In this paper. a novel HTS CIM was studied based on the minimization of the torque ripple and the perpendicular magnetic field component to the tape surface. The results shows that the performance of HTS materials is still not fully developed. but also needs further optimization. Based on the initial …

In this letter. a simple ESO based DC-link voltage control strategy was proposed for three-phase AC DC converter. With the proposed control strategy. additional sensors for improving system dynamic response under disturbance was avoided. which was suitable for “plug and play“ for expanding the UPS modules and microgrid. The proposed …

We have established a lower bound on load capacitance which can guarantee network stability without pre-determining the network topology. Our bound provides a theoretical foundation for ad hoc microgrids with modular source and load units. The development process for these microgrids is 1) Define acceptable voltage levels across all units …

Solid particles impair the performance of the photovoltaic (PV) modules. This results in power losses which lower the efficiency of the system as well as the increases of temperature which additionally decreases the performance and lifetime. The deposited dust chemical composition. concentration and formation of a dust layer on the …
