  • CASCADED H-BRIDGE INVERTER CAPABLE OF OPERATING IN BYPASS MODE
    Publication number: 20150357939
    Abstract: A cascaded H-bridge inverter capable of operating in bypass mode is disclosed where a bypass function can be performed through control of power switch, instead of allowing each unit power cell forming a cascaded H-bridge inverter to use a separate bypass switch, and a cell driver controls each power switch in a freewheeling mode to allow a current inputted to any output terminal to flow other output terminals when bypass function is to be performed for relevant unit power cell, whereby a stable operation can be performed even if there is no bypass switch at each unit power cell, and a cost saving can be accomplished, because an additional bypass switch such as a MC (Magnetic Controller) is not used.

  • METHOD FOR VOLTAGE DIP COMPENSATION OF INVERTER
    Publication number: 20150357936
    Abstract: Disclosed is a method for voltage dip compensation of inverter, the method including reducing an output frequency of an inverter to obtain a regenerative energy when it is determined that power failure has occurred during the inverter operation, adjusting increase/decrease of inverter output frequency in response to size of exceeding current and voltage based on an output current and DC-link voltage of the inverter, increasing the inverter output frequency in order to prevent excessive current flow when power restoration occurs at a power failure state, and returning to a speed prior to the momentary voltage dip by gradually increasing the inverter output frequency in a state where the inverter output frequency does not exceed an over-current limit by monitoring the inverter output frequency.

  • Forced Map Entry Flush to Prevent Return of Old Data
    Publication number: 20150347289
    Abstract: A data storage device flushes newly written data in response to certain events such that, when the device has acknowledged newly written data, the device cannot return old data of the referenced logical block address to the host in any case. If the data of the logical block address has been corrupted, the device returns an uncorrectable error, not old data. A “force map entry flush” flushes modified map entries to NAND when an upper page is programmed. After a power failure and restoration, a storage device is able to analysis map entries to determine whether there is some host data in the uncorrectable die, then prevent return of old data to a host.

  • Storage Controller and Method for Managing Metadata in a Cache Store
    Publication number: 20150347310
    Abstract: A cache controller coupled to a cache store supported by a solid-state memory element uses a metadata update process that reduces write amplification caused by writing both cache data and metadata to the solid-state memory element. The cache controller partitions the solid-state memory element to include a metadata portion, a host data or cache portion and a log portion. Host write requests that include “hot” data are processed and recorded by the cache controller. The cache controller maintains first and second maps. A log thread combines multiple metadata updates in a single log entry block. Pending metadata updates are checked to determine when a commit threshold is reached. Thereafter, the pending metadata updates are written to the solid-state memory element and the maps are updated.

  • SELECTING FLOATING TAP POSITIONS IN A FLOATING TAP EQUALIZER
    Publication number: 20150349988
    Abstract: In one embodiment, an apparatus has an equalizer, a tap position locator, and a tap weight updater. The equalizer has a plurality of floating taps. The tap position locator generates metrics for a set of possible tap positions of the equalizer. Each possible tap position corresponds to a different tap weight, and the metrics are generated without updating the tap weights for all of the possible tap positions in the set. Further, the tap position locator selects a subset of possible tap positions from the set based on the metrics. The tap weight updater updates a subset of the tap weights corresponding to the selected subset of possible tap positions, and applies the updated subset of tap weights to the plurality of floating taps.
