فاقد چكيده فارسي

This article presents a single phase eleven-level inverter based on switched-capacitor (SC) technique, which can realize eleven-level output with single dc source. In addition, it can produce more levels by a cascaded structure. Without utilizing the auxiliary balance circuits, or complicated control strategies, the two capacitors in series connection can innately keep voltage balance at 0.5Vdc, and the floating capacitor can obtain self-balance at Vdc. The merits of the eleven-level switched-capacitor inverter (11-LSCI) on reduced components, capacitors self-balance capability, enhance output amplitude and inductive-load ability are also illustrated through the comparison against other proposed multilevel inverters (MLIs). It should be noted that less semiconductor components in the proposed topology reduce switching and conduction losses. Therefore, increases efficiency. Finally, the simulation results are brought to verify the effectiveness and performance of the presented inverter.
