  • Publication number: 20240120844
    Abstract: A resonant flyback power converter includes: a first and a second transistors which form a half-bridge circuit for switching a transformer and a resonant capacitor to generate an output voltage; a current-sense device for sensing a switching current of the half-bridge circuit to generate a current-sense signal; and a switching control circuit generating a first and a second driving signals for controlling the first and the second transistors. The turn-on of the first driving signal controls the half-bridge circuit to generate a positive current to magnetize the transformer and charge the resonant capacitor. The turn-on of the second driving signal controls the half-bridge circuit to generate a negative current to discharge the resonant capacitor. The switching control circuit turns off the first transistor when the positive current exceeds a positive-over-current threshold, and/or, turns off the second transistor when the negative current exceeds a negative-over-current threshold.

  • Patent number: 11953954
    Abstract: A variable holder module secures a variety of different expansion cards that may be installed within a computer or other information handling system. The holder module has a multi-sided component that is orientable according to which expansion card is to be secured within the computer. Each side of the component may thus correspond to a different one of the expansion cards. Once the expansion card is determined, a human or robotic picker need only orient component to the side that corresponds to the make/model of the expansion card. The holder module is thus adaptable to secure many different expansion cards that may be installed within the computer.
