Double H-bridged and single H-bridged diboryl radicals

Structural Chemistry, 1990
The structures of B2H5·, B2H5CO·, and B2H5N2· radicals are investigated using the 6–31G* basis set. Both double H-bridged and single H-bridged isomers are found to be local minima on the potential energy surface. The effects of electron correlation are taken into account using single point MP4/6–31G* calculations and, for the diboryl radicals, complete

Multi-pulse Rectifiers Feeding H-bridge Inverter

Electric Power Components and Systems, 2014
AbstractThis article presents a comparative analysis of 12-, 18-, 24-, and 36-pulse rectifier topologies supplying 3-phase three-level H-bridge inverters as active loads. The analysis comprises the total harmonic distortion data of the inverter and grid currents and voltages, including inter-modulation harmonics.

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 ...

Cascaded H-Bridge Inverter based PV-STATCOM

2018 International Conference on Smart Electric Drives and Power System (ICSEDPS), 2018
The environmental effect and need of energy have been increasing rapidly, due to this demand for renewable resources increased. One of the renewable resources Solar Photovoltaic (PV) energy is presently most popular in the environment. An inverter is a necessary part of grid-connected PV systems.This paper presents a new approach of largescale ...

Control of H-bridge based multilevel converters

Industrial Electronics, 2002. ISIE 2002. Proceedings of the 2002 IEEE International Symposium on, 2002
Multilevel converters are suitable for high voltage and high power applications. Among them H-bridge ones have encountered good success due to their simpler layout and the reduced number of components over the counterparts. H-bridge multilevel converters used as active rectifiers represent an attractive solution in traction systems due to the ...

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.
