Interleaved DC/DC Boost Converter with Coupled Inductors

open access: yesAdvances in Electrical and Electronic Engineering, 2018
This paper deals with the analysis of boost interleaved DC-DC converter with a coupled inductor on the same magnetic core. The advantage of the coupled inductor over the non-coupled case is investigated. The ripple current equations as an input current for the boost operation mode and the ripple current in individual phase of the interleaved converter ...

3D Large‐Scale Subwavelength‐Resolution Sound Sheet Tomography Based on an Active and Programmable Circular Meta‐Array

open access: yesAdvanced Science, EarlyView.
A programmable 2048‐element circular ultrasound array combined with a compact acoustic lens produces a thin “sound sheet” over a large field of view, and records echoes with wide angular diversity across the ring aperture. Coherence‐enhanced beamforming converts full‐matrix data into high‐contrast tomographic slices, delivering near‐diffraction‐limited
