Space Vector Modulation Techniques for Common-Mode Voltage Reduction in Three-Phase Transformerless Split-Source Inverters

Eletrônica de Potência, 2020
Photovoltaic (PV) systems with low input voltage usually employ an input boost converter and an output inverter. Regarding to this issue, the split-source inverter (SSI) provides a single power conversion stage which aggregates boost capability with low

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

Improved space‐vector modulation technique for common mode currents reduction

IET Power Electronics, 2013
Modified space‐vector modulations (MSVMs) that reduce the variations of common mode voltage (CMV) for decreasing common mode currents (CMCs) are a low cost interesting approach. Unfortunately the lack of full utilisation of the DC bus voltage is a severe drawback that can limit the exploitation of such modulation techniques, unless special ...

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.

Double-ring high-frequency common-mode switching oscillation current sensor for inverter-fed machine winding insulation monitoring

Global Energy Interconnection
Insulation failure significantly contributes to the unpredictable shutdown of power equipment. Compared to the partial discharge and high-frequency (HF) injection methods, the HF common-mode (CM) leakage current method offers a non-intrusive and highly ...

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

FEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Integrated common-mode and differential mode filter circuit for leakage current suppression in transformerless photovoltaic inverter systems / Xinjun Li, Zuhaina Zakaria and Muhamad Nabil Hidayat [PDF]

The transformerless photovoltaic inverter system will lead to a large leakage current between the photovoltaic inverter system and the ground, and the current reduction is mainly based on the optimization of circuit topology and control mode.
