Soft-switching vector control for resonant snubber based inverters [PDF]
, 1997 This paper gives a new classification of soft-switching inverters according to the principle of operation. After discussing the soft-switching phenomena in hard-switching inverters, the concept of soft-switching vector (SSV) is introduced.

Research on efficiency optimisation of DAB converters considering current stress and soft‐switching
IET Power Electronics, 2022 To solve the problem of low efficiency of the dual active bridge (DAB) converter under the traditional single‐phase‐shift control, a natural soft‐switching current stress optimisation (NSS‐CSO) method is proposed by considering the current stress ...

Current-Controlled Negative Differential Resistance due to Joule Heating in TiO2
, 2011 We show that Joule heating causes current-controlled negative differential resistance (CC-NDR) in TiO2 by constructing an analytical model of the voltage-current V(I) characteristic based on polaronic transport for Ohm's Law and Newton's Law of Cooling ...

Self-consistent theory of molecular switching [PDF]
, 2008 We study the model of a molecular switch comprised of a molecule with a soft vibrational degree of freedom coupled to metallic leads. In the presence of strong electron-ion interaction, different charge states of the molecule correspond to substantially ...

A novel passive snubber soft-switching inverter
Dianzi Jishu Yingyong, 2018 An improved simple passive snubber inverter is proposed in order to solve the problem of complicated snubber circuit in the traditional soft-switching topology. Only a few passive components are used in the novel topology.

DC-DC High-Step-Up Quasi-Resonant Converter to Drive Acoustic Transmitters
Energies, 2022 This paper proposes a quasi-resonant step-up DC-DC converter to provide the DC-link voltage for piezoelectric transmitters (PZETs). The resonance not only provides a soft-switching condition for the converter switches, but also helps to decrease the ...

Influence of topography and Co domain walls on the magnetization reversal of the FeNi layer in FeNi/Al$\_2$O$\_3$/Co magnetic tunnel junctions [PDF]
, 2006 We have studied the magnetization reversal dynamics of FeNi/Al$\_2$O$\_3$/Co magnetic tunnel junctions deposited on step-bunched Si substrates using magneto-optical Kerr effect and time-resolved x-ray photoelectron emission microscopy combined with x-ray
