It functions to change a fixed DC input voltage (V s )into a variable DC power or output … WebApr 25, 2016 · Because you are chopping at high frequency, the current will be smoothed by the inductance of the winding (which is what we want). So it is actually the average voltage (depending on the duty cycle) divided by the resistance. Therefore, if you have a 50% duty cycle, this makes 6V (not couting the losses), and you'll have a current of 1.5A.
