This paper presents a case study of the impacts of 25kV traction power system on railway signalling system using copper cables as communication links. Several forms of interferences including electromagnetic including and conductive have been investigated and remedial measures implemented, with satisfactory results. Key-Words : Traction Power System, electromagnetic interference, railway signal...

The electrified railway system has been rapidly rolled out in many countries and regions the past decades, along with transportation decarbonization agenda. latest development power electronics electrical systems increased risks of electromagnetic interference (EMI) intentional EMI (IEMI) emissions, introducing new challenges to radio communications network. It is vital have a robust reliable c...

In wireless communication, interference between two radio systems may occur when they operate at close frequency bands, sharing the same environment at the same time. Such systems coexist if both of them perform correctly in the presence of the other. To ensure their coexistence, Electromagnetic Compatibility (EMC) is used to specify rules within standardization bodies. According to current EMC...

Accurate and comprehensive methods for the assessment of radiated electromagnetic emissions in modern electric transportation systems are a necessity. The characteristics susceptibility victim signaling communication radio services, operating within outside right-of-way, require an update measurement integrating or replacing swept frequency technique with time domain approaches. Applicable stan...

Fast switching techniques at high frequencies are employed for quick charging and energy conversion in electric vehicle (EV) power converters. Electromagnetic interference (EMI) noise is produced due to the fast-switching process, which may result malfunctioning degraded EV performance. In this work, a digital chaotic pulse width modulation (DCPWM) technique-based EMI mitigation process has bee...

Power Factor Correction (PFC) single-phase AC/DC converters are used in several power electronics applications as full wave control rectifiers improving quality and providing high standards of efficiency. Many papers dealing with the description or use such topologies have been published recent years; however, a review that describes organizes their specific details has not reported technical l...

Currently, healthcare practice generates data exchange and stores a huge amount of patient-specific information in electronic medical records (EMC) auxiliary databases. EMC used normal clinical practice, can now be for research. The various methods available obtaining during research projects, particular from integrated EMCs, have some unique capabilities. Of course, there are problems obstacle...

The European Green Deal’s goals are anticipated to be fulfilled in large part thanks the New Circular Economy Action Plan. It is believed that recycling materials will have a significant positive impact on environment, particularly terms of reducing greenhouse gas emissions and impacts this preventing climate change. Due complexity issue its practical ramifications, activity Waste Electrical El...
