Vibration and noise mechanism of a 110 kV transformer under DC bias based on finite element method
Global energy and environmental issues are becoming increasingly problematic, and the vibration and noise problem of 110 kV transformers, which are the most widely distributed, have attracted widespread attention from both inside and outside the industry.

Loss Calculation of a High Power DC-DC Converter Considering DC Bias Characteristic of Inductor [PDF]
It is necessary to accurately predict converter losses for optimized design of a high-power DC-DC converter. The losses of switching devices and inductor among the elements of the converter take significantly greater proportion. The current ripple will be determined by the size of the inductance and this inductance value varies depending on the DC ...

Decoherence Driven Quantum Transport
We propose a new mechanism to generate a dc current of particles at zero bias based on a noble interplay between coherence and decoherence. We show that a dc current arises if the transport process in one direction is maintained coherent while the ...

Tunable sensor response by voltage-control in biomimetic hair flow sensors [PDF]
We present an overview of improvements in detection limit and responsivity of our biomimetic hair flow sensors by electrostatic spring-softening (ESS). Applying a DC-bias voltage to our capacitive flow sensors improves the responsively by up to 80% for ...

Objective Social determinants of health (SDOH) contribute to juvenile idiopathic arthritis (JIA) disparities, but most studies have assessed SDOH independently rather than cumulatively across individual, family, and neighborhood levels. Using a socioecological framework, we investigated the relationship among cumulative social disadvantage ...

The transient DC bias current will be generated when the input voltage or load of the dual active bridge (DAB) converter suddenly changes, resulting in the excessive peak value of the inductor current and saturation of the transformer core.

Delocalization and spreading in a nonlinear Stark ladder
We study the evolution of a wave packet in a nonlinear Schr\"odinger lattice equation subject to a dc bias. In the absence of nonlinearity all normal modes are spatially localized giving rise to a Stark ladder with an equidistant eigenvalue spectrum and ...
