Abstract: This paper explores generalized output impedance models and develops a new performance-limit figure of merit (FOM) for switched-capacitor (SC) dc-dc converters that can be resonated or ...

From the May/June 2025 issue of Car and Driver. As good as the batteries of modern electric vehicles are, they still have drawbacks, such as their physical size and heft. Though the cost of EV ...

It’s a widely known problem with roots in urban legend: Devices with motherboards failing in the early 2000s with a sudden pop, a gruesome spill, or sometimes a burst of flames. And it was allegedly ...

While capacitance is the primary characteristic of capacitors, the concept of “capacitor resistance” is essential for understanding their real-world performance. Capacitors are fundamental components ...

A capacitor typically has two conductors separated by an insulating material. It may consist of aluminum foil interspersed with oil-impregnated paper or synthetic insulating materials. It facilitates ...

A new paper could give energy scientists a better way to design supercapacitors. Capacitors are a circuitry tool, and supercapacitors use them in a battery-like design. Batteries move energy using ...

Kelly has over 10 years of experience writing about home design and improvement for many prominent publications. She also spent several years working at a tech startup for an interior design game ...

Researchers believe they’ve discovered a new material structure that can improve the energy storage of capacitors. The structure allows for storage while improving the efficiency of ultrafast charging ...

A capacitor prototype with stratified 2D nanofillers embedded in the polymer matrix being tested in a University of Houston lab.Credits: University of Houston Dielectric capacitors are ubiquitous ...

Article 460 of the NEC provides the requirements for installing capacitors on electrical circuits [460.1]. It does not address surge capacitors or capacitors included ...

Rohm has developed its first silicon capacitors, the 400 x 200 x 185μm ( 01005, 0402 metric) BTD1RVFL series which covers 100pF to 1nF. “The mounting area is reduced by approximately 55% over general ...
