Abstract: A cooling member for a variable speed drive is disclosed. The cooling member includes including at least two channels, each channel including at least one inlet and at least one outlet, a first passageway configured to provide fluid to the at least two channels through the at least one inlet of each channel, a second passageway configured to receive fluid from the at least one outlet of each channel the at least two channels, and a connector to connect the cooling member to a second cooling member.

Abstract: A cooling member for a variable speed drive. The variable speed drive has a component that generates heat during operation of the drive and a base. The base has a surface that receives the component, a channel formed in the surface of the base and a passageway formed in the base and receiving fluid therethrough. Fluid flowing through the passageway provides cooling to the component and the base is manufactured from an injection molding process.

Abstract: Systems and methods for improved Variable Speed Drives are provided. One embodiment relates to apparatus for common mode and differential mode filtering for motor or compressor bearing protection when operating with Variable Speed Drives, including conducted EMI/RFI input power mains mitigation. Another embodiment relates to a method to extend the synchronous operation of an Active Converter to the AC mains voltage during complete line dropout. Another embodiment relates to an Active Converter-based Variable Speed Drive system with Improved Full Speed Efficiency. Another embodiment relates to a liquid- or refrigerant-cooled inductor. The liquid- or refrigerant-cooled inductor may be used in any application where liquid or refrigerant cooling is available and a reduction in size and weight of a magnetic component is desired.

Abstract: A plastic liquid cooled variable speed drive or inductor provided. The cooler provides lightweight, space conservative, corrosive free cooling to the components as well as provides a mounting area for modules. A cooler can be mounted to the core of an inductor to absorb heat generated by the core losses.
