ABSTRACT:
A unique multi-output isolated buck DC-DC converter system is disclosed. The converter system has non-pulsating input and output current waveforms. The converter can be adapted to two- or three-bobbin integrated-magnetic embodiments, or in discrete-magnetic form. One embodiment of the converter comprises capacitor means joined at one end to a first common core inductor and joined at its opposite end to a second common core inductor; and switch means having a duty cycle, for alternately joining an output lead to one end of the capacitor means and to the opposite end of the capacitor means, such that a voltage proportional to "VD" is produced at the output lead when a DC voltage "V" is applied across opposite ends of the first and the second common core inductor.
