Abstract
In this paper, the implementation of the compound balanced control strategy is presented for the DC–AC input-series output-parallel (ISOP) systems to achieve input voltage sharing (IVS) and output current sharing (OCS). The inductor current and the output current adopted as the feedback variables for the inner current loop of each module, respectively, is analyzed and compared. Taking the output-current-feedback scheme as an example, the decoupling relationship between the control loops is analyzed and the design of the control loops is given. The simulation and experimental results are provided to verify the effectiveness of the proposed control method. Furthermore, this chapter presents a new solution dedicated to distributed configuration on the basis of centralized control, which can improve the reliability of the systems.
