LCL filter optimal parameter selection method for grid-connected inverter
Dianzi Jishu Yingyong, 2018 The existing filter design methods only consider the filter characteristics. The influence of the change of the ratio of the two inductor parameters on the filter performance is not analyzed, and the limit about the switching frequency of the filter ...

Crossover from Kramers to phase-diffusion switching in hysteretic DC-SQUIDs [PDF]
, 2005 We have measured and propose a model for switching rates in hysteretic DC-SQUID in the regime where phase diffusion processes start to occur. We show that the switching rates in this regime are smaller than the rates given by Kramers' formula due to ...

Y-branch switch frequency bisection
Electronics Letters, 2006 Frequency bisection by a coupling of two Y-branch switches is demonstrated. One Y-branch switch serves as a trigger controlling the in-plane field at the second Y-branch switch, which is in turn feedback coupled into a bistable regime. At the trigger Y-branch switch spike-like pulses are amplified or attenuated.

FEBS Letters, EarlyView.Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

High Power High Frequency Soft Switching Converter Using Serial Connected Switches [PDF]
EPE Journal, 1999 This paper presents a chopper topology suitable for high voltage, with a switch made of serial connected power devices. Serial connection of power components encounters two major problems in hard switching : voltage unbalance and overcurrents at turn on due to parasitic capacitances to ground.
