There are many types of control method for shunt active power filter (SAPF) investigated up until now. The authors describe complex methods of determining active filter reference currents or powers. This paper is dedicated to a simple, but universally used control algorithm based on the load equivalent conductance approach. This method allows for non-active current compensation, energy buffering, and energy redistribution among loads under compensation. It is also useful for voltage-source as current-source inverter based active filters, and for DC system as well as for AC single or three-phase filters.

Zadaniem energoelektronicznego filtru aktywnego jest kompensacja prądu nieaktywnego w gałęzi źródła zasilania. Znanych jest wiele metod pozyskiwania informacji niezbędnych do skompensowania tego prądu. Często są to wyrafinowane metody, bardzo złożone zarówno pod względem pojęciowym, jak i obliczeniowym. W niniejszym artykule przedstawiono nieskomplikowaną, lecz wydajną i wielofunkcyjną metodę uzyskiwania wzorca składowej czynnej prądu obciążenia. Jest ona oparta na pojęciu konduktancji zastępczej obciążenia. Umożliwia nie tylko kompensację prądu nieaktywnego, ale również sterowanie przepływem energii czynnej, w tym jej rekuperację i redystrybucję do kompensowanych obciążeń. Opisana metoda może być stosowana w obwodach jedno- i wielofazowych, a także w obwodach zasilanych sygnałem stałym. Może też zostać użyta wobec filtru aktywnego opartego i na falowniku napięcia, i na falowniku prądu.
