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 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 ...

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 ...

A Decentralized Controller Architecture for a Cascaded H-Bridge Multilevel Converter
IEEE Transactions on Industrial Electronics, 2014Despite its inherently modular hardware structure, the control system of most cascaded H-bridge converters is usually highly centralized and relies on a high-bandwidth intraconverter communication system to transmit time critical control signals to the module controllers.
