A Fault-Tolerant Hybrid Cascaded H-Bridge Multilevel Inverter
IEEE Transactions on Power Electronics, 2020The cascaded H-bridge (CHB) inverter is one of the most attractive multilevel topologies for renewable energy applications. Due to the fact that CHB inverters employ a large number of components, they suffer from a higher probability of fault, which reduces the system reliability.

Control Method for Cascaded H-Bridge Multilevel Inverter Failures
2006 6th World Congress on Intelligent Control and Automation, 2006To increase the fault tolerance for cascaded H-bridge inverter, this paper presents a novel switch-based control method for operating the inverter when one or more switches are damaged. To control the inverter under faulty mode, only the faulty switches are disposed, the control signals for other switches in the faulty cell are modified according to ...

Analysis of new H-bridge based cascaded multilevel inverter
2016 10th International Conference on Intelligent Systems and Control (ISCO), 2016This paper deals with the design and analysis of new h-bridge based single and three phase cascaded multilevel inverter. It has two types of sources: symmetric and asymmetric source. In this topology asymmetric source is preferred because it provides large number of output voltage level with minimum number of switches.

Nine level cascaded H-bridge multilevel DC-link inverter
2011 International Conference on Emerging Trends in Electrical and Computer Technology, 2011This paper presents the nine level cascaded H-bridge multilevel inverter based on a multilevel DC link (MLDCL) and a bridge inverter to reduce the number of switches. An MLDCL can be a diode-clamped phase leg, a flying-capacitor phase leg, or cascaded half-bridge cells with each cell having its own DC source.

Novel cascaded H-bridge multilevel inverter with harmonics elimination
2013 International Conference on Green High Performance Computing (ICGHPC), 2013Multilevel inverter is one of the most recent and popular type of advances in power electronics. It synthesizes desired output voltage waveform from several dc sources used as input for the multilevel inverter. This paper presents the two techniques for improving the quality of the output voltage and efficiency. First, new novel topology for multilevel

Direct parallel operation of cascaded H-bridge multilevel inverters
2014 IEEE Applied Power Electronics Conference and Exposition - APEC 2014, 2014This paper proposes a method to parallel m digital controlled cascaded H-bridge (CHB) multilevel inverters directly with high bandwidth current sharing capabilities. The proposed method utilizes switch signal synchronization with dead time control to eliminate circulating current and adopts “piecewise” master-slave strategy to achieve equal current ...
