Proteus 仿真软件在单片机设计中的应用(摘 要 单片机应用技术所涉及到的实验实践环节比较多，而且硬件投入比较大。在具体的工程实践中，如果因为方案有误而进 行相应的开发设计，会浪费较多的时间和经费。Proteus 仿真软件很好的解决了这些问题，他可以象Protel 一样画好硬件原理图 与KEIL 编程软件结合进行编程仿真调试。)

站长，不好意思... 我将我的信箱写错了... 写成：ddccbbaa@sina.cn了... 前面我传输的文件是：“qibaoshanplan.doc”这个文件，并且，是我的一篇论文底稿，我还想您提出了建议“增加创意文案的文件上载”的类型。 我的名字叫：褚江。 这篇文建，我又重新上传了一下... 我会为我的错误买单，马上我再传一篇论文，是我在《云计算》的课堂上书写的... 希望站长，能够将弟我，重新添加到PUDN的大家庭中。(Master, I am sorry ... I was wrong ... in my mailbox written: ddccbbaa@sina.cn up ... in front of my files transferred are: " qibaoshanplan.doc" the file, and it is my a thesis papers, I would like your recommendations " to increase creative copy of the file upload" type. My name is: Chu River. This CCA, I re-uploaded it ... I' ll pay for my mistake, I immediately re-transmission of a thesis, I was in the " cloud computing" classroom writing ... hope that the station can be The brother I re-added to PUDN the family.)

In higher power applications to utilize the full line power and reduce line current harmonics PFC Pre-regulators are generally required. In these high power applications interleaving PFC stages can reduce inductor volume and reduce input and output capacitor ripple current. This results in smaller overall magnetic volume and filter capacitor volume increasing the converters overall power density. This is made possible through distributing the power over two interleaved boost converters and the inductor ripple current cancellation that occurs with interleaving, reference [5]. This application note will review the design of a 300W two-phase interleaved power factor corrected (PFC) pre-regulator. T

本压缩包 包含 任务书、论文以及答辩ppt，虽说是课程设计，但是按照毕业设计书写，内容充实 本次课程设计主要是对象湖变的电网进行保护整定，对d1至d6共6个地方进行了最大方式与最小方式运行情况下的短路电流计算。计算完短路电流后，对L1至L5共5条线路进行电流保护整定。但是由于线路较短，线路阻抗较小。经计算后均不适合三段式电流保护。所以采取了纵联差动保护作为主保护，定时限过电流保护作为后备保护。对于变压器，采用纵联差动保护与气体保护共同作为主保护，过负荷保护作为后备保护。(The curriculum design is the object variable grid lake protection setting of D1 to D6, 6 places for the maximum and minimum operation mode under the condition of short-circuit current calculation. Calculation of short-circuit current after the end, L1 to L5 a total of 5 lines of current protection setting. But because of shorter lines, line impedance is small. The calculations are not suitable for three phase current protection. So take a longitudinal differential protection as the main protection, timing and limiting current protection as a back-up protection. For transformers, using longitudinal differential protection and gas protection as the main protection, overload protection as a back-up protection.)
