Cascaded H-bridge control for PV application

2015 17th European Conference on Power Electronics and Applications (EPE'15 ECCE-Europe), 2015
In 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, 2006
A 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, 2014
Despite 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.

Quasi Cascaded H-Bridge Five-Level Boost Inverter

IEEE Transactions on Industrial Electronics, 2017
Latterly, multilevel inverters have become more attractive for researchers due to low total harmonic distortion in the output voltage and low electromagnetic interference. This paper proposes a novel single-stage quasi-cascaded H-bridge five-level boost inverter (qCHB-FLBI).
