Shaft Voltage Suppression of Double-fed Generator for High Power Wind Turbine

Kongzhi Yu Xinxi Jishu, 2013
The mechanism and adverse effects of shaft voltage in double-fed generator generated by inverter is analyzed. As shaft voltage is part of common-mode voltage, a new LCL-filter of converter for suppression of common-mode voltage is proposed through ...

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Seamless Transfer Algorithm of AC Microgrid Inverter Compensating Load Current for Weak Grid

Energies, 2019
In this paper, we propose a voltage control technique for the seamless transfer algorithm of a microgrid inverter. When the microgrid inverter is switched from grid-connected mode to standalone operation mode, an output voltage transient may occur, and ...
