  • Electrical insulation configuration for an electrical device
    Patent number: 9281905
    Abstract: An electrical insulation configuration for an electrical device having a power circuit includes a first insulation device to provide a level of basic insulation between the power circuit and a user, and an additive insulation device in series with the first insulation device, the additive insulation device to increase the level of basic insulation to a level of double insulation or reinforced insulation between the power circuit and the user.
    Type: Grant

  • Split laminated DC bus structure
    Patent number: 8947899
    Abstract: An apparatus and method for mounting additional components, such as capacitors, to a DC bus of a motor drive. In one aspect, a motor drive includes an enclosure defining an interior, an input for receiving input electrical power from a power source, an output for providing output electrical power to a load, an intermediate DC circuit including a DC bus located in the interior of the enclosure, and a modular capacitor bus electrically coupled with the intermediate DC circuit, the modular capacitor bus including at least one capacitor mounted thereto. The modular capacitor bus is mountable as a unit to the DC bus.

  • Power electronic module pre-charge system and method
    Patent number: 7830036
    Abstract: A power electronics device with an improved pre-charge circuit configuration is provided. More specifically, the input of the motor drive module may accept an AC or DC source voltage. In this way, the pre-charge circuit of the motor drive module may be utilized whether the motor drive is coupled to an AC or DC source.
