The paper describes blended learning approach to teaching uncontrolled rectifiers. It is based on “Learning by Doing” paradigm supported by several learning tools: electronic course materials, interactive simulation, laboratory plants and real experiments accessed by Web Publishing Tools under LabVIEW. Studying and experimenting access is(More)
In this paper modeling, computer simulation, design approach and analysis for matrix converters input filter are presented. This filter design procedure makes possible to achieve the required EMI attenuation, the desired power factor and a high efficiency with a significant filter size reduction and minimum cost components. Also it is presented analyses of(More)
This paper proposes a new control technique for single-phase boost power-factor-correction rectifiers. The proposed circuit improves the dynamic response of the converter to load steps without the need of a high crossover frequency of the voltage loop. So a low distortion of the input current is easily achieved. A 200W power-factor correction rectifier with(More)
