ABSTRACT:
A method for converting power includes charging an inductor by coupling the inductor to a voltage source for a predetermined amount of time. Thereafter, the inductor is discharged by coupling the inductor to a ground until the current flowing through the inductor equals zero. A method for detecting a zero current flowing through the inductor includes coupling the inductor to a transistor and comparing the output of that transistor to a transistor coupled to ground.
