Shunt Active Power Filters Based On Diode Clamped Multilevel Inverter and Hysteresis Band Current Controller

EM?N TACER, Akram Qashou, Nezihe yildiran


This work focused to design and implementing the three phase shunt Active Power Filter (SAPF) based in instantaneous reactive power theory which we used to generate the reference current and measure the power and reactive power and power factor and using Hysteresis Band Current Controller to obtain the gating signals for 11-steps diode clamped multilevel inverter (DCMLI). The proposed system represent two inverter Shunt Active filters  is less total  harmonic distortion (THD) and reduced semiconductor  ratings compared with conventional inverter. The current drawn by the non- linear load and improve the source side power factor by compensate the reactive power. Also, the shunt Active Power Filter (SAPF) system response has been tested under steady state and transient conditions for real time current compensation harmonics. A study of its performance through simulation results will be investigated through MATLAB Simulink.

Keywords: Shunt Active power filter (SHAPF), diode clamped Multilevel Inverter (DCMLI), Hysteresis band controller.
