  2. Metal matrix composite - Wikipedia

    en.wikipedia.org/wiki/Metal_matrix_composite

    The MMC driveshaft has become a common modification for racers, allowing the top speed to be increased far beyond the safe operating speeds of a standard aluminum driveshaft. Honda has used aluminum matrix composite cylinder liners in some of their engines, including the B21A1 , H22A and H23A , F20C and F22C , and the C32B used in the NSX .

  3. Static synchronous compensator - Wikipedia

    en.wikipedia.org/wiki/Static_synchronous_compensator

    MMC topology for a single phase, with a DC bus. The diagram shows switches, which would be replaced with some type of IGBT arrangement in a VSC. While adding phase shifting to three-level converters improves harmonic performance, it comes at the cost of adding 2, 3 or even 4 additional STATCOMs.

  4. Multi-level converter - Wikipedia

    en.wikipedia.org/wiki/Multi-level_converter

    A multi-level converter (MLC) or (multi-level inverter) is a method of generating high-voltage wave-forms from lower-voltage components. MLC origins go back over a hundred years, when in the 1880s, the advantages of DC long-distance transmission became evident.

  5. Amplifier figures of merit - Wikipedia

    In electronics, the figures of merit of an amplifier are numerical measures that characterize its properties and performance. Figures of merit can be given as a list of specifications that include properties such as gain , bandwidth , noise and linearity , among others listed in this article.

  6. Milling (machining) - Wikipedia

    en.wikipedia.org/wiki/Milling_(machining)

    The distinction, when one is made, is that a machining center is a mill with features that pre-CNC mills never had, especially an automatic tool changer (ATC) that includes a tool magazine (carousel), and sometimes an automatic pallet changer (APC). In typical usage, all machining centers are mills, but not all mills are machining centers; only ...

  8. MultiMediaCard - Wikipedia

    en.wikipedia.org/wiki/MultiMediaCard

    In 2004, the Reduced-Size MultiMediaCard (RS-MMC) was introduced as a smaller form factor of the MMC, with about half the size: 24 mm × 18 mm × 1.4 mm. The RS-MMC uses a simple mechanical adapter to elongate the card so it can be used in any MMC (or SD) slot. RS-MMCs are currently available in sizes up to and including 2 GB.
