Abstract :
This paper proposes an innovative control strategy for a three phase four wires power conditioner with UPS function. The topology consists of two shunt converters with a common dc section and an inductor between them on the AC side. This inductor decouples load from mains and allows a controlled load voltage even in presence of mains voltage noise. The power conditioner at the line side acts as an ideal resistive load. The proposed switching strategy is based on sliding mode control, it is characterised by high dynamic performances with a significant simplification of control structure. Simulation results are reported.
