论文开题报告基本要素

各部分撰写内容

论文标题应该简洁，且能让读者对论文所研究的主题一目了然。

摘要是对论文提纲的总结，通常不超过1或2页，摘要包含以下内容：

目录应该列出所有带有页码的标题和副标题， 副标题应缩进。

这部分应该从宏观的角度来解释研究背景，缩小研究问题的范围，适当列出相关的参考文献。

这一部分不只是你已经阅读过的相关文献的总结摘要，而是必须对其进行批判性评论，并能够将这些文献与你提出的研究联系起来。

这部分应该告诉读者你想在研究中发现什么。在这部分明确地陈述你的研究问题和假设。在大多数情况下，主要研究问题应该足够广泛，而次要研究问题和假设则更具体，每个问题都应该侧重于研究的某个方面。

你好，请问执行电路部分参数怎么改。麻烦您看下我的电路图。我们要求是前面有整流稳压，比较器。14 .18欠压过压，16正常。。绿色在正常电压时亮，两个红色不亮是对的。红色灯对应显示也是对的，但是绿色二极管一直都亮，无法在过压欠压时短路，不亮，如何调整参数

开关电源是利用现代电力电子技术，控制开关晶体管开通和关断的时间比率，维持稳定输出电压的一种电源，开关电源一般由脉冲宽度调制（PWM）控制IC和功率开关器件（如MOS-FET）等构成。简单的说：就是开关型直流稳压电源。开关电源把直流电源或交流电源通过它可以获得一个稳定的直流电压源。它具有效率高，输出电压稳定，交流纹波小，体积小和重量轻的许多优点。在设计中，以TL494作为PWM产生电路输出控制信号，控制开关管的导通状况，在半桥反激式输出的基础上实现了电源的多路输出。摘要1 绪论 引言 开关电源的分类 技术指标 开关电源的发展动向 2 开关电源原理及总体方案设计 开关电源基本原理 开关电源变换器设计 控制方式的选择 电压控制型 电流控制型 输出控制方式选型及设计 单端反激式输出 单端正激式输出 推挽式开关输出 降压式输出 升压式输出 3 具体电路设计 开关电源电路具体结构 输入电路的设计 控制电路设计 PWM工作原理 控制集成器TL494 PWM产生电路的设计 驱动电路设计 主电路的设计 主电路结构设计 高频变压器的设计 功率开关管的选择 缓冲保护电路的选择 输出电路设计 4 辅助电路的设计 防浪涌软启动电路 过压、欠压及过热保护电路 短路保护 辅助电源设计 5 总结致谢 参考文献
