In this dissertation studies regarding the modeling of the interleaved converter with a generic number of phases and their main operational characteristics are discussed. This converter is used in order to perform power interface between the DC links of a hybrid microgrid. Linear control techniques found in the literature are presented. From this study a new control law based on an adaptive state feedback and on a feedforward technique is presented. Aspects related to the robustness, control project and stability analysis of the research techniques are presented. In addition, a study on the use of predictive control in this type of converters is carried out and it is proposed a new strategy of this class of controllers. The presented results confirm the theoretical studies developed throughout this work, validating the proposed techniques in several scenarios of system operation.
