Power electronics remains an emerging technology. Two important factors in power electronics system are the switching speed of the devices and the total power loss in the system. If the switching speed can be increased ,improvements may be possible i.e. current ripples in an electrical machine or physical size of passive components may be reduced. Increased switching speed may cause additional losses in a power electronics system and increase the system cooling requirement. A common problem is that high-frequency phenomena like proximity eff ....etc

Microbend optical fiber sensor for high-spatial resolution measurement of strain distribution
Abstract:
A new optical fiber sensor system has been developed for measuring strain distribution. Microbend scattering process is used for the sensing of strain and high spatial resolution of 1m was achieved for both plastic and silica glass fiber. Keywords: Optical fiber sensor, strain distribution, microbending, plastic fiber, silica fiber, geo-textile,

Measurement and simulation of the electric field of high voltage
suspension insulators

Vassiliki T. Kontargyri, Ioannis F. Gonos*,y and Ioannis A. Stathopulos



INTRODUCTION
The insulator strings, which are used for the suspension of overhead transmission lines, constitute one of the most important parts of
the transmission lines as they used to give support to electrical conductors and shield them from ground or other conductors as well
as they provide the necessary mechanical suppo ....etc

Abstract—

This paper proposes a new soft-switched continuousconduction- mode (CCM) boost converter suitable for high-power applications such as power factor correction, hybrid electric vehicles, and fuel cell power conversion systems. The proposed converter achieves zero-voltage-switched (ZVS) turn-on of active switches in CCM and zero-current-switched turn-off of diodes leading to negligible reverse-recovery loss. The components’ voltage ratings and energy volumes of passive components of the proposed converter are greatly reduce ....etc
