A Fault-Tolerant Hybrid Cascaded H-Bridge Topology

2019 IEEE Energy Conversion Congress and Exposition (ECCE), 2019
This paper presents the fault-tolerant operation for a cascaded H-bridge (CHB) inverter. The added features ensure reliable and robust operation in the event of a fault. The proposed strategy uses an additional cross-coupled CHB (X-CHB) unit in companion with the existing CHB to support the output voltage and ensure continuity of operation in case of ...

Cascaded H-bridges for sub-module PV microinverter

2016 IEEE 25th International Symposium on Industrial Electronics (ISIE), 2016
In the recent years growing interest has been given to photovoltaic (PV) microinverters. Sub-modular optimization of PV panels where the junction-box of the panel is removed and each sub-modules is connected to an individual DC-DC converter realizing independent MPPT is one promising solution especially for systems subject to partial shading.

SVPWM Control of Cascaded H-Bridge Multilevel Inverters

Applied Mechanics and Materials, 2012
To solve the problem of computational complexity in H bridge cascaded multilevel inverter (HBCMI) control, this paper proposes a simple space vector pulse width modulation control algorithm. Base on the topology configuration of HBCMI, the output voltage is deduced, which is the difference value between two-level inverter group output voltage formed by

Management Algorithms for Cascaded H-Bridge Multilevel Inverters

2018 53rd International Universities Power Engineering Conference (UPEC), 2018
Multilevel inverters like the cascaded H-bridge topology provide multiple benefits compared to traditional B6-bridge inverters. Due to the modular structure of the inverter and the modulation techniques it is necessary to utilize management algorithms to achieve even energy distribution between all battery modules.

Partial Shading Abatement Through Cascaded H-Bridge Topology

2017 IEEE 44th Photovoltaic Specialist Conference (PVSC), 2017
Photovoltaic systems are susceptible to partial shading, which has a disproportional impact on their power production. This paper will examine a system architecture introduced by an earlier paper, and will verify it through a series of simulations. The novel architecture offers a solution to partial shading by utilizing inverters on a cell level.

A Modified Seven Level Cascaded H Bridge Inverter

2018 5th IEEE Uttar Pradesh Section International Conference on Electrical, Electronics and Computer Engineering (UPCON), 2018
Presently Multilevel inverters are extensively used for high-voltage applications and their execution is exceptionally better to that of regular two-level inverters due to minimized harmonic distortion, lower electromagnetic interference and larger DC link voltages.

Voltage Distortion Minimization in Cascaded H-Bridge Inverters

2019
Multilevel 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 ...

Indirect controller application on cascaded H-bridge rectifier

2011 2nd International Conference on Electric Power and Energy Conversion Systems (EPECS), 2011
This paper investigates the feasibility of indirect controller for a cascaded H-bridge rectifier. Using this method, the converter can connect directly to the medium voltage levels and eliminates the necessity to current sensors. In order to have a good approximation to the real current and to improve the converter performance, the dynamics of output ...
