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 ...

Analysis of the Power Balance in the Cells of a Multilevel Cascaded H-Bridge Converter [PDF]
IEEE Transactions on Industrial Electronics, 2010 Multilevel cascaded H-Bridge converters (CHB) have been presented as a good solution for high power applications. In this way, several control and modulation techniques have been proposed for this power converter topology. In this paper the steady state power balance in the cells of the single phase two cell CHB is studied.

Lifetime-Based Discontinuous PWM for Cascaded H-Bridge Converters
IEEE AccessThe cascaded H-bridge (CHB) is an attractive converter topology because it can provide voltage and power scalability. However, due to the difference in electrical and thermal characteristics of power devices, the CHB can be composed of cells with unequal

A Cascaded H-Bridge With Integrated Boosting Circuit [PDF]
IEEE Transactions on Power Electronics, 2021 This letter proposes a multilevel inverter (MLI), which can be considered to be belonging to the cascaded H-bridge (CHB) family. In the proposed MLI, some of the H-bridges are connected to dc-sources, whereas most of the H-bridges are connected to only floating capacitors. A boosting circuit is integrated in the CHB, which permits charging the floating

Capacitor Voltage Shaper for Cascaded H-Bridge StatCom [PDF]
2018 IEEE 4th Southern Power Electronics Conference (SPEC), 2018 In this paper, an active shaping method of the capacitor voltage for a cascaded H-bridge (CHB) Iow-capacitance static synchronous compensator (LC-StatCom) is introduced. The traditional LC-StatCom is able to operate with large capacitor voltage ripples when it is operating with rated current.
