Abstract
DC–AC input-series-output-series (ISOS) systems are very suitable for high input voltage and high output voltage power conversion applications. The implementation of the compound balanced control strategy is presented for the DC–AC ISOS system to achieve input voltage sharing (IVS) and output voltage sharing (OVS). The output filter inductor current or the output filter capacitor current adopted as the feedback signal for the inner current loops of each module, respectively, is analyzed and compared. Taking the output-filter-capacitor-current method as an example, the decoupling relationship between the control loops is analyzed and the loop design procedure 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 system.
