This paper presents a control method for reducing the distortion of the grid current at a grid-connected three-level neutral point
clamped (NPC) inverter. The grid current is distorted from the 5th and 7th harmonic components in the stationary frame current also
the 6th harmonic component in the synchronous frame current. In this paper, the 6th harmonic component on synchronous frame
is controlled by using all-pass filters (APFs) and proportional integral (PI) controllers for distortion of the grid side. When transformed
the 6th harmonic component is controlled, the 5th and 7th harmonic components are reduced. The validity of the proposed control
method is verified by simulation and experiment result using a 25kW three-level NPC inverter.
