    摘要： Disclosed is a method of producing a polyolefin composition comprising contacting a metallocene pre-catalyst, a co-catalyst, a primary surrogate, and a secondary surrogate; adding a first olefin monomer; and polymerizing the first monomer for a time sufficient to form the polyolefin. Also disclosed is a method of producing a block polyolefin composition comprising contacting a metallocene pre-catalyst, a co-catalyst, a primary surrogate, and a secondary surrogate; polymerizing the first monomer for a time sufficient to form the polyolefin; adding a second monomer; and polymerizing the second olefin monomer for a time sufficient to form said block polyolefin composition. The method allows for the production of polyolefins of low molecular weights and narrow molecular weight distributions.

    摘要： Conduction loss in the body-diode of a low side MOSFET of a power switching stage of one phase of a coupled-inductor, multi-phase DC-DC converter circuit, associated with current flow in the output inductor of that one phase that is induced by current flow in a mutually coupled output inductor of another phase, during normal switching of that other stage, is effectively prevented by applying auxiliary MOSFET turn-on signals, that coincide with the duration of the induced current, to that low side MOSFET, so that the induced current will flow through the turned-on low side MOSFET itself, thereby by-passing its body-diode.

    摘要： An embodiment of a power supply includes an input node that receives an input voltage, an output node on which a regulated output voltage is provided, an odd number of magnetically coupled phase paths each coupled between the input and output nodes, and a first magnetically uncoupled phase path coupled between the input and output nodes. Such a power supply can improve its efficiency by activating different combinations of the coupled and uncoupled phase paths depending on the load conditions. For example, the power supply may activate only an uncoupled phase path during light-load conditions, may activate only coupled phase paths during moderate-load conditions, and may activate both coupled and uncoupled phase paths during heavy-load conditions and during a step-up load transient.

    摘要： An embodiment of an inductor assembly includes a core, a first conductor, and a second conductor. The core includes first and second members, a first group of one or more forms extending between the members, a second group of one or more forms extending between the members, and an isolating region that magnetically isolates the first group of forms from the second group of forms. The first conductor is wound about a first one of the forms in the first group, and the second conductor is wound about a second one of the forms in the second group. Such an inductor assembly may allow both coupled and uncoupled inductors to be disposed on a common core, thus potentially reducing the cost and size of the inductors as compared to the coupled inductors being disposed on one core and the uncoupled inductors being disposed on another core.
