Abstract
The inherent relationships between the sharing of input voltages/currents and the sharing of output voltages/currents are analyzed systematically from the view of power conservation in this chapter, and the stability of various possible control strategies is discussed. Based on the analysis, a general control strategy is proposed for the DC–DC series–parallel power conversion systems, which not only achieves equilibrium between the constituent modules but also decouples the output voltage control loop and the sharing control loop. Furthermore, a modularization architecture for the DC–DC series–parallel power conversion systems is proposed, achieving full modularization where all the modules are self-contained and standardized, and no extra control is needed to achieve sharing of voltage and/or current at the input and output sides. Experimental prototypes are built and tested to validate the proposed general control strategy and the modularization architecture.
