140V可调稳压电源的设计(论文10400字)
摘  要
一般来说负载或者电子器件所需要并且稳定的直流电压/流是直流稳压电源提供的。对于电子设备或者控制系统等电子器件的功能来说，会对其造成直接影响的因素很多时候主要是稳压电源的性能高低。线性稳压电源是直流稳压电源的一种类型，并且线性稳压电源中的线性集成稳压器在近些年来发展很快，其中应用较为广泛的是小功率的三端可调式稳压器。如LM317集成稳压器就是目前使用较为广泛的一款集成稳压器。
本文将详细的介绍以LM317集成稳压器为基础的140V可调稳压电源的设计，阐述设计140V可调稳压电源的背景、目的和意义，并从基础开始一一介绍设计的思路和选材的原理，对140V可调稳压电源的安装、焊接和调试也进行了详细的说明。

 The design of 140V adjustable voltage stabilizing power supply
Abstract
Generally speaking, the DC voltage / current required and stable by load or electronic devices is provided by DC voltage stabilizing power supply. For the functions of electronic devices such as electronic equipment or control system, the factors that will directly affect it are often the performance level of voltage stabilizing power supply. Linear voltage stabilizer is a type of DC voltage stabilizer, and the linear integrated  regulator in linear voltage stabilizer has developed rapidly in recent years, among which the three-terminal adjustable voltage regulator with low power is widely used. Such as LM317 integrated voltage regulator ,it is an integrated voltage regulator which is widely used at present. [资料来源：Doc163.com]
