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.

Abstract: A cooling system is provided for electrical components in which cooling assemblies (11, 45) are inserted in non-magnetic cores of the electrical components, and in which tubes provide both inflow and outflow of a cooling medium. The non-magnetic cores may be bobbins (30) for an inductor assembly or the core of a capacitor (40). The tubes may form a loop (11) in more than one plane to prevent inducing current in a single turn, or they may be split-flow closed-end tubes (45) inserted from one end of the electrical component. The bobbin cores (31) are also constructed with a non-conductive portion to prevent inducing a current in a single turn of a conductor.

Abstract: A cooling system (11) is provided for electrical components (10, 90) in which passageways (21) are inserted in non-magnetic cores of the electrical components, and in which the passageways (21) provide both inflow and outflow of a cooling medium. The passageways (21) can be formed by drilling holes in a core of an electrical component or by mounting closed-end tubes (16-19) on a base plate-cooling manifold (20) or can be part of a conduit assembly (70). The tubes (16-19, 71) are split-flow closed-end tubes inserted from one end of the electrical component (10, 90). The tubes and passageways (16-19, 21, 71) may be partitioned into two halves or into two concentric portions. O-ring seals (28) are provided around the base of the tubes to seal the areas where the passageways communicate with hollow portions of base plates for supplying the cooling medium.

Abstract: EMI shielding in an electric vehicle drive is provided for power electronics circuits and the like via a direct-mount reference plane support and shielding structure. The thermal support may receive one or more power electronic circuits. The support may aid in removing heat from the circuits through fluid circulating through the support. The support forms a shield from both external EMI/RFI and from interference generated by operation of the power electronic circuits. Features may be provided to permit and enhance connection of the circuitry to external circuitry, such as improved terminal configurations. Modular units may be assembled that may be coupled to electronic circuitry via plug-in arrangements or through interface with a backplane or similar mounting and interconnecting structures.

Abstract: A bus system is disclosed for use with switching devices, such as power electronic devices. The system includes generally parallel bus elements that define electrical reference planes, such as for a dc bus. The bus elements are separated from one another by insulative layers, with additional insulative layers being available for separating the system from other circuit components. Portions of the bus elements are extended or exposed to permit connection to the circuit elements, including packaged switching circuits and energy storage or filtering circuits. The bus system may be conformed to a variety of geometric configurations, and substantially reduces parasitic inductance and total loop inductance in the resulting circuitry.
