Providing power for the Pentium® microprocessor family isnot a trivial task by any means. In an effort to simplify thistask we have developed a new switching regulator controlcircuit and a new linear regulator to address the needs ofthese processors. Considerable time has been spent developingan optimized decoupling network. Here are severalcircuits using the new LTC®1266 synchronous buck regulatorcontrol chip and the LT®1584 linear regulator toprovide power for Pentium processors and Pentium VREprocessors. The Pentium processor has a supply requirementof 3.3V ±5%. The Pentium VRE processor requires3.500V ±100mV.

基于硅光伏電池單元的物理模型和光伏組件及光伏陣列的串并聯結構,采用PSpice構建了小型硅光伏陣列的仿真模型,并利用該模型對光伏直流buck變換電路的開環和恒壓控制閉環特性進行了仿真研究.仿真結果與實驗數據對比表明,此模型能夠在較高的近似程度上方便地模擬實際光伏電池的行為特性,將PSpice軟件用于光伏發電系統的仿真是可行的.

The FPGA can realize a more optimized Digital controller in DC/DC Converters when compare to DSPs. In this paper, based on the FPGA platform, The theoretical analysis, characteristics, simulation and design consideration are given. The methods to implement the digital DC/DC Converters have been researched. The function module, state machine of digital DC/DC controller and high resolution DPWM with Sigma- Delta dither has been introduced. They are verified by experiments on a 20 W, 300 KHz non-isolated synchronous buck converters.
