Embodiments of the present technology provide systems and methods for mounting a human interface module (HIM). According to various embodiments, the HIM may be configured to mount alternatively to a panel and a cradle. A panel mounting device is used to mount the HIM to a panel. The panel mounting device can be removably coupled to the HIM for panel mounting. The HIM may be installed in a cradle without the panel mounting device in accordance with some embodiments.

Human interface module mounting device

Motor drive power conversion systems are provided including a rectifier and a switching inverter, wherein the switching devices of the rectifier, the inverter and/or of a DC/DC converter are silicon carbide switches, such as silicon carbide MOSFETs. Driver circuits are provided for providing bipolar gate drive signals to the silicon carbide MOSFETs, including providing negative gate-source voltage for controlling the off state of enhancement mode low side drivers and positive gate-source voltage for controlling the off state of enhancement mode high side drivers.

Motor drive with silicon carbide MOSFET switches

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.

Bus connector system

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.

Multi-drive common control bus connector system

Power converter modules and parallel conversion systems are presented in which the modules are provided in a rollable enclosure having AC and DC electrical connections, and an interior including a switching circuit with switching devices individually connected between a corresponding AC node and a corresponding DC node for operation as either a rectifier or an inverter and an internal filter circuit with inductors individually connected between a corresponding AC node of the switching circuit and a corresponding AC electrical connection, with a built-in blower or fan to cool the filter circuit during operation.

Multifunction power converter with option for integrated magnetics

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.

DC pre charge circuit

Systems, methods, and devices are provided for coupling a direct current (DC) pre-charging circuit to a motor drive. In one embodiment, an industrial automation device may include an enclosed module that may include a pre-charge circuit. The pre-charge circuit may pre-charge a direct current (DC) bus. Further, the DC bus may couple to an inverter. The enclosed module may also include a power input that may couple the pre-charge circuit to a DC power source and an electrical output structure that may couple the pre-charge circuit to the inverter. Additionally, the pre-charge circuit may be removeably coupled to the inverter and the DC power source via a sliding action of the enclosed module.

Systems and methods for manufacturing a pre-charge circuit module

A motor drive unit including an enclosure, a bus bar supported by the enclosure, at least one modular power unit, and a flexible connector for electrically coupling the modular power unit with the bus bar. The flexible connector includes mating male and female connector portions each mounted to a respective one of the bus bar and the modular power unit, the connector portion mounted to the modular power unit being supported by a housing mounted to the modular power unit for movement relative thereto.

Flexible electrical power connection

The present invention provides a power converter mounting system including a flange that cooperates with a power converter and an enclosure. The flange includes a through hole that cooperates with an opening in the enclosure to permit the power converter to extend therethrough. A number of fasteners connect to the flange and overhang a portion of the power converter. The fasteners are configured to be manipulated from a front side of the power converter. An outer perimeter of the flange extends beyond the opening in the enclosure. The flange is secured to the enclosure with a number of fasteners that are also operable from the front side of the power converter. The power converter mounting assembly is configured to secure a power converter to an enclosure so as to satisfy a variety of sealing requirements as well as allowing convenient servicing of the power converter system.

Method and apparatus for mounting a power converter

An electric motor drive system includes a fan configured to cool power electronic components of the electric motor drive system. The electric motor drive system also includes a temperature sensor disposed proximate an air inlet of the fan and configured to sense an ambient temperature of air entering the air inlet. In addition, the electric motor drive system includes a processor communicatively coupled to the temperature sensor and configured to determine at least one of a drive prognostic and a derating requirement based on the sensed ambient temperature.

Method to implement drive diagnostics and prognostics automatically

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.
