Abstract: The “shoot-through” failure glossary define as the rush of current that occurs while both the devices are ON at the same time of a particular limb, which is one of the most perilous failure modes encountered in conventional inverter circuits of the active power filter (APF). Shoot-through results in reduced efficiency, typical ringing, increased temperature in power switches and higher Electromagnetic Interference (EMI). However, these conventional inverters suffer from “shootthrough”. To avert the “shoot-through”, dead time control could be added but it deteriorates the harmonic compensation level. A novel 3-phase 4-wire active power filter based on interleaved buck (IB) DC-to-AC converters with the instantaneous active and reactive current component (id-iq) control strategy is proposed here to mitigate the harmonics having PI and fuzzy logic (FLC) controllers. This interleaved buck (IB) DC-to-AC converter is augmented conventional phase leg configuration and is innately immune to “shoot-through” phenomenon, with the elimination of special protection features required in conventional inverter circuits. Here in this paper, a comparison has been made on the compensation capabilities of the 3-phase IB-APF with the PI and fuzzy logic controller (FLC) used by id-iq control strategy under different supply voltage condition.
