  • Patent number: 9438124
    Abstract: A power supply circuit includes a plurality of output terminals that output voltages (voltages may have the same or different voltage values among the output terminals), and a transformer that has a plurality of output windings. First and second output windings of the plurality of output windings are coupled to each other. The first and second output windings have the same number of turns. First terminals, which have a first polarity, of the first and second output windings are connected to each other via a capacitor. Further, second terminals, which have a second polarity opposite to the first polarity, of the first and second output windings are electrically connected to each other. The second terminals of the first and second output windings may be directly connected to each other.

  • Publication number: 20160079870
    Abstract: A switching power supply device includes: a transformer; a first switch connected between a high potential terminal of an input DC voltage source and a primary winding; a second switch connected between a low potential terminal of the input DC voltage source and a primary winding; a control circuit outputting a driving pulse signal for synchronizing the first and second switches; first and second rectifying devices; a synchronous rectifier circuit; and a positive bias circuit that applies a positive bias to a control terminal of one of the first and second switches so as to constantly turn the one of the first and second switches ON. When the first and second switches stop a switching operation while an output voltage exists between the output terminals, the positive bias circuit applies the positive bias to the one of the first and second switches.

  • Publication number: 20160079871
    Abstract: A switching power supply device includes: a main transformer; a main switch that is connected between a high potential terminal of an input direct current voltage source and a primary-side main winding; a synchronous rectifier circuit includes: a rectifying switch that is connected to a secondary-side main winding in series and that is turned ON in synchronization with a turning ON state of the main switch and a commutation switch that is connected to the rectifying switch series circuit in parallel and that is turned ON in synchronization with a turning OFF state of the main switch; and an auxiliary switch circuit that turns the commutation switch OFF. When the main switch stops a switching operation while a voltage exists at a first output terminal on a high potential side, the auxiliary switch circuit turns the commutation switch OFF to prevent continuation of self-excited oscillation.

  • Publication number: 20150378240
    Abstract: A 2D/3D switchable stereoscopic display apparatus includes a display panel, a liquid crystal lens, and a control module. The liquid crystal lens is coupled with the display panel at a light-emitting side, and includes a first substrate having a plurality of first electrodes, a second substrate disposed opposite to the first substrate and having a second electrode, a liquid crystal layer constituting liquid crystal molecules disposed between the first substrate and the second substrate, and a plurality spacers. The control module is configured to, when the display apparatus is in a 2D display state, control a first voltage between the first electrodes and the second electrode to generate a first electric field with an equal electric field intensity, which causes the liquid crystal molecules to rotate by a predetermined degree such that a refractive index difference between the liquid crystal molecules and the spacers is within a preset range.

  • Publication number: 20150109549
    Abstract: A three-dimensional (3D) display apparatus is provided for displaying a 3D image. The 3D display apparatus includes a display panel and a grating device coupled to the display panel. The display panel includes a plurality of display pixels arranged in a two-dimensional array, and each pixel includes multiple sub-pixels. The grating device includes a plurality of grating elements based on liquid crystal to guide lights associated with the plurality of display pixels into predetermined viewing directions. Further, the grating device is one of a lenticular lens grating and a slit grating, and the plurality of grating elements are arranged in parallel. The plurality of grating elements cover the plurality of display pixels and are tilted at an inclination angle with respect to the display pixels, and each grating element comprises a plurality of electrodes arranged at the inclination angle.

  • Patent number: 8909868
    Abstract: A method and a system for controlling quality of service of a storage system, and a storage system. The method includes: collecting information about processing capabilities of the hard disks in the storage system and obtaining processing capabilities of the hard disks according to the information about processing capabilities; dividing a cache into multiple cache tiers according to the processing capabilities of the hard disks; and writing, for a cache tier in which dirty data reaches a preset threshold, data in the cache tier into at least one hard disk corresponding to the cache tier. The method avoids a phenomenon of preempting page resources in the cache.
