Hybrid Space Vector Modulation Scheme for the Multiport Hybrid Converter

This work proposes a hybrid space vector modulation (HSVM) scheme for multiport converters (MHCs). Moreover, the impact of shifting auxiliary currents from main ones is proposed and investigated in order to enhance converter efficiency. The operational schemes have been implemented three-phase 5 kW MHC prototype. It shown that HSVM can improve efficiency by 0.3% at full load with respect modulation. At partial loads, improvement even more significant, reaching +0.7% 30% rated power. A further 0.15% increase power be achieved 180 $^{\circ }$ phase terminal currents, peak 98.5%.
