半导体三极管除了构成放大器和作开关元件使用外，还能够做成一些可独立使用的两端或三端器件。文中介绍了三极管的几种特殊用途-Posed apart from the semiconductor transistor amplifiers and switching elements for use, but also be able to make some available for independent use of both ends, or three-terminal device. In this paper, several special-purpose transistor

此社会实践报告绝对是本人原创，当然了其中一些数据是在网络上找的！-social practice this report is absolutely original, I, of course, some of them are data on the network to find!

此程序在于，调用ISE中自带的DDS__IP，来产生单正弦信号，该程序已通过布线后仿真实现-The program focus on that it utilize the DDS core embedded in the ISE to generate the sigle sinusoid signal and this program have acess to the posted simulation!

驱动升压转换他关键原理是电感的倾向抗蚀电流变化通过创建和销毁的磁场。在升压转换器中，输出电压总是比输入电压高。升压功率级的示意图示于图1。（a）当所述开关被关闭时，电流通过产生的磁场流过电感器的顺时针方向和电感器存储一定的能量。电感器的左侧的极性是正的。（b）当所述开关打开时，电流将被减小的阻抗较高。先前产生的磁场会被破坏，保持朝向负载的电流。因此，极性将被反转（意味着电感器的左侧现在将是负的）。其结果是两个源将在串联导致更高的电压，以将电容器通过二极管D充电
