Design and implementation of two level shunt active power filter

Abstract

Power quality has become of utmost importance for the power systems owners, where, the power electronics systems are found nowadays in all systems, such as industrial applications, appliances and telecommunications. These systems, which use power switching devices, are source of harmonics and consequently deteriorate the quality of voltage and current in the grid utilities. For this reason, the passive filters can be used to eliminate some of these harmonics; however, they are not enough to improve the quality being required by standards. Therefore, shunt active power filter is proposed for study in this project. A two-level inverter configuration is proposed and control system will be designed and implemented to satisfy the required quality. MATLAB/Simulink with STM32f4 microcontroller will be employed to carry out the simulation and the experimental implementation of this project. The results will be analyzed and discussed.
