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: Power conversion systems and filters therefor include conductive busbars, a first low frequency capacitor circuit coupled with the busbars at a first location proximate a filter input, a first inductor circuit with common mode cores extending around the busbars at a second location between the first location and a filter output, a second low frequency capacitor circuit coupled with the busbars at a third location between the second location and the filter output, a second inductor circuit with second common mode cores extending around the busbars at a fourth location between the third location and the filter output, a third low-frequency capacitor circuit coupled with the busbars at a fifth location between the fourth location and the filter output, and a high frequency fourth capacitor circuit, coupled with one of the busbars at the fifth location.

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.
