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 ...

1. Severe voltage fluctuations: Under conditions such as motor acceleration and energy recovery, the system voltage may ...

Power over coax (PoC) works by transmitting both data and power over a single coaxial cable, reducing wiring, weight, and ...

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 ...

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 ...

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 ...
