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 ...

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

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

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

Sensor array and magnetic actuation system guide and trigger the capsule, eliminating the need for onboard power. By changing the orientation and strength of the applied magnetic field, researchers ...

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 ...

Researchers at the University of California, Santa Cruz have developed a system that measures heart rate using WiFi signals without requiring any wearable devices. The method, called Pulse Fi, ...

Abstract: Fringing and proximity effects are the main reasons for serious ac copper loss in high-frequency planar inductors. In this article, a novel air-gapless core structure based on magnetic ...
