This conference paper shows and demonstrates how modern technologies (such as WDM – Wavelength Division Multiplex) were introduced to students of Optical Networks lectured at Brno University of Technology, Faculty of Electrical Engineering and Communication, Dept. of Telecommunications.

This contribution summarizes some of the major trends, as well as real opportunities for the application of system fault diagnosis and reconfiguration control structures in automatic control systems. There are referenced ongoing concepts for residual generation, described design approaches in virtual reconfiguration…

The article presents a mathematical model of thyristor inverter including a series-parallel resonant circuit with theaid of state variable method. Maple procedures are used to compute current and voltage waveforms in the inverter.

This article deals with a description of methods of an experimental analysis concerning the actual condition of windings and magnetic circuit of the autotransformer, which is required in power transmission companies all over the world.

Utilization and construction of renewable energy sources require complexity of whole system. It is considered touse a set of devices that are necessary for energy conversion, accumulation, preparation and its distribution into electrical power supply network. The way of realization…
