In this paper, the modified decentralized modulation for the control of multiphase converters using phase-shifted carriers is presented. In difference of principle using local interconnections from two neighbor independent elementary controllers in the conventional decentralized control, the proposed method uses local informations from only one neighbor independent elementary controller allowing them to self-align their own carriers regardless the number of actives cells. Moreover, the same principle is applied for decentralized current control in the parallel phases in order to achieve a perfect sharing of the output current. The simulation results show the feasibility and effectiveness of the proposed method.
