Patent number: 5579217Abstract: A laminated bus assembly including a high power coupler to provide a low impedance, low noise laminated bus assembly for a switched converter that includes a plurality of switch pairs to convert between an AC power line and a DC device. The laminated bus assembly includes a first conductive layer, a second conductive layer, and a third conductive layer. A dielectric layer is laminated between each of the first, second, and third planes. The high power coupler includes a bushing positioned within the laminated assembly, including an engageable section for engaging with one of the conductive layers. A passage hole including an insulator ring is formed in intermediate conductive planes for passage of the bushing. A circuit layout includes a plurality of electrical connections between the switches, the AC, -DC and +DC bar conductors, and the DC device.Type: GrantFiled: November 15, 1994Date of Patent: November 26, 1996Assignee: Kenetech Windpower, Inc.Inventors: David Deam, William L.

Patent number: 5365424Abstract: A low impedance, low noise laminated bus assembly for a high power switched converter that has a plurality of switch pairs including a -DC switch and a +DC switch for high speed switching to convert between an AC power line and a DC power storage device such as capacitors. The laminated bus assembly includes a first conductor plane having a plurality of AC bar conductors for each phase of AC power, a second conductor plane including a -DC bar conductor, and a third conductor plane including a +DC bar conductor. A dielectric layer is laminated between the first, second, and third planes. The circuit layout includes a plurality of electrical connections between the switches, the AC, -DC and +DC bar conductors, and the DC power storage device. Some of the electrical connections require that a coupling conductor pass through another bar conductor, which must therefore be insulated from the coupling conductor.Type: GrantFiled: December 15, 1992Date of Patent: November 15, 1994Assignee: Kenetech Windpower, Inc.Inventors: David Deam, William L.

Patent number: 5172310Abstract: A low impedance, high power bus for conduction of electrical power with reduced transient signal effects is described herein. The high power bus can be applied as a high power supply bus between a constant voltage source and a plurality of switching cells positioning at varying locations along the bus, and as branch bus for the switching cells. The power bus can transmit high power: large currents in the hundreds or thousands of amperes, and large voltage potentials in the hundreds or thousands of volts. Particularly, the power bus has use in a DC-to-AC inverter that converts DC from a constant voltage source into three-phase AC for delivery to an electrical power grid. The high power bus includes two conductive bars positioned so that the current flow therethrough is balanced (equal and opposing), and the magnetic field is substantially confined between the bars. The bus includes a dielectric positioned between the conductive bars.Type: GrantFiled: July 10, 1991Date of Patent: December 15, 1992Assignee: U.S. Windpower, Inc.Inventors: David Deam, William L.
