this paper presents a detailed small-signal and transient analysis of a full bridge pwm dc-dc converter designed for high voltage, high power applications using an average model. the derived model is implemented in a typical system and used to produce the small-signal and transient characteristics of the converter. results obtained in the analysis of the high voltage and high power design examp...

This paper presents the “Cable Crawler”, a mobile teleoperated robot to inspect high voltage power lines. Its mechanism allows riding on the topmost ground cable of high voltage power lines and crossing a set of mast tips as well as smaller obstacles autonomously and thus is not limited to just move from mast to mast. The robot consists of an aluminium chassis, six propulsion units and two spac...

Nowadays the issue of vulnerability and protection of critical infrastructure is attracting a great deal of attention among scientific researchers. One of the most used approaches is that of complex networks. A critical infrastructure (e.g. a power grid) is represented as a graph in which nodes represent the main components of the network (e.g. power plants or trasmission substations) and edges...

BACKGROUND Extremely low-frequency magnetic fields are designated as possibly carcinogenic in humans, based on an epidemiologic association with childhood leukemia. Evidence for associations with adult cancers is weaker and inconsistent. METHODS We conducted a case-control study to investigate risks of adult cancers in relation to distance and extremely low-frequency magnetic fields from high...

The interline power flow controller (IPFC) is a concept of the FACTS controller for series compensation which can inject a voltage with controllable magnitude and phase angle among multi lines. This paper proposes a novel IPFC-Based Damping Neuro-control scheme using PSO for damping oscil‌la‌t‌i‌o‌ns in a power system to improve power system stability. The add‌i‌tion of a supplementary controll...
