Here is a short tutorial on why DC/DC buck converters need capacitors on the input and how it works in a power design.

Matt Dore and the rest of Cambridge Audio’s engineering team explain that, after the run-in-induced relaxation of the suspension, roll surround and spider “reduces the resonance frequency, giving more ...

Abstract: In this paper, a variable-gain LLC converter with a series-parallel hybrid switch-controlled capacitor ... of resonant current to guarantee soft switching. Besides, a mode switching scheme ...

Abstract: This paper investigates the impact of resonant acoustic waves on the frequency noise spectrum of Distributed Feedback fiber lasers. A phase-shifted Fiber Bragg Grating is used to probe ...

The aluminum rod will produce a loud, clear tone that will last for a long time. You can also find the resonant frequencies of flexible pipe or hose. Listen with one end of the hose to your ear while ...

These metasurfaces can support surface waves with momentum bandgaps that lead to amplification. By time-modulating the surface’s resonance frequency, researchers achieved a broad bandgap, enabling ...

Resonant frequency is a fundamental property of LC circuits, which are formed by inductors (L) and capacitors (C). It is the frequency at which the inductive and capacitive reactances are equal, ...

Low-frequency insonation (<1 MHz) with NBs holds great potential in inducing significant bioeffects, making the monitoring of their acoustic response critical to achieving therapeutic goals. We ...
