| dc.description.abstract | This paper proposes the lifetime extension of DC-link capacitors in three-level inverters based on the neutral-point (NP) current. High-capacity inverters require large-size capacitors to maintain robust DC-link voltage. The proposed method suppresses the ripple current of the DC-link capacitors by replacing the switching states, which are optimized for two specific modulation index regions in the linear modulation range. The reliability of the DC-link capacitors is analyzed using a capacitor lifetime model. The validation of the proposed method is supported by simulation and experimental results across various conditions. | - |
