“…In the single-stage two-port DC-DC converters scenario, the growing number of sources and loads results in increased need of DC-DC converter sections to accommodate them into the system and to exchange the power. Effective utilization of renewable energy sources with improved reliability can be accomplished with integration of multiple energy sources and electrical energy storage stacks through an efficient single-stage multiport power electronics DC-DC converters [6][7][8]. Such converters help in reduction of overall energy conversion system size and corresponding controllers needed [9].…”

The advances in the field of power electronics have created a superior platform for interfacing clean renewable resources with the ever-growing energy storage technology. In this paper, a multidirectional power flow operation in the three-port isolated DC-DC converter (TBDC) topology has been demonstrated for interfacing different battery energy storage sections to increase the system reliability. Comparison of multiple battery integration with dual active bridge and TBDC has been presented. Converter analysis has been conducted using the Fourier series harmonic model and converter loss calculation is also presented. Power flow controller has been proposed for closed-loop control of the TBDC. The performance of the converter has been tested using MATLAB-based simulation and three modes of power flow control operation have been verified through scaled down laboratory experimental setup.

“…Active NPC (ANPC)-based five-level and Nlevel MLDAB with new modulation and capacitor voltage balancing method have been reported in [21]. For large-scale power transfer applications, multiple DABs are connected in parallel/series to reduce the current and voltage handling capability of each HB inverter [22][23][24][25]. The multi-input DAB converter has been considered in [22] for combining the output.…”

To cater unceasing supply to the modern AC and DC loads, renewable energy resources integrated hybrid DC/AC microgrid (HMG) are considered as a viable technological solution. In this study, a multiple parallel‐connected bidirectional converter (MPBC) topology has been proposed to enhance the solid‐state transformer (SST) power handling capability with flexible control of the HMG. To improve the high‐frequency AC‐link power quality and to control the power transfer through the SST in each dual active bridge a split‐step phase shift (SSPS) control technique has been used. A power management control strategy has also been proposed for efficient power transfer between the sources and loads of the HMG. The proposed MPBC‐based SST is suitable for interconnecting multiple utility feeders. Multiple redundant utility feeders ensure stiff bus voltages and omit the power supply reliability issues. The operation of the proposed MPBC‐SST converter system with corresponding control algorithm is verified through the simulation results in both grid feeding and grid fetching operating modes. Furthermore, experimental results are presented to validate the performance of the proposed MPBC‐SST converter along with its proposed controller strategy.
