  • Passivity-based switching power supply system, controller, and control method
    Patent number: 10978951
    Abstract: In a case where passivity-based control is applied to a plurality of circuits connected in parallel, a simpler target state is used. A switching power supply system includes: a plurality of switching power supply circuits connected in parallel to a load R; and a controller configured to switch each of the plurality of switching power supply circuits, through passivity-based control, by using a sum of currents that flow in the plurality of switching power supply circuits.
    Type: Grant
    Filed: April 6, 2018
    Date of Patent: April 13, 2021
    Assignee: Kyoto University
    Inventors: Takashi Hikihara, Yuhei Sadanda
