Abstract
This paper proposes a new single-phase hybrid-modular multi-level inverter (H-MMI) topology. The proposed H-MMI can ensure fault-tolerance under different faulty scenarios. The H-MMI architecture utilizes a series connection of DC sources and power switches to generate multiple voltage levels, but this arrangement also increases the system’s vulnerability to failures. To address this challenge, a fault-tolerant technique is proposed for the H-MMI inverter, ensuring reliable operation even in the presence of component failures. Furthermore, the proposed control method can be utilized to compensate any voltage drop of the dc-link caused by the aging of the input capacitors. The eleven-level form of the proposed H-MMI is simulated in PLECS program. The results show that the inverter output current effectively tracks the reference current, maintaining stable operation even during faulty scenarios.
