A Current Sharing Method for Paralleled DC-DC Converter with Parameter Estimation
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 7
Abstract
In this paper, a new current sharing technique on a general case of N paralleled DC–DC boost converters is presented. The proposed optimization is based on the knowledge of individual boost parameters. Every loss through the structure are modeled by equivalent resistors. Using an accurate online estimation of those resistors, the losses through each individual converter can be determined. Then, a new current sharing scheme is defined aiming to maximize the global efficiency of the overall structure. To verify the proposed method, simulations and experiments have been realized on a three-parallel boost converters structure.
