    A lightweight and high efficiency battery charger for electric vehicles by Yue, Xi Tong

    Published 2015
    “…This auxiliary circuit reactive current is achieved so that zero-voltage switching is guaranteed. Besides, voltage spikes across the output diode bridge of FB converter are eliminated by using two clamp diodes in the circuit, which leads to lower power loss and lower rating of the diodes and output filter capacitor. …”

    Piezoelectric single crystal based one-dimensional phased array for breast tissue imaging by Du, Wenya

    Published 2024
    “…In this thesis, I propose a conformable ultrasound breast patch (cUSBr-Patch) consisting of a one-dimensional (1D) phased array and a nature-inspired patch design, which offers large-area, deep tissue scanning and multi-angle, repeatable breast imaging while avoiding the drawbacks of conventional ultrasound imaging technologies. I used a Yb/Bi-doped PIN-PMN-PT single crystal as the active element due to its superior piezoelectric properties (d33 = 2,800 pC/N, εr = 7,000, k33 = 0.93). …”
