Abstract A photovoltaic power generation solution with two seried photovoltaic arrays using neutral point clamp(NPC) three-level converter is proposed in this paper. Through zero sequence injection and neutral point voltage unbalance compensation, up and down DC voltage in neutral point clamp three-level converter can be adjusted independently, with no output AC voltage distortion caused by unbalanced neutral point voltage. Based on this principal, up and down solar panels’ independent MPPT control is realized and overall generated electric energy can be enhanced. Simulation and experiments are made to verify the goodness of proposed strategy.

Key words： Unbalance compensation neutral point clamp(NPC) three-level converter zero sequence voltage maximum power point tracking(MPPT)
