Abstract:
The ever-increasing use of static converters such as diode and thyristor rectifiers in the industrial sector has a
negative influence on the degradation of the energy quality of electrical systems. These types of converters are
known as non-linear loads, characterized by their absorption of non-sinusoidal currents and their operation
under a degraded power factor. However, these converters are considered as the main source of injection of
harmonic currents. The purpose of this end-of-studies project is to improve the quality of the electrical energy
supplying a polluting load using a parallel active power filter based on the control of the p-q powers. This
method ensures good control of the DC/AC converter characterizing this filter. The effectiveness of the latter
has been successfully evaluated by the MATLAB/Simulink software where the results obtained are very
acceptable.
