Adaptive on-time control for power factor correction stage light load efficiency

Номер: US20120014148A1
Автор: Chuanyun Wang, Fred C. Lee, Ming Xu, QIAN LI
Принадлежит: Virginia Tech Intellectual Properties Inc

Light load efficiency of a power factor correction circuit is improved by adaptive on-time control and providing for selection between a continuous conduction mode and a discontinuous conduction mode wherein the discontinuous conduction mode increases time between switching pulses controlling connection of a cyclically varying voltage to a filter/inductor that delivers a desired DC voltage and thus can greatly reduce the switching frequency at light loads where switching frequency related losses dominate efficiency. The mode for controlling switching is preferably selected for each switching pulse within a half cycle of the cyclically varying input voltage. A multi-phase embodiment allows cancellation of EMI noise at harmonics of the switching frequency and adaptive change of phase angle allows for cancellation of dominant higher order harmonics as switching frequency is reduced.

A business method to expand upon prior art methods of billing a utility customer's energy consumption from local power generation energy sources such as wind and solar systems. The invention discerns energy generated locally and energy consumed from a wide area energy source, utility or COOP. The invention allows power generated locally by leased, owned, or rented power generation equipment at the utility customer's location to be measured and billed to the customer at a separate rate than that charged by the utility to the customer. A well-engineered system will locally generate enough power to offset the utility's charges, lower the power customer's power costs and will provide revenue to the local power generation equipment provider by a power billing presented to the utility customer. The invention may utilize any power generation method such as electric, gas, oil, biomass, and or thermal.

Energy recovery in hot strip mills by converting the cooling heat of the continuous casting plant and the residual heat of slabs and coils into electrical enery or otherwise utilizing the captured process heat

Номер: US20120118526A1

Принадлежит: Sms Siemag AG

In hot strip plants, after casting, the residual heat of a partial quantity of the slabs has hitherto been used such that the slabs either are directly rolled or are placed warm or hot in the furnace. The remaining slabs normally cool after casting in a hall through which flows air and are stacked before their further transport. The same applies to the residual heat present in the coils after winding, which often cool in the coil-storage area in air. The cooling energy of the continuous-casting plant likewise escapes unused into the surroundings. In order to convert this unused solidification heat and residual heat into electric energy, it is proposed according to the invention that the slabs ( 10 ) are cast in a continuous-casting plant and the slabs ( 10 ) or coils are transported into the slab-storage area ( 12 ) or coil-storage area and during the casting in heat exchangers ( 31 ) and/or during the transport in heat exchangers ( 31 ) heat is extracted and/or there are deposited in part one on top of the other in specially prepared storage areas ( 30 ) provided with heat exchangers ( 31 ) for a short time or several hours, wherein in this transport period the cast billet or the slab ( 10 ) and/or in the storage period the residual heat of the slabs ( 10 ) or coils is transferred via heat conduction and thermal radiation and convection via the heat exchangers ( 31 ) into a heat-transfer medium such as, for example, thermal oil, and heats it, which then is discharged via heat-transfer transport lines ( 33 ) for power generation and/or direct use of the process heat by other heat consumers.

A wind-power and hydraulic generator apparatus has a wind power device, a drive device, multiple pump devices, a reservoir device and a hydraulic device. When the wind blows, the wind power device generates and stores electricity and the drive device drives the pump devices to pump water into the reservoir device. Then the reservoir device generates a water jet enabling the hydraulic device to generate electricity. When the wind does not blow, the electricity stored in the wind power device still enables the water to circulate and to generate the water jet. Whether the wind blows or not, the water of the reservoir device can keep circulating to generate the water jet and the hydraulic device can keep generating electricity. Accordingly, the wind-power and hydraulic generator apparatus can use wind power to generate a water jet.

On-chip interconnects with reduced capacitance and method of afbrication

Номер: US20120298411A1
Автор: Achyut Kumar Dutta
Принадлежит: Banpil Photonics Inc

An electronics interconnection system is provided with reduced capacitance between a signal line and the surrounding dielectric material. By using a non-homogenous dielectric, the effective dielectric constant of the material is reduced. This reduction results in less power loss from the signal line to the dielectric material, and therefore reduces the number of buffers needed on the signal line. This increases the speed of the signal, and reduces the power consumed by the interconnection system. The fabrication techniques provided are advantageous because they can be preformed using today's standard IC fabrication techniques.

Methods, apparatus, and computer program products are provided for managing tools and calibrating tools when performing assembly instructions in a computer directed assembly system. To ensure tools remain calibrated, in one embodiment a tool identifier associated with a tool required for the assembly instruction is obtained. Using the tool identifier, a tool usage time for the tool is aggregated from an assembly record database. To determine whether the tool may need calibration, the tool usage time from a last calibration point is compared with a tool usage threshold for calibrating the tool as provided for by the associated assembly instruction. If the tool usage threshold is exceeded, using the tool is disallowed unless the tool is recalibrated. Alternatively, the tool is authorized for use to perform the assembly instruction when it is determined that the tool usage time from the last calibration point does not exceed the tool usage threshold.

A wind turbine generator, or other energy extraction device, has a hydraulic circuit comprising a hydraulic pump driven by a rotating shaft and a hydraulic motor driving an electricity generator. When the electricity generator is switched off, it executes one or more pumping cycles to pressurise the high pressure manifold and therefore recover angular kinetic energy from the electricity generator rotor which can later be used to reaccelerate the electricity generator rotor to the correct operating speed for an electricity grid. Overall energy efficiency is increased and the minimum operating high pressure manifold pressure may be reduced as a result.
