CASCADED MULTILEVEL INVERTER WITH FUZZY BASED D-STACTOM FOR REACTIVE POWER & HARMONICS COMPENSATION
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 4, Issue 11
Abstract
This paper presents an investigation of five-Level Cascaded H-bridge (CHB) inverter as Active Power Filter in Power System (PS) for compensation of reactive power and harmonics. The advantages of CHB inverter are low harmonic distortion, reduced number of switches and suppression of switching losses. The D-STACTOM helps to improve the power factor and eliminate the Total Harmonics Distortion (THD) drawn from a Non-Liner Diode Rectifier Load (NLDRL). The D-Q reference frame theory is used to generate them reference compensating currents for D-STACTOM while Fuzzy controller(FC) is used for capacitor dc voltage regulation. A CHB Inverter is considered for shunt compensation of a 11 kV distribution system. Finally a level shifted PWM (LSPWM) & Phase shifted PWM (PSPWM) technique adopted to investigate the performance of CHB Inverter. The results are obtained through Mat lab/ Simulink.
