to visualize all the above and MORE!!!!
  • Easily upgradeable and expandable
  • 150AMP continuous use rated!!!!!!!! (if you need that many amps…LOL)
  • Lots of other things too…..
  • “Set it and forget it!”

Here is a 3D image of the board (with out LCD).
