This paper presents a high-voltage CMOS PV mini-module fabricated using a one-step LSR process. The proposed PV mini-module features adjustable (0.5 to 12.5V) open-circuit voltage and µA-scale short-circuit current in a small form factor with a specific open-circuit voltage <.Voc>. of 3.13 V mm2. Only 25 on-chip PV cells were …

While many transportation and city planners. researchers. students. practitioners. and political leaders are familiar with the technical nature and promise of vehicle automation. consensus is not yet often seen on the impact that will result. or the policies and actions that those responsible for transportation systems should take. The End …

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 …
