Zero‐voltage‐switching buck converter with low‐voltage stress using coupled inductor [PDF]
IET Power Electronics, 2016 This study presents a new zero‐voltage‐switching (ZVS) buck converter. The proposed converter utilises a coupled inductor to implement the output filter inductor as well as the auxiliary inductor which is commonly employed to realise ZVS for switches.

A Family of Transformerless Quadratic Boost High Gain DC-DC Converters
Energies, 2021 This paper presents three new and improved non-isolated topologies of quadratic boost converters (QBC). Reduced voltage stress across switching devices and high voltage gain with single switch operation are the main advantages of the proposed topologies.

Coalescence of electrically charged liquid marbles [PDF]
, 2017 © The Royal Society of Chemistry. In this work, we investigated the coalescence of liquid water marbles driven by a DC electric field. We have found that two contacting liquid marbles can be forced to coalesce when they are charged by a sufficiently high

Pulsed voltage stress on thin oxides
Electronics Letters, 2000 Stress-induced leakage current (SILC) is one of the major problems found in ultra-thin oxides before the onset of soft or catastrophic breakdown during accelerated life tests. Quite often SILC is measured after constant current (CCS) or constant voltage (CVS) stresses, even though during the device life the operating conditions usually involve ...

Capacitive Power Transfer System with Reduced Voltage Stress and Sensitivity
Applied Sciences, 2018 This paper introduces a DC–DC buck converter on the secondary side of the capacitive power transfer system to reduce the voltage and electric field across the interface, and to reduce the circuit Q, and thus the system sensitivity.
