Bidirectional soft-switching converter-fed DC motor drives [PDF]
, 1998 Two new soft-switching DC-DC power converters, with the capabilities of bidirectional power flow and soft-switching (either zero-voltage transition or zero-current transition) are developed for DC motor drives.

Minimum Current Optimization of DBSRC Considering the Dead-Time Effect
Energies, 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 ...

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.

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 ...

A novel soft switching crossing current resonant converter (XCRC) [PDF]
, 1994 Unlike other resonate or soft-switching converter, this novel topology employs only two switches and a very simply control method. The inherent constant power protection feature is another merit. No special resonate chip is needed to control the circuit.

Molecular Oncology, EarlyView.Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...
