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.

基于硅光伏电池单元的物理模型和光伏组件及光伏阵列的串并联结构,采用PSpice构建了小型硅光伏阵列的仿真模型,并利用该模型对光伏直流BUCk变换电路的开环和恒压控制闭环特性进行了仿真研究.仿真结果与实验数据对比表明,此模型能够在较高的近似程度上方便地模拟实际光伏电池的行为特性,将PSpice软件用于光伏发电系统的仿真是可行的.

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.
