In recent years voltage and current harmonics are become serious problem in transmission and distribution system. To eliminate these voltage and current harmonics and to achieve clean grids, AAF are been used. The existing AAF technology requires a higher dc link voltage to achieve the THD requirement therefore this paper presents an Advanced Active Filter AAF for IGBT and LCL network in order to maintain voltage balance among dc link. This method is well capable of balancing charging and discharging of dc link voltage without increasing circuit complexity. This modulation technique is very effective in terms of voltage balancing as well as for maintaining voltage output THD at low level. The proposed system is implemented in Simulink platform of MATLAB software and performance shows its effectiveness over conventional IGBT used for inverter
