Fault Tolerant Reconfiguration System for Asymmetric Multilevel Converters Using Bi-Directional Power Switches
(IEEE, 2007)
Asymmetric multilevel converters can optimise the number of levels by using H bridges scaled in power of three. The shortcoming of this topology is that the H bridges are not interchangeable and then, under certain faulty ...
Fault-Tolerant Reconfiguration System for Asymmetric Multilevel Converters Using Bidirectional Power Switches
(IEEE, 2009)
Asymmetric multilevel converters can optimize the number of levels by using H-bridges scaled in the power of three. The shortcoming of this topology is that the H-bridges are not interchangeable, and then, under certain ...
23-Level Inverter for Electric Vehicles Using a Single Battery Pack and Series Active Filters
(IEEE, 2012)
Cascaded H-bridge (CHB) multilevel inverters have been conceived as an alternative to reduce total harmonic distortion (THD) in medium-voltage drives. The reduced THD makes them useful for electric vehicle (EV) applications, ...
Semi-conductors faults analysis in dual active bridge DC-DC converter
(Institution of Engineering and Technology, 2016-05)
Failures in power semi-conductors of a dual active bridge converter are characterised considering open-circuit faults in diodes and transistors. A detailed electrical waveforms analysis to identify the main symptoms of the ...
Development of a prototype for measuring plantar forces
(2009-12-01)
Studies on the distribution of plantar pressure between the sole of the foot and the ground were developed before the 19th century. Currently, the most often employed plantar pressure measurement systems are Pedar® and ...

Optimal asymmetry for cascaded multilevel converter with cross-connected half-bridges
(IEEE, 2015)
DC-AC conversion has been revolutionized by multi-level converters due to their high power quality, high modularity and high voltage operation with standard semiconductors. New multilevel topologies, voltage asymmetries ...
Phase-shifted Pulse Width Modulation with alternate zeros voltage for parallel connection of H-Bridges for High-Current Low-Voltage applications
(IEEE, 2019)
Phase-Shifted Modulation (PSM) applied to multilevel converters is an effective method for reducing the output THD. In this paper, a new unipolar PSM method is proposed to control internal circulating current of a high-current ...
