Generic spice compatible model of current feedback in switch mode convertors
Electronics Letters, 1992 The mechanism of duty cycle generation in current mode (CM) and average current mode (ACM) PWM convertors is examined and found to be identical except for the functional relationship of the controlling parameters. This result is used to develop a SPICE compatible and topology independent generic current mode (GCM) model.

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

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

900 V GaN-based sine-wave inverters for three-phase industrial applications
The Journal of Engineering, 2019 GaN devices are gradually getting attention within the industry along with SiC as a potential wide bandgap device. At present, there are almost no high-voltage GaN devices with voltage >650 V, which makes an inverter design difficult for a three-phase ...

SPICE simulation of quasi-resonant zero-current-switching DC-DC convertors
Electronics Letters, 1990 A simple, topology-independent method is proposed for simulating the responses of open and closed-loop quasiresonant DC-DC convertors operating in the zero-current-switching mode (ZCS-QRC). The method hinges on the substitution of the resonant network and switch assembly, fundamental in the realisation of such systems, by an equivalent circuit which ...
