  • Patent number: 7638983
    Abstract: Disclosed is a controller of a grid coupled type doubly-fed induction generator having a multi-level converter topology, which can control the doubly-fed induction generator having a high voltage specification and can perform a fault ride-through function, an anti-islanding function and a grid voltage synchronization function required for a dispersed power generation facility. The controller makes a H-bridge multi-level converter generate a three-phase voltage waveform resulted from the structure that single-phase converters each being composed of a 2-leg IGBT are stacked in a serial manner, and controls a rotor current so as to make the rotor coil of the doubly-fed induction generator in charge of a slip power only. The boost converter is composed of a 3-leg IGBT and a boost inductor generating a direct current voltage of its source required for the H-bridge multi-level converter.

  • Patent number: 7616056
    Abstract: Provided is an operational transconductance amplifier (OTA). An existing Nauta transconductor used to implement a high frequency Gm-C filter integrated circuit (IC) is analyzed by a new method and from a new perspective to remove extra components and divide roles of remaining inverters for more simple and efficient circuit structure. In an existing Nauta transconductor, a common mode signal from an input terminal is amplified and appears at an output terminal, while in the inventive Nauta transconductor the common mode signal from an input terminal does not appear at the output terminal and is effectively eliminated. These enhanced characteristics can be achieved with a smaller number of inverters than an existing Nauta transconductor. Frequency characteristics of the filter can be effectively enhanced by independently controlling the quality factor without affecting the transconductance value required for frequency characteristics of the filter.

  • Publication number: 20080211707
    Abstract: A slider-activated vehicle remote controller incorporates a sliding mechanism to enable locking and/or unlocking of a vehicle. Either a straight-path slide movement or an axis-based slide movement can be used as the sliding mechanism for the slider-activated vehicle remote controller, wherein a direction of the sliding movement or a particular position of the sliding mechanism of the slider-activated vehicle remote controller can be configured to indicate the vehicle's locked and/or unlocked status. Therefore, by looking at the current shape of the slider-activated vehicle remote controller, a user can readily identify whether the vehicle is locked or unlocked. In one embodiment of the invention, the sliding mechanism acts as a switch to trigger locking and/or unlocking of the vehicle. In another embodiment of the invention, the sliding mechanism activates an underlying switch to trigger locking and/or unlocking of the vehicle.
