Using electrochemical impedance spectroscopy (EIS) techniques to help obtain battery working conditions like SOH and SOC.

Abstract: This work presents a capacitor voltage balancing controller for current-controlled flying capacitor multilevel converters. A small-signal model of the converter derived from state–space ...

Abstract: There are various operating modes of parallel bipolar multi-terminal DC transmission systems, among which there is an asymmetric condition of unipolar-bipolar hybrid form. In this case, the ...

Nomographs are typically used in applications for which the modest level of accuracy they provide is sufficient and useful. Reality is that many real-world engineering situations require an answer ...

Radio experimenters often need a variable capacitor to tune their circuits, as the saying goes, for maximum smoke. In decades past these were readily available from almost any scrap radio, but the ...

Two DC stages DC-to-DC conversion typically starts with 48 V (or sometimes 54 V), and first drops it to 12 or 6 V. Then it is further dropped to the specific DC voltage that a chip requires. These two ...

Capacitors offer lower dissipation factor and reduced capacitance loss under DC bias, improving efficiency and reliability in high-voltage generators used for X-ray imaging, baggage scanning, air ...

In modern electrical systems, safety is of utmost importance to prevent hazards like electric shocks, fires, and damage to equipment caused by earth leakage currents. Earth leakage protection devices ...
