Question regarding mosfets... (sorry, i'm a computer engineer, that's like electrical without any analog electronics but more programming and logic...) Their output current is relative to the input voltage, nay? Why PWM in a high voltage at a variable duty instead of provide a variable voltage? Is it something to do with the efficiency of the mosfets? Aren't there switching losses or something in PWMing a mosfet?
