Spear3 Large Dc Magnet Power Supplies
The Stanford Synchrotron Radiation Laboratory (SSRL) has successfully commissioned SPEAR3, its newly upgraded 3-GeV synchrotron light source. First stored beam occurred December 15, 2003 and 100mA operation was reached on January 20, 2004. This paper describes the specification, design, and performance of the SPEAR3 DC magnet large power supplies (LGPS) that consist of tightly-regulated (better...

متن کاملLow Noise Dc Power Supplies
− Some measuring systems are very sensitive on disturbances incoming from power supplies. If no accumulators are used for their power supply, which ensure a minimum signal noise and transmission jamming signal from power network, special power supplies have to be constructed for them. An example of a possible influence of a disturbance, which spreads along to the power supply on high pure sine-...
متن کاملSwitched Mode Power Supplies for DC to DC Conversion
Introduction The widespread use of battery operated portable devices such as cell phones and laptops has created the need for DC to DC conversion power supplies such as switched mode power supplies. According to an Electric Power Research Institute (EPRI) study [1], the amount of electricity that flowed through switched mode power supplies in 2004 was “6% of the national electric bill”. The pro...
متن کاملSystem-Level Requirements of DC-DC Converters for Dynamic Power Supplies of Power Amplifiers
The energy efficiency of battery-operated portable applications can be improved by increasing the efficiency of power amplifiers (PAs). By dynamically changing the supply voltage from the fixed battery supply using a DC-DC converter, the PA can be operated with high efficiency during power back-off. This paper presents the system level requirements for a buck converter and other blocks in a dyn...
