  • Overvoltage limitation in a switch-mode converter
    Patent number: 8891265
    Abstract: A switch-mode converter including an inductive transformer having a secondary winding associated with at least one first switch, including, in parallel with the first switch, at least one first diode in series with a capacitive element; and in parallel with the capacitive element, an active circuit for limiting the voltage thereacross.
    Type: Grant
    Filed: May 12, 2009
    Date of Patent: November 18, 2014
    Assignee: STMicroelectronics (Tours) SAS
    Inventors: Bertrand Rivet, Aurélien Hamadou
  • Switched-mode power supply including switch protection circuit
    Patent number: 8593116
    Abstract: A switched-mode converter includes a first magnetic circuit including a first inductive element, coupled to at least one second inductive element and electrically coupled in series with the second element and with a first diode between a first one of two input terminals and a first one of two output terminals; a first switch coupled in series with a third inductive element between a second terminal of the first inductive element and a second input terminal, a common node between the first switch and the third inductive element being connected to one of the output terminals by a second diode; and a circuit capable of canceling the voltage across the first switch before its turning-on.

  • SWITCHED-MODE POWER SUPPLY
    Publication number: 20100237843
    Abstract: A switched-mode converter including a first magnetic circuit including a first inductive element, coupled to at least one second inductive element and electrically in series with this second element and with a first diode between a first one of two input terminals and a first one of two output terminals; a first switch in series with a third inductive element between a second terminal of the first inductive element and a second input terminal, a common node between the first switch and the third inductive element being connected to one of the output terminals by a second diode; and a circuit capable of canceling the voltage across this first switch before its turning-on.
