The paper describes the active power filter structure, control algorithms and methods for filter current regulation. Firstly, there is described the structure of parallel active filter power part, their resonant DC - link and structure of active filter general conception. Then there is described the control algorithms and methods for filter current regulation. The paper is mainly orientated to control...
Growing numbers of consumers distort AC networks with harmonics. Therefore suppression of the network pollution should be considered. This problem can be solved by using "network-friendly" converters. In this article some consumers are presented that pollute the single-phase AC networks with harmonics. Therefore the network voltage waveform will be distorted. In our study we examine the...
The paper proposes a solution for improving the power quality in a transportation system. The experimental determinations revealed a high level of harmonics and a high consumption of reactive power. The simulation using MATLAB/Simulink software was conceived and validated. A solution using passive filters is proposed and analyzed.
