This digest presents a modified virtual Space Vector Modulation (SVM) strategy enabling flexible power sharing in ten-switch dual-source inverters (DSIs) for photovoltaic–battery systems. The ten-switch topology reduces switch count and losses but cannot synthesize certain vectors required by conventional SVM. The proposed method introduces topology-compatible virtual vectors, detailed region detection, and systematic mathematical formulations for dwell time calculation, overcoming limitations of prior work. Vectors are classified into non-zero, pseudo zero, and zero power delivery categories, revealing that pseudo zero vectors do not contribute to net power allocation. Experimental results for different modulation indices confirm balanced currents, correct power distribution, and compatibility with the topology’s voltage constraints. The method supports dynamic adaptation to DC source variations, improving applicability in real-world hybrid energy systems.
