Abstract

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