数控稳压电源的设计(论文6500字)
摘  要
在许多的领域（如数学、科学）直流稳压电源具有非常广泛的应用，同时也是电力电子的一种非常常见的设备。在传统的机械调节稳压电源与数字电位调节的稳压电源之间经过比较，我们的除了数字电位调节稳压电源的一些优点具体表现为：稳压能源能够从某一初始值在保持一定的速率下均匀增大或减小。如果使用传统的机械电位器调节的稳压电源就难以实现本实验的要求。为了配合以上要求，本实验采用X9511数字电位器作为调节电阻为的稳压电源，同时选用高精度OP07运算放大器放和LM317集成稳压器，设计并制作了一个数控直流可调稳压电源。

Design of NC Power Supply
Abstract
In many areas (such as mathematics, science) DC power supply has a very wide range of applications, but also a very common power electronic equipment. In this experiment, the use of digital potentiometer regulator of the regulated power supply instead of the traditional mechanical potentiometer regulator regulator power supply, because we need to regulate the power supply is uniform, the specific performance: From an initial value to maintain a certain rate of uniform increase or decrease. If the use of traditional mechanical potentiometer regulator power supply is difficult to meet the above requirements. In order to meet the above requirements, this experiment uses X9511 digital potentiometer as the regulator for the regulator power supply, while the choice of high-precision OP07 operational amplifier and LM317 integrated regulator, designed and produced a digital DC adjustable power supply
