This paper proposes a control scheme based on an optimal triple phase-shift (TPS) for dual active bridge (DAB) DC–DC converters to achieve maximum efficiency. is performed by analyzing, quantifying, and minimizing the total power losses, including high-frequency transformer (HFT) primary secondary modules of DAB converter. To analyze converter, three operating zones were defined according low, ...

A local-magnetic-field-promoted photocatalytic overall water splitting system is developed for the Fe 3 O 4 /N-TiO 2 catalyst, and an unprecedented solar-to-hydrogen efficiency of 11.9 ± 0.5% achieved at 270 °C.

All organizations have structure. Researchers emphasized the importance of the organizational structure to achieve the goals and mission of an organization. Thus Performance assessment of organizing is essential for managers and decision makers to find weaknesses and eliminate them. Organizations are designed by different methods and process, based on same principles and theories. In this study...

Benchmarking is the major reason for widespread use of DEA models efficiency analysis. Determining closest targets DMUs, play a key role in benchmarking their best performance. In fact, these help develop certain performance enhancement plans that need fewer attempts made by DMUs. Therefore, this study proposes novel method based on network to determine most appropriate target every stage addit...

In this research, a pilot study and analysis of an innovative multi-channel photovoltaic/thermal (MCPV/T) system in a geographic location (35° 44' 35'' N, 50° 57' 25'' E) has been carried out. This system consists of integrating a photovoltaic panel and two PV/T heat-sink converters. The total electrical, exergy and energy efficiencies of the system at air flow rate of 0.005 kg/s and radiation ...
