    Abstract: A cart is provided four extracting modular components from enclosures, and for inserting such components into enclosures. The cart may be specifically adapted for components of certain sizes and configurations. It may be used, for example, for extracting power electronic modular components from an electrical enclosure. The cart includes a support structure and an upright structure on which a carriage is movable. The carriage has elements that can extend below the modular component, to secure to the modular component, and to raise the modular component for extraction. Some or all of the interconnected elements of the cart may be foldable and collapsible for ease of storage and transport.

    Abstract: Systems and methods are provided for pre-charging the DC bus on a motor drive. Pre-charging techniques involve pre-charge circuitry including a manual switch, an automatic switch, and pre-charge control circuitry to switch the automatic switch between pre-charge and pre-charge bypass modes in response to an initialized pre-charge operation, input voltage sags, and so forth. In some embodiments, the pre-charge operation may be initialized by switching the manual switch closed. In some embodiments, the pre-charge operation may also be initialized by a detected voltage sag on the DC bus. The pre-charge circuitry may also be configured to disconnect to isolate a motor drive from the common DC bus under certain fault conditions.

    Abstract: The present invention relates generally to tuning the flow of cooling air across converter and inverter heat sinks in a motor drive system. More specifically, present techniques relate to motor drive duct systems including heat sinks with separate, sequential heat sink fin sections disposed in a common cooling air path and having different geometries to optimize the flow of cooling air across and between fins of the separate heat sink fin sections. For example, the heat sink fin sections may have different fin lengths, fin heights, fin counts, fin pitch (e.g., distance between adjacent fins), and so forth. Each of these different geometric characteristics may be tuned to ensure that temperatures and temperature gradients across the heat sinks are maintained within acceptable ranges.

    Abstract: An electrical bus assembly includes a frame and a plurality of bus bar carriers connected to the frame. The bus bars are supported by the bus bar carriers in parallel spaced-apart relation. A first retainer cap is secured to a first one of the plurality of bus bar carriers located adjacent a first end of the frame. A second retainer cap is secured to a second one of the plurality of bus bar carriers located adjacent a second end of the frame. The first and second retainer caps limit axial movement of the bus bars relative to the plurality of carriers sufficiently to prevent escape of the bus bars from the carriers. A bus bar connector is also disclosed for supplying power to or from the bus bars. An electrical bus system includes a first and second bus bar assemblies and a jumper connector assembly.
