  • Single stage buck-boost inverter with step modulation
    Patent number: 11996788
    Abstract: Disclosed is a novel and innovative class of buck-boost bidirectional inverters achieve ultra high efficiency in applications requiring converting of one or more low and variable DC voltages of one or more power sources (which may include a battery, a low-voltage DC source, or a set of PV solar panels) to an AC voltage (e.g., connected to a grid) through a single-stage power conversion with step modulation.
    Type: Grant
    Filed: September 15, 2021
    Date of Patent: May 28, 2024
    Assignee: Redx Technology Australia Pty Ltd
    Inventors: Xue Jian Chen, Jin Chuan Huang
  • Semiconductor device and method for fabricating the same
    Patent number: 11968906
    Abstract: A method for fabricating a semiconductor device includes the steps of: forming a first inter-metal dielectric (IMD) layer on a substrate; forming a contact hole in the first IMD layer; forming a bottom electrode layer in the contact hole; forming a magnetic tunneling junction (MTJ) stack on the bottom electrode layer; and removing the MTJ stack and the bottom electrode layer to form a MTJ on a bottom electrode. Preferably, the bottom electrode protrudes above a top surface of the first IMD layer.
