Hi everyone! I have recently made a 555 timer pwm for my hho dry cell. It is supposed to deliver 12v, but when i connect it to the cell, on full power, the voltage drops to around 10V and the cell does not go to full potencial. Without the pwm, at 12v the cell consumes around 43A, but with the pwm because the voltage drops, it only goes to around 24A, and i wanted it to go from 0 to the full 43A. Is there something i can do in the pwm circuit to decrece that voltage drop? Higher frequency maybe? Btw, the main PS is a hp ps-3701-1, 12V 60A.
