The transformer percent differential protection is not reliable enough during external fault. if the differential restraint characteristic is the only one criteria providing security. The saturation of CTs during external faults could lead to cases of dangerously high differential restraint ratios crossing the characteristic into the operating region and causing …

To realize the wideband DPA above 3GHz. the frequency dependency compensating circuit and the λ ۴ inverter incorporating parasitic elements inside package were proposed. The feasibility of the approach was verified by measurement results. and it achieved 45.9- 50.2 % drain efficiency with -50 dBc ACLR over the 3.0- 3.6 …

In this paper. a novel MS-LMFM motor has been proposed and several varied geometric parameters have been optimized for maximum thrust force. Furthermore. a comparison between the proposed and existing motor has been carried out under fixed copper loss by FE method. Compared with the existing motor. it is confirmed …

The feasibility and performance of a battery charger for PHEV application using back to back (B2B) converter in a utility connected micro-grid has been investigated in this paper. A structure has been proposed involving three parts: an AC micro-grid. in which the load is fed from the DG source. a …

Motor drives is a widely used technology. offering many advantages. such as exceptional speed control and flexibility. Improvement of reliability and efficiency has become a great research interest. Toward this direction and considering the major recent developments in supercapacitor technology. the use of bidirectional energy recovery converters has been introduced …

The following is an example of one type of article we’d like to showcase. It’s a report based on a two-hour panel discussion on IoT in healthcare. held at the NIST offices in Gaithersburg. Maryland on 30 August 2017. The panel was part of a one-day workshop on IoT sensors …

Power Generation Technologies. Third Edition is a comprehensive guide on the full spectrum of currently available power generation options. from traditional fossil fuels and better established alternatives. such as wind and solar power. to emerging renewables. such as biomass and geothermal energy. New to this edition are expanded chapters on …

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 &lt.Voc&gt. of 3.13 V mm2. Only 25 on-chip PV cells were …

In this paper. an IACA has been proposed. and the pheromones of the path are adaptively adjusted to avoid the local optimum. Simulation results based on MATLAB verified the feasibility of the proposed algorithm. The IACA has good robustness. and can be used in an AFTC system. which varies its …

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 …
