IPC: G06F17/30
Filed: 2010-03-31
Abstract: Aspects of a data environment, such as the creation, provisioning, and management of data stores and instances, are managed using a separate control environment. A user can call into an externally-facing interface of the control environment, the call being analyzed to determine actions to be performed in the data environment. A monitoring component of the control plane also can periodically communicate with the data environment to determine any necessary actions to be performed, such as to recover from faults or events in the data environment. A workflow can be instantiated that includes tasks necessary to perform the action. For each task, state information can be passed to a component in the data environment operable to perform the task, until all tasks for an action are completed. Data in the data environment can be accessed directly using an externally-facing interface of the data environment, without accessing the control plane.

Abstract: A high/low voltage conversion star-type multiphase variable-frequency driving system relates to a high-voltage high-power motor and driving control thereof. A variable-frequency driving technical solution commonly used at present mainly focuses on adding a frequency converter to a conventional motor, resulting in short insulation life of the motor and a poor heat dissipation capability of the motor. The present invention comprises a phase-shifting transformer, rectifier circuits, inverter circuits, multiphase motors, and a control circuit connected with the phase-shifting transformer, the rectifier circuits, the inverter circuits, and the multiphase motors. A primary winding of the phase-shifting transformer is connected to an alternating current power supply, and secondary windings of the phase-shifting transformer are connected to the rectifier circuits, wherein: the number of the secondary windings is the same as that of the rectifier circuits, one secondary winding is connected with one rectifier circuit; the rectifier circuits form a common-ground direct-current power supply by means of common ground connection; an output end of the rectifier circuit is connected to the inverter circuit. The present technical solution realizes a high voltage and a large current, and meanwhile simplifies the structure, reduces insulation requirements, improves heat dissipation of motors, and increases the power density.
