  • Patent number: 11865674
    Abstract: A positioning fixture including a shielding member and a driving member is provided. The shielding member includes a sliding part slidably connected to a functional module, a guiding part, and a shielding part. The sliding part and the shielding part respectively extend from two opposite ends of the guiding part. The driving member is movably disposed on the functional module corresponding to the shielding member. The driving member includes a base part, a driving part that contacts the guiding part, and a pillar part, which protrudes from the base part and is adapted to pass through the guiding groove. When the functional module is positioned on the circuit board, the base part of the driving member is pushed by the electronic component, and the guiding part is pushed by the driving part, so that the shielding member slides and the shielding part shields a screw hole of the circuit board.

  • Patent number: 11863071
    Abstract: A power converter having a smooth transition control mechanism is provided. An oscillator circuit outputs a clock signal. A control circuit receives the clock signal from the oscillator circuit and outputs a control signal based on the clock signal. A driver circuit outputs a high-side conduction signal and a low-side conduction signal according to the control signal. A high-side switch is turned on or off according to the high-side conduction signal from the driver circuit. A low-side switch is turned on or off according to the low-side conduction signal from the driver circuit. The oscillator circuit receives the high-side conduction signal from the driver circuit. The oscillator circuit, according to the high-side conduction signal, determines whether or not the clock signal outputted to the control circuit needs to be adjusted.
