Improvement of Post-Fault Performance of a Cascaded H-bridge Multilevel Inverter [PDF]

IEEE Transactions on Industrial Electronics, 2017
This paper is focused on improving the post-fault performance of cascaded H-bridge multilevel inverters by decreasing the common-mode voltage. First, an algorithm is proposed to determine the optimal post-fault state among all possible states, which have the same maximum available voltage.

Model Predictive Control of Multilevel Cascaded H-Bridge Inverters

IEEE Transactions on Industrial Electronics, 2010
This paper presents a model predictive current control algorithm that is suitable for multilevel converters and its application to a three-phase cascaded H-bridge inverter. This control method uses a discrete-time model of the system to predict the future value of the current for all voltage vectors, and selects the vector which minimizes a cost ...
