Decentralized power converters coupled in series and parallel to cells (2D - 2 Dimensional) have been focused on research and application deployment. The method of implementing decentralized power converters is seen as a multi-level modulation technique. Implementation of this technique will allow dynamic modification of the system's structure when it is necessary to add or remove some cells; This is necessary in case of cell failure or optimization of a certain operating condition. This paper introduces the 2D structure and control technique according to the carrier pulse width modulation method (CPWM). Decentralized carrier phase angle interpolation (DCPAI) method for 2D structure, each cell in the 2D structure will communicate with neighboring cells to transmit and receive the necessary information for the phase shift carrier generation process. The carrier of each cell will be interpolated from the following information: position of cell in a row; position of cell in column; number of active rows and columns. Automatic carrier phase angle correction, proven parallel branch current balancing under normal start-up and dynamic reconfiguration are important issues. The proposed structure and control method are evaluated through simulation results on Matlab/Simulink software.
