This paper presents the study of a high dynamic current control strategy using the decentralized principle for a parallel multiphase converter. The control of the output current by the use of stacked equivalent carriers allows to obtain very fast dynamics while the use of decentralized local control provides robust balancing of the currents in each phase. Each phase regulates its own current simply and only by using information from neighboring cells. The first part of the paper will present this high dynamic control of output current then in the second part the decentralized principle will be used for the PWM generation and balancing of the currents in the parallel association of the converter cells.
