Abstract: A matrix power conversion device including a plurality of three-phase switching modules and a controller is provided. Each three-phase switching module includes a plurality of bidirectional switches connected to the input phase voltages of the three-phase input power respectively and outputs a corresponding output phase voltage of the three-phase output power. The controller determines a maximum voltage, an intermediate voltage and a minimum voltage among all the input phase voltages to acquire a waveform of a control carrier wave in a switching cycle. The controller acquires output expected values corresponding to all output phase voltages and compares them with the waveform of the control carrier wave for acquiring a turning-on time of each of the plurality of bidirectional switches. Accordingly, the controller controls the matrix power conversion device to switch the three-phase input power so as to change the three-phase output power for driving the motor.

Abstract: Some embodiments provide a method for handling failure at one of several peer centralized components of a logical router. At a first one of the peer centralized components of the logical router, the method detects that a second one of the peer centralized components has failed. In response to the detection, the method automatically identifies a network layer address of the failed second peer. The method assumes responsibility for data traffic to the failed peer by broadcasting a message on a logical switch that connects all of the peer centralized components and a distributed component of the logical router. The message instructs recipients to associate the identified network layer address with a data link layer address of the first peer centralized component.

Each gate driver includes a drive resistance setting value. The waveform processing unit outputs a current absolute value waveform of an AC power. The weighting unit generates a trigger voltage.

When the gate driver receives the slew rate control signal, each of the gate drivers decreases the drive resistance setting value of the gate driver.

Abstract: Some embodiments provide a method for forwarding data messages at multiple edge nodes of a logical network that process data messages between a logical network and an external network. At a particular one of the edge nodes, the method receives a data message sent from a source machine in the logical network. The method performs network address translation to translate a source network address of the data message corresponding to the source machine into an anycast network address that is shared among the edge nodes. The method sends the data message with the anycast network address as a source network address to the external network. Each edge node receives data messages from source machines in the logical network and translates the source addresses of the data messages into the same anycast public network address prior to sending the data messages to the external network.

Abstract: A method to form a three-dimensional photonic crystal template with a gradient structure involves irradiating a photoresist composition of a thickness of at least 15 ?m from at least four laser beams to yield a periodic patterned with a percolating matrix of mass in constructive volumes of a cured photoresist composition and destructive volumes of voids free of condensed matter where the proportion of constructive volume displays a gradient from the irradiated surface to the substrate after development. For a given light intensity, photoinitiator concentration in the photoresist composition, and a given thickness, by irradiating for a relatively short period, a three-dimensional photonic crystal template displaying a gradient having greater constructive volume proximal the air interface forms and a relatively long irradiation period results in a gradient having greater constructive volume proximal the substrate.
