Improving the Efficiency of the Shunt Active Power Filter Acting with the Use of the Hysteresis Current Control Technique

Calculation of the reference waveform for compensating current generated by shunt active power filter (ShAPF) can be carried out using various methods. In this article, calculation is performed indirectly on basis tracking and processing ShAPF DC-link capacitor voltage. At same time, energy stored in used to generate current. Therefore, operation during compensation, i.e., changes it voltage its terminals, characteristic crucial method considered. Once determined, ways, but always capacitor. The module uses transistor switches realize required During their operation, losses occur that divided into either switching or conduction. article shows that, case indirect control hysteresis technique used, possible reduce operating frequency load Thanks this, these elements extend lifetime.
