Abstract :
This paper presents a shunt active power filter based on the concept of open-end winding (OEW) transformer for three-phase three-wire systems. The proposed configuration is constituted of two converters, with three legs in each one, series-connected throughout a three-phase OEW transformer. Model, pulsewidth modulation (PWM) strategy, and control scheme are presented as well. The main advantage of the proposed system lies on the multilevel waveform generation, which allows reduction of either harmonic distortions or switching losses. This proposed topology is suitable for medium-voltage distribution systems. Simulation and experimental results validate the theoretical study.
