ABSTRACT:
A power converter is disclosed that includes multiple lower power boost converters interconnected to reduce the magnitude of the input current ripple and output current ripple by distributing the converter current draw over time, as compared to a single boost converter. The operating cycle of each of the multiple boost converters is phase shifted with respect to the others. The converter described converts a primary input DC voltage into an output DC voltage, wherein the output DC voltage is higher than the primary input DC voltage. The converter includes a primary input terminal for receiving the primary input DC voltage and a plurality of boost converter cells, each of which has an input connected to the primary input terminal, and each of which has an output. The converter additionally includes a master controller for causing each boost converter cell to operate in a predetermined phase relationship with respect to the other boost converter cells. An output filter is connected to the output of each boost converter cell for summing the outputs of the boost converter cells to produce the output DC voltage. A feedback from the converter output terminal through the master controller to each boost converter cell provides an error command to each boost converter cell to accomplish output voltage regulation.
