“…Using the multicarrier SPWM strategy, the triangular carrier signal was compared to the sinusoidal reference signal and the received pulses. Therefore, the control signal for the power semiconductor switches was used to obtain the suitable multilevel PWM waveform [5,9]. For better understanding, the MATLAB/Simulink block of the five-level CCS-MLI topology is shown in Fig.…”

“…The obligatory need for a high-quality power supply has recently brought the multilevel inverter into the limelight. Basically, MLIs can be classified into three types: neutral point clamped (NPC), flying capacitor (FC), and cascaded H-bridge multilevel (CHB) MLI [5]. Among these traditional topologies, the CHB is the most popular because of its modularity and easy extension for higher voltage requirements [6].…”

Multilevel inverters (MLIs) are very popular in renewable energy applications and other DC to AC conversion systems due to their reliability, reduced voltage stress, low total harmonic distortion (THD), reduced filter size, low electromagnetic interference, etc. Consequently, the photovoltaic (PV) generation systems, mainly installed in remote areas, require highly reliable systems. The high failure rate of sources and power semiconductor devices results in very low reliability for inverters used in PV generation systems. The aim of this study is to develop a five-level MLI topology with fault-tolerant (FT) characteristics. Therefore, a highly resilient fault-tolerance topology, based on a cross-connected source-based MLIs (CCS-MLI) structure, is proposed in this paper. The developed CCS-MLI topology can tolerate open switch faults in any single switch failure. The proposed system and results developed in a MATLAB/Simulink environment are discussed under normal and faulty states. The simulation results are validated experimentally. Finally, the quantitative and qualitative superiority of the proposed CCS-MLI is demonstrated through the comparative analysis of other recent topologies.
