PERLE: A High Power Energy Recovery Facility

2019
PERLE is a proposed high power Energy Recovery Linac, designed on multi-turn configuration, based on SRF technology, to be hosted at Orsay-France in a col-laborative effort between local laboratories: LAL and IPNO, together with an international collaboration involv-ing today: CERN, JLAB, STFC ASTeC Daresbury, Liverpool University and BINP Novosibirsk.

Optimal efficiency slip-power recovery drive

IEEE Transactions on Energy Conversion, 1988
A technique for the optimization of efficiency by using the minimization of global losses of the doubly fed induction motor in slip power recovery drives is presented. The optimal control algorithm is deduced and one programmable open-loop controller is proposed for its realization.

Energy recovery for low-power CMOS

Proceedings Sixteenth Conference on Advanced Research in VLSI, 2002
Energy recovery, as a means to trade off power dissipation for performance in CMOS logic circuits, is analyzed and investigated. A mathematical model is presented to estimate the efficiency for two energy-recovery approaches under varying conditions of voltage swing, transition time, and MOS device parameters. This model can be directly compared to the

A low-power misprediction recovery mechanism

2009 Asia Pacific Conference on Postgraduate Research in Microelectronics & Electronics (PrimeAsia), 2009
In modern superscalar processor, branch misprediction penalty becomes a critical factor in overall processor performance. Previous researches proposed dual (or multi) path execution methods attempt to reduce the misprediction penalty, but these methods are quite complex and high power consumption.

Power-aware Recovery for Geographic Routing

2009 IEEE Wireless Communications and Networking Conference, 2009
Maintaining low power consumption is critical in wireless ad hoc and sensor networks. With packet transmissions and retransmissions consuming much of the energy resources in wireless networks, it becomes important to minimize the number of transmissions associated with the end-to-end delivery of packets.

Power circuit breaker transient recovery voltages

IEEE Transactions on Power Apparatus and Systems, 1976
This paper describes the effects of the system zero-sequence network impedances and bus capacitance on circuit breaker transient recovery voltage requirements for EHV systems. Three basic types of faults are considered: three-phase-to-ground terminal faults, three-phase ungrounded terminal faults, and short line faults.

Expansion Power Recovery in Refrigeration Systems

2015
Vapor-compression systems are the most popular method of refrigeration. However, the throttling loss at the expansion valve is one of the “energy parasites” of such systems. This is especially acute in systems with large operating pressure differences like the transcritical CO2 refrigeration systems.

Recovery of high power water switches

Conference Record of the Twenty-Sixth International Power Modulator Symposium, 2004 and 2004 High-Voltage Workshop., 2005
The recovery of water switches is determined by the expansion and decay of a vapor bubble that is generated and driven by the energy dissipated in the switch medium during switch closure. Shock waves that also carry away energy propagate through the switch volume much faster and have faded away before the vapor bubble reaches its maximum expansion. For

PRESSURE POWER RECOVERY DEVICE

2010
A power recovery device, including an electroactive polymer membrane; an actuator capable of moving along a first direction non-parallel to the mid-plane of the membrane; a member for converting the motion of the actuator into a stretching of the membrane along at least one second direction of the mid-plane of the membrane; and means for biasing the ...
