“…Due to the massive growth of DC resources and DC loads in the distribution network, the demand for low-voltage DC (LVDC) ports on the MPET significantly surpasses that for the low-voltage AC ports. The LVDC ports provide efficient integration of distributed generation (DG), electric vehicle (EV) charging stations, energy storage systems (ESS), data centers and other industrial DC loads [8,9]. Since the nominal voltage of DGs and DC loads are different, an MPET with multiple LVDC ports is significantly necessary.…”

Owing to the diverse connection configurations of dual active bridge converters, a multiplicity of low-voltage DC port structures are anticipated to emerge in the independent DC bus structure multiport power electronic transformer (IDBS-MPET). An inadequate low-voltage DC port structure exacerbates the power imbalance in IDBS-MPET, presenting a risk of overmodulation even when transmitting relatively low levels of power. To overcome this limitation, a design scheme of IDBS-MPET topology based on the maximum power transmission capability of the low-voltage DC ports is proposed in this paper. Three topology design rules are derived from the maximum power transmission capability results of more than 80 typical IDBS-MPET topologies. The symmetrical triple cross-phase connection structure, the symmetrical double cross-phase connection structure and the single-phase connection structure are sequentially identified as the three most optimal structures of low-voltage DC ports. By employing the proposed design methodology, each low-voltage DC port achieves its maximum power transfer capability relative to other configurations. The effectiveness of the proposed design scheme is validated by an optimal designed IDBS-MPET topology with six low-voltage DC ports.
