Summary: | This paper presents a modern solution based on power electronics, recommended to solve the problems posed by harmonic pollution of the electrical network. This pollution is generated mainly by nonlinear loads such as rectifiers with diodes and thyristors, recognized as the principal source of harmonic currents injection. As such, a curative solution was provided by a new three-phase parallel active filter based on the multilevel Vienna converter. The novel task assigned to the Vienna converter is to compensate the reactive power and to eliminate the harmonic currents caused by the nonlinear polluting loads. A simple and effective control approach has been developed guaranteeing sinusoidal shape source currents and unity power factor of the electrical network. In addition, the multilevel Vienna converter-based parallel active filter operates with convincing performances identified through the admitted DC output voltage undulations and the balance between the two partial outputs voltages. Satisfactory results have been obtained when the proposed algorithm has been subjected to simulation using the MATLAB/Simulink software and confirmed in real-time implementation via a dSPACE 1104 card. |
