Modelling and performance evaluation of diode‐assisted impedance source networks
IET Power Electronics, 2021 This paper deals with a family of two‐ and three‐windings coupled inductor‐based impedance source networks. They have been basically derived from the successful quasi‐Y‐source network (q‐YSN) by replacing one of its capacitors with a diode with different

Fault ride‐through strategy for hybrid HVDC with cascaded multi‐infeed MMC inverters
Electronics Letters, 2021 The hybrid HVDC with cascaded multi‐infeed MMC inverters suffers from the fragile characteristic of its MMC inverters and is easy to be over current and over voltage.

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
FEBS Letters, EarlyView.The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only
