数字与模拟电路设计技巧
数字与模拟电路设计技巧<BR>IC与LSI的功能大幅提升使得高压电路与电力电路除外，几乎所有的电路都是由半导体组件所构成，虽然半导体组件高速、高频化时会有EMI的困扰，不过为了充分发挥半导体组件应有的性能，电路板设计与封装技术仍具有决定性的影响。 模拟与数字技术的融合<BR>由于IC与LSI半导体本身的高速化，同时为了使机器达到正常动作的目的，因此技术上的跨越竞争越来越激烈。虽然构成系统的电路未必

基于UC3854A控制的PFC中分岔现象仿真研究
<DD> 为深入了解基于UC3854A控制的PFC变换器中的动力学特性，研究系统参数变化对变换器中分岔现象的影响，在建立Boost PFC变换器双闭环数学模型的基础上，用Matlab软件对变换器中慢时标分岔及混沌等不稳定现象进行了仿真。在对PFC变换器中慢时标分岔现象仿真的基础上，分析了系统参数变化对分岔点的影响，并进行了仿真验证。仿真结果清晰地显示了输入整流电压的幅值变化
基于DSP的永磁同步电机新型矢量控制技术研究.rar
应用于电动汽车驱动领域的永磁同步电机交流驱动系统是由永磁同步电机、电力电子技术和控制技术相结合而形成的新型交流驱动系统。因其具有良好的运行性能而成为当代电气传动领域研究的热点之一。 永磁同步电机是一个多变量、非线性、高强耦合的系统，其输出转矩与定子电流不成正比，而是复杂的函数关系，因此要得到好的控制性能，需要进行磁场解耦。矢量变换控制技术正好适用于永磁同步电机的这种特点。 本文在数字电机控制专用D
