This paper presents a novel approach to the multi pulse voltage converters (VC), especially voltage source inverters (VSI) and matrix converters (MC) based on several typical identical modules connected in parallel using coupled reactors. Such arrangements resulting in lower voltage distortions at extremely low switching frequency. The proposed arrangement was validated by simulation. Laboratory models...
The use of the coupled inductors in the multipulse matrix converter (MC) systems is described in the paper. The possible arrangements of the system are given together with the description of their operation parameters. Moreover, the influence of the system's topology on the output power quality is also presented. The invented converter structures evaluation results are given in the form of simulation...
A novel approach to the voltage source inverters (VSI) construction is presented in the paper. The invented inverter structures allow to operate several DC/AC converters in parallel resulting in lower voltage distortions at extremely low switching frequency. The research presented in the paper describes such a parallel operation of the VSI's which is possible thanks to the use of coupled inductors...
The article presents the results of the simulation research on the performance of Parallel Active Power Filters in the supply systems with various impedance and different topologies. What has been compared is a typical, the most commonly used Parallel Active Power Filter devices working on the basis of load current distortion and the device working on the basis of identification of network's voltage...
The natural environment is one of the factors of development activities location. The quality and availability of natural values influences bid prices of flats. The availability of ecosystems of special qualities such as rarity and uniqueness is not a desirable feature for potential buyers. This is due to conservation restrictions, and thus the limited possibilities to use the land for recreational...
Many renewable generation units (e.g. PVs, fuel cells, small wind turbines) require integrated DC-AC converters providing efficient high step-up power conversion. The recently proposed Z-source-type integrated buck-boost inverters characterize one stage energy processing and wide range of output voltage regulation. This paper presents the possibility of further extending Z-source-type inverters application...
ЯЗЫКОВАЯ И КУЛЬТУРНАЯ ЭКВИВАЛЕНЦИЯ В АНГЛИЙСКОМ И РУССКОМ ПЕРЕВОДАХ ВОЙНЫ ПОЛЬСКО-РУССКОЙ ПОД БЕЛО-КРАСНЫМ ФЛАГОМ ДОРОТЫ МАСЛОВСКОЙ Резюме Статья состоит из двух частей. В первой рассматривается проблема эквиваленции в переводе с исторической точки зрения. Авторы анализируют концепции полной, неполной и нулевой эквиваленций, принимая во внимание разные интерпретации: с древней по полисистемную теории...
