    摘要: A method of assembling and providing an electric power apparatus. The method uses a heat resistant housing having a structure adapted to accommodate and retain a power circuit card and also including a bracket adapted to accommodate and constrain a rigid conductive member. A power circuit card having an electrical terminal is placed into the housing and a rigid conductive member into the bracket. The rigid conductive member is flow soldered to the electrical terminal, thereby exposing the heat resistant housing to heat and creating a solder bond. Finally, the rigid conductive member is affirmatively connected to the housing. The bracket constrains the rigid conductive member so that the act of affirmatively connecting does not weaken the solder bond.

    摘要: A structurally robust power switching assembly, that has a power transistor, comprising a thin and delicate layer of metal oxide, and a major surface of the layer of metal oxide being substantially coincident with a major surface of the power transistor, the major surface of the power transistor defining both an emitter and a gate. Also, dielectric material is placed over a portion of the emitter, so that it abuts the gate and a highly conductive pillar is constructed out of a relatively soft material, supported by the gate and the dielectric material, so that it has a larger area than would be possible if it was supported only by the gate.

    摘要: A heat producing, fluid cooled assembly that includes a housing made of liquid-impermeable material, which defines a fluid inlet and a fluid outlet and an opening. Also included is an electrical package having a set of semiconductor electrical devices supported on a substrate and the second major surface is a heat sink adapted to express heat generated from the electrical apparatus and wherein the second major surface defines a rim that is fit to the opening. Further, the housing is constructed so that as fluid travels from the fluid inlet to the fluid outlet it is constrained to flow past the opening thereby placing the fluid in contact with the heat sink.

    摘要: A physical construction of an inverter of the type having a positive voltage line and a negative voltage line interconnected by one or more switch sections. Each section includes two switch circuits, each having a transistor in parallel with a diode. The two switch circuits are connected in series, with the connection between the circuits providing an output to drive a load. The positive voltage line includes a positive voltage rail positioned closely to a negative voltage rail which is part of the negative voltage line. The close proximity of the two rails causes an electrical coupling between the positive and negative voltage lines. Current paths including circuit traces and bond wires within the inverter are arranged to place paths having oppositely directed currents, or equal and opposite di/dt's, in close parallel proximity resulting in mutual coupling and reduction in parasitic inductances. This construction results in a substantial reduction in the inductances of the various lines, with a corresponding reduction in switching voltage peaks, and an increased power and operational frequency capability.
