Cascaded H-Bridge MLI and Three-Phase Cascaded VSI Topologies for Grid-Connected PV Systems with Distributed MPPT

International Journal of Photoenergy, 2019
Cascaded multilevel inverter topologies have received a great deal of attention for grid-connected PV systems. In this paper, three-cascaded multilevel inverter configurations are proposed for grid-connected PV applications.

Enriched Environment Enhances Motor Function in Mice With Cerebral Infarction by Promoting mTOR‐Dependent Autophagy in the Contralateral Dentate Nucleus

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Although environmental enrichment (EE) promotes post‐stroke motor recovery, the mechanisms underlying its regulation of cerebellar dentate nucleus (DN) plasticity remain unclear; this study therefore investigated how EE coordinates autophagy, mitochondrial homeostasis, and synaptic remodeling in the contralateral DN to facilitate functional ...

A Comprehensive Multistage Average Controller for Trajectory Tracking in Solar‐Powered Mobile Robots: Analysis of Actuator‐Driver and Power Stage Integration

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This work addresses the challenge of bidirectional trajectory tracking in solar‐powered wheeled mobile robots (WMRs), considering the mechanical structure, actuator‐driver, and power stage subsystems. Notably, this is the first study to explicitly model and control the actuator‐driver subsystem within this context. The proposed solution relies

Modelling Suicide‐Related Communication Dynamics: A Socio‐Cybernetic Framework for Governance

Systems Research and Behavioral Science, EarlyView.
ABSTRACT Suicide‐related phenomena (SPS) are often approached through individual‐level risk factors or moral framings, yet their population‐level dynamics depend critically on how ‘suicide’ becomes observable, circulates and is governed across functionally differentiated systems.

Ripple Effects: Social Turmoil Following Infant Kidnapping Attempts in Wild Geladas

Ethology, Volume 132, Issue 7, Page 485-497, July 2026.
Graphical abstract illustrating the social consequences of infant kidnapping in wild geladas (Theropithecus gelada). The study monitors a 28‐day period divided into a 14‐day pre‐kidnapping phase and a 14‐day post‐kidnapping phase. ABSTRACT Infant kidnapping is an extreme social disruption reported in some primate species, yet its consequences on social

Simulation of a 41-level inverter built by cascading two symmetric cascaded multilevel inverter [PDF]

2016 7th IEEE Control and System Graduate Research Colloquium (ICSGRC), 2016
The main disadvantage for cascaded multilevel inverter is the high number of switching device it needs in an installation. To reduce total harmonics distortion (THD) of the output waveform, the number of output voltage level has to be increased, hence the higher number of switching devices.

Integral Sliding Mode Controller for Modular Multilevel Inverter‐Based PMSM Drives

Engineering Reports, Volume 8, Issue 6, June 2026.
The primary contribution of this work is the development of an integral sliding mode controller (ISMC) designed for motor speed and current regulation, optimized to enhance control performance with the unique MMLI structure. The proposed MMLI architecture offers a reduced number of switching components and passive elements, thereby minimizing system ...
