  • Patent number: 11929684
    Abstract: Isolated power supply control circuits, isolated power supply and control method thereof are disclosed, the control circuit for controlling an isolated power supply includes a secondary-side control signal generator and a primary-side control signal generator. The secondary-side control signal generator produces a secondary-side transistor switch control signal containing information about a turn-off instant of a secondary-side synchronous rectification transistor, which serves as a second turn-on instant. The primary-side control signal generator derives, from a feedback signal, a supposed turn-on instant for a primary-side transistor switch, which serves as a first turn-on instant. The primary side turn-on signal generator further derives a turn-on instant for the primary-side transistor switch from the second or first turn-on instant whichever is later and responsively generates a primary-side transistor switch control signal.

  • Patent number: 11496934
    Abstract: The present disclosure relates to a mobile terminal for performing cell (re-)selection in a system with at least two suitable cells, each with a plurality of beams. The terminal is in a normal- or a high-mobility state. The terminal measures a signal quality of the beams of each of the suitable cells, determines the cell quality based on the respective measured signal qualities of the beams; and (re-)selects that cell based on a cell (re-)selection criterion using the determined cell qualities. The cell quality is determined for each one of the suitable cells as a sum of the measured signal quality of the beam, with the best signal quality, and a combined beam quality value for the other beams. The combined beam quality value is scaled with a scaling factor which changes depending on the mobility state such that the combined beam quality value is scaled-up in the high-mobility state and scaled-down in the normal-mobility state.
