Magnetic-free DC/DC converters, methods of operation thereof and a computer system employing at least one converter. In one embodiment, the converter includes: (1) an input capacitor coupled to a DC input of the converter, (2) a first switch coupled between the input capacitor and an output of the converter to transfer electrical power from the DC input to the output when the first switch is closed, (3) an output capacitor coupled in parallel with the output of the converter, (4) a second switch coupled in parallel with the input capacitor to short the input capacitor when the second switch is closed and (5) a switching controller circuit, coupled to the first and second switches, that provides complementary control signals to the first and second switches that are a function of an output voltage of the converter.
