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 ...

Low-Capacitance Cascaded H-Bridge Multilevel StatCom

IEEE Transactions on Power Electronics, 2017
This paper introduces a cascaded H-bridge multilevel converter (CHB-MC)-based StatCom system that is able to operate with extremely low dc capacitance values. The theoretical limit is calculated for the maximum capacitor voltage ripple, and hence minimum dc capacitance values that can be used in the converter. The proposed low-capacitance StatCom ( LC -

Flying capacitor four-level H-Bridge converter

2014 Power and Energy Conference at Illinois (PECI), 2014
This paper proposes single-phase and three-phase four-level converters with a flying-capacitor leg and a conventional two-level leg per phase. The main advantages of the proposed converter are as following: (1) the same blocking voltage for all switches employed, (2) no capacitor midpoint connection needed (i.e., no low frequency current circulating in

Hybrid thirteen level cascaded H-bridge inverter

Electrical Engineering, 2015
The paper presents an analysis of a hybrid 13-level inverter, which consists of three cascaded H-bridges per phase. Each H-bridge produces 5-level voltages. The proposed approach can be extended to any desired number of levels. Extensive simulation results of the proposed inverter are presented.

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

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 ...
