  • Controller for complementary switches of a power converter and method of operation thereof
    Patent number: 7095638
    Abstract: A controller for, and related method of, controlling first and second alternately conducting switches of a power converter. In one embodiment, the controller includes a sensing circuit configured to sense a parameter representative of an input voltage of the power converter. The controller also includes a modification circuit configured to alter a drive signal to one of the first and second switches thereby modifying a delay between conduction intervals of the first and second switches as a function of the input voltage.

  • Arrangement of switched-mode power supplies connected in parallel without a separation diode
    Patent number: 6121759
    Abstract: An arrangement of switched-mode power supplies is disclosed. The arrangement includes at least two switched-mode-type power supplies that are provided with a transformer and that have outputs connected in parallel without a separation diode at the output of each power supply. Each parallel-connected switched-mode power supply includes means for generating in a reference voltage output a voltage that is proportional to the pulse duty factor of the secondary voltage of the transformer. The reference voltage outputs of each switched-mode power supply are connected in parallel. Each parallel-connected switched-mode power supply also includes means for detecting a current that flows through the reference voltage output, and for generating a correction voltage proportional to this current in order to correct the output voltage of the switched-mode power supply.
