Voltage Distortion Minimization in Cascaded H-Bridge Inverters
2019Multilevel 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 ...

Cascaded H-bridge Multilevel Inverters -A Reexamination
2007 IEEE Vehicle Power and Propulsion Conference, 2007Multilevel 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

Cascaded H-bridge control for PV application
2015 17th European Conference on Power Electronics and Applications (EPE'15 ECCE-Europe), 2015In this paper, application of a cascaded H-bridge (CHB) converter to connect strings of solar panels to a single-phase medium voltage AC grid is discussed. With solar insolation levels differing from one string to another, it is challenging to control a CHB converter in order to minimize the variations in the dc link voltages of each of the converter ...

A new cascaded multilevel H-bridge drive
IEEE Transactions on Power Electronics, 2002In 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 ...

Cascaded H-Bridge Multilevel Active Compensator
2006 IEEE International Power Electronics Congress, 2006A compensator for harmonics and reactive power is presented based on a Cascaded H-bridge multilevel three phase inverter. Compensating current is calculated by using concepts of instantaneous power in a very simple way. The current regulation is carried out in a synchronous reference frame and the multilevel inverter is commanded by a sinusoidal ...
