In recent times, multilevel inverters are used as a high priority in many sizeable industrial drive applications. However, the reliability and performance of multilevel inverters are affected by the failure of power electronic switches. In this paper, the failure of power electronic switches of multilevel inverters is identified with the help of a high-performance diagnostic system during the open switch and low condition. Experimental and simulation analysis was carried out on five levels cascaded h-bridge multilevel inverter, and its output voltage waveforms were synthesized at different switch fault cases and different modulation index parameter values. Salient frequency-domain features of the output voltage signal were extracted using a Fast Fourier Transform decomposition technique. The real-time work of the proposed fault diagnostic system was implemented through the LabVIEW software. The Offline Artificial neural network was trained using the MATLAB software, and the overall system parameters were transferred to the LabVIEW real-time system. With the proposed method, it is possible to identify the individual faulty switch of multilevel inverters successfully.

The use of non-linear capacitors improves the efficiency of turn-off snubbers for power electronic switches. The parameters for the determination of non-linear ferro-electric capacitors are discussed and a novel measuring method for the determination of the maximum operating voltage is suggested. The procedure to select ferro-electric capacitors is also discussed.

Abstract A novel generalized modular MLI topology blends the unique advantages associated with existing MLIs to enhance the output voltage level incorporating a comparatively lesser number of power electronic components for similar performances. The unique features of the proposed topology pertain to lower distortion as well as total standing voltage (TSV) and best level-switch ratio (LSR) amongst the state-of-art MLIs. Extensive simulations using MATLAB/Simulation platforms as well as experimental models of single-phase 7, 9, 11, 13, 15 level inverter validate the superiority of the proposed topology for pragmatic applications in uninterruptable power supplies, photovoltaic farms, wind farms, and fuel cells.
