This study proposes a multitasking three-phase four (3P4W) wire solar photovoltaic (SPV) system using a modified lattice wave digital filter (M-LWDF)-based control technique. For effective utilisation of SPV array, an incremental conductance-based maximum power point tracking approach is used to obtain the peak power. However, M-LWDF-based control technique is used to control the grid tied 4-leg voltage source converter. The proposed control technique with reduced computational burden is an analytical tool for extracting the harmonics free fundamental component of load current and the mitigation of load neutral current. The M-LWDF-based control technique is implemented under various working modes at non-linear loads.
