Originální abstrakt

This article is dealing with paralleled three DC-DC converters in 6-phase operation. Paralleling commercially available DC-DC convertors to achieve high current capability can be a challenging task. The main problem is the way how the sensing of output current is solved and thus the current sharingmay be problem. Using series diode at the output, or finding correct load sharing circuit may help, but functionality of load sharing circuits can be used only with certain convertors. Main function of these three paralleled current controllers is to boost 24 V at the input to 28 V at the output with current capability up to 100 A. The aim of this document is to give an idea of a simpler way for parallelism of converters, to stress the importance of length matching, minimization of the high frequency spikes and to discover advantages of multiphase operation.
