An extensible power supply control and monitoring system has been developed at Fermilab’s Technical Division to control and monitor power supplies of various types from within many different applications. This system, deployed as a network service, provides uniform programming and user interfaces for various types of power supplies, ranging from 20A to 30kA. 1 SYSTEM ORGANIZATION The Magnet Tes...

Many power supply manufacturers have found it economically feasible to make standard modular power supplies which are easily paralleled for higher current applications. If special provisions are not made to equally distribute the load current among the paralleled supplies, then one or more units will hog the load current leaving the other units essentially idle. This results in greater thermal ...

Heating, Ventilation, and Air Conditioning (HVAC) systems account for a significant portion of power consumption in commercial buildings all over the world [1, 4, 5, 6]. Since HVAC systems are designed for centralized cooling supplies, power consumption in each room is inestimable. Therefore, administrators are motivated to apportion the electricity payment for actual users. The even apportionm...

high and increasing beef marketing margin leads one to controversy about factors affecting it. this study using the monthly data for the 1998-2005 period to investigate the market power and to estimate how farm and marketing services supplies and retail demand determinants can affect beef marketing margin. the results show that farm, marketing services and retail level prices and thereby ma...

This paper reviews architectural and circuit design considerations for realization of low power dissipation in high-speed CMOS A/D converters. Basic limitations on achievable power dissipation in MOS samplers and quantizers is first discussed. Then a number of practical design aspects are illustrated with discussion of a 10-bit, 20-Msample/s pipeline A/D converter[1] implemented in 1.2-μm CMOS ...
