Cascaded H-bridge Multilevel Inverters -A Reexamination

2007 IEEE Vehicle Power and Propulsion Conference, 2007
Multilevel converters have gained popularity in high-power applications due to their low switch voltage stress and modularity. Cascaded H-bridge converters are a promising breed of multilevel converters which generally require several independent dc sources. Recently, existence of a redundant switching state has been utilized to replace the independent

Voltage Distortion Minimization in Cascaded H-Bridge Inverters

2019
Multilevel inverters based on the series connection of H-bridges are the most modular multilevel inverter family. The use of a large number of these devices connected in series, controlled by modulation based on the fundamental frequency, allows to obtain an output voltage of the inverter with low harmonic distortion and low losses in the inverter ...

A new cascaded multilevel H-bridge drive

IEEE Transactions on Power Electronics, 2002
In this paper, a general structure for cascaded power converters is presented in which any number of H-bridge cells having any number of voltage levels are series connected to form an inverter phase leg. Equations are introduced for determining an optimal voltage ratio of DC voltages for the H-bridge cells which will maximize the number of voltage ...
