Summary In this paper, a photovoltaic (PV) array tied modified three‐port interleaved flyback converter (MTPIFC) is proposed to power shunt active power filter (SHAPF). The MTPIFC is intended to feed a SHAPF from a PV power source to overcome the power quality issues associated with the interconnection of nonlinear loads with the low‐power distribution network. The three‐phase six‐level cascaded multi‐level inverter operated as a SHAPF reduces the current harmonics and the number of active and passive components compared to widely used MLI. This study also presents a DQ current control method with a modified phase‐locked loop to generate the required reference signal for the PV‐SHAPF. Extensive recreation and test contemplates are done to confirm the capacity of the suggested PV‐SHAPF.
