Soft switched three-phase single switch boost-type rectifier

open access: yesProceedings of the Power Conversion Conference-Osaka 2002 (Cat. No.02TH8579), 2003
This paper proposes a soft-switched three-phase-single-switch-boost-rectifier circuit. The proposed circuit can perform zero-voltage-switching (ZVS) without any current and voltage sensors. For this circuit, both simulation and experiments have been performed.

Minimum Current Optimization of DBSRC Considering the Dead-Time Effect

open access: yesEnergies, 2022
In a dual-bridge series resonant converter (DBSRC) working at a high switching frequency, the dead-time effect is a serious issue. When the minimum current trajectory (MCT) method is applied, the inductor current cannot be minimized due to the dead-time ...

Soft-switching vector control for resonant snubber based inverters [PDF]

open access: yes, 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

open access: yesIET 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

open access: yes, 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 ...

DC-DC High-Step-Up Quasi-Resonant Converter to Drive Acoustic Transmitters

open access: yesEnergies, 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 ...
