DISTRIBUTED INTERLEAVING OF PARALLELED POWER CONVERTERS

This paper introduces a distributed approach to interleaving parallele d power converter cells, Unlike conventional methods, the distributed approach requires no centralized control, automatically accommodates v arying numbers of converter cells, and is highly tolerant of subsystem failures, A general methodology for achieving distributed interleavin g is proposed, along with a specific implementation approach, The desi gn and experimental verification of a 50 kHz prototype system is prese nted, and quantitative performance comparisons are made between synchr onized clocking, independent clocking, and interleaved clocking of the converter cells, The experimental results corroborate the analytical predictions and demonstrate the tremendous benefits of the distributed interleaving approach.
