Abstract
Conventionally, a six-step inverter used in Active Power Filter (APF) to mitigate the harmonics in power system because of its simplicity and easy to control. However, six-step inverter only operates in low voltage rating for APF and additional transformer is essential to operate in high voltage rating of APF. There are three types of Multilevel Inverter (MLI) namely Cascaded H-Bridge, Neutral Point Diode Clamped (NPC) and Flying Capacitor (FC). Among the types of Multilevel Inverter (MLI), only the Cascaded H-Bridge (CHB MLI) can be used to replace the conventional six-step inverter due to its capability to work in high voltage rating, less used power device and easy to control. This paper evaluates a three-phase three-wire shunt APF based on six-step conventional inverter and Nine Level CHB MLI using Indirect Current Control (ICC) schemes. MATLAB/Simulink tools are used to model and simulate both of algorithms, consisting of three main parts namely harmonic extraction algorithm, DC link algorithm and switching algorithm. In MATLAB/Simulink, the model was created and validated the Total Harmonic Distortion (THD) line current with different frequency modulation (mf) values. According to the findings, the increasing of frequency modulation will produce a good result of THD line current. The THD line current produced by both algorithms is less than 5%, which is the permitted value as stated in IEEE 519.
