Abstract: A high-power, switched-mode power conversion array having an input capacitance, an output capacitance, and a multiple, reconfigurable converter cells. Each of the converter cells convert an input voltage to an output voltage using switched-mode power conversion. The converter cells operate at a conversion frequency and are phase-shifted across one conversion period, so that each converter is switched ON in a time-overlapping relationship with at least one other one of the plurality of converters. As a result, the input and output current and the voltage ripple are substantially reduced, the ripple frequency of the array is increased, and the power capacity is increased. The converter cells can have a selectable conversion frequency, and thus, a selectable period. The apparatus also can include a programmable interconnection network selectably and reconfigurably connecting each cell to at least one other cell, an input node, or an output node, using serial or parallel connections.
