  • Publication number: 20190315233
    Abstract: A power conversion system for vehicles is provided. The system includes a switching circuit having first input/output terminals, second input/output terminals and a plurality of switching elements connected between the first input/output terminals and the second input/output terminals. A first energy storage device is connected to the second input/output terminals and has a preset charging/discharging voltage. A first voltage conversion circuit converts power output from the first input/output terminals to output a voltage less than the voltage of the first energy storage device. A second energy storage device is charged/discharged with the output voltage of the first voltage conversion circuit. A controller controls open/short-circuit states of the switching elements based on whether the first energy storage device is being charged and whether the vehicle is traveling.

  • Patent number: 10411266
    Abstract: Provided are: a dry reforming catalyst, in which a noble metal (M) is doped in a nickel yttria stabilized zirconia complex (Ni/YSZ) and an alloy (M-Ni alloy) of the noble metal (M) and nickel is formed at Ni sites on a surface of the nickel yttria stabilized zircona (YSZ); a method for producing the dry reforming catalyst using the noble metal/glucose; and a method for performing dry reforming using the catalyst. The present invention can exhibit a significantly higher dry reforming activity as compared with Ni/YSZ catalysts. Furthermore, the present invention can have an improved long-term performance by suppressing or preventing the deterioration. Furthermore, the preparing method is useful in performing the alloying of noble metal with Ni at Ni sites on the Ni/YSZ surface and can simplify the preparing process, and thus is suitable in mass production.

  • Publication number: 20190157959
    Abstract: Provided is an impact type vibration actuator including a permanent magnet having a stopper insertion portion; a linear guide surrounding the permanent magnet; a stopper protruding into the linear guide and inserted into the stopper insertion portion; and coils provided on at least one end of the permanent magnet to provide alternately attraction and repulsion to the permanent magnet. According to the present invention, since a permanent magnet is not connected to the vibration mass, it is possible to adjust the vibration frequency in a very wide range by adjusting the frequency of the power source applied to the coil, and to adjust vibration intensity by appropriately selecting current intensity, a stopper interval, an elastic means, and the like. In addition, through this, it is possible to provide much more various haptic feedbacks than the prior art.
