  • Patent number: 12265299
    Abstract: The invention provides a method for preparing a nanosized mixed crystal of cyanuric acid-coated halide perovskite, and use thereof. The method includes: (1) dispersing cesium halide, a lead salt, and urea in water, and stirring to obtain a mixed solution; and (2) adding phosphoric acid to the mixed solution, and subjecting to microwave heating, to obtain a solid after water is evaporated off, which is allowed to stand to obtain the nanosized mixed crystal of cyanuric acid coated halide perovskite. The method is simple, reproducible, and low in cost, with which mass production is achievable, and the emission wavelength of the obtained product is adjustable within a certain range through heat treatment. Due to the passivation and protection effects of cyanuric acid on halide perovskite, the prepared nanosized mixed crystal has excellent luminescence performance and stability, and is useful in the preparation of a high-color-point quantum dot brightness enhancement film.

  • Patent number: 12224668
    Abstract: A boost converter has a main energy storage inductor and a main GaN boost switch with a node between them. A pre-charging switch is connected at the output side of the main boost switch and the inductor, between the node and an output capacitor. The pre-charging switch comprises a body diode in the forward direction from the output capacitor to the node. The output capacitor is charged by the pre-charging switch in a pre-charge phase and this provides a soft start-up to avoid large inrush currents. A third switch, which is also a GaN switch, is in series with the pre-charging switch to provide synchronous output rectification. The third switch has a body diode in a forward direction from the node to the output capacitor. In the pre-charge phase, both the boost switch and third switch are turned off whereas in a subsequent boost phase, the pre-charging switch is turned constantly on, and alternately the boost switch and the third switch are turned on and off to implement the boost conversion.

  • Publication number: 20230387902
    Abstract: A driver circuit is for driving a GaN power commutation switch of a switch mode power converter. A sensing component is connected to the GaN switch for sensing a parameter such as a peak current of the power commutation. An energy storage component provides a certain turn on voltage between the gate and source of the GaN switch. The charging and discharging of the energy storage component is regulated, and the sensing is disabled with timing which is synchronized with the charging and discharging function of the energy storage component. It is prevented that a voltage across the sensing component reduces the generated gate-source drive voltage of the GaN switch.
