In this paper, an optimized space-vector modulation (SVM) to reduce DC-link ripple current in three-level inverters is presented. Various 

types of capacitors can be utilized to balance the voltage in the DC-link of voltage source inverters. Electrolytic capacitors are widely 

used owing to their large capacitance per volume. However, electrolytic capacitors have a short lifespan because the allowable ripple 

current is low. A conventional SVM that is focused on improving harmonic characteristics. Therefore, it cannot balance the DC-link ripple

current properly because using some voltage vectors increases the DC-link ripple current. To overcome this limitation and extend the 

lifespan of the capacitors, an optimized SVM is proposed to reduce the DC-link ripple current. The proposed modulation scheme 

synthesizes the reference voltage by choosing voltage vectors that cause smaller increases in the DC-link ripple current, avoiding those

that cause larger increases. The effectiveness of the proposed optimized SVM is verified by simulations and experimental results.
