An AC constant current power supply design based on linearity power amplifier

Abstract

交流恒流源作为稳定电源的分支有广泛用途,其作为一项技术在电源的研究领域中有很重要的意义。其发展与科技的进步息息相关,在各个国家特别是发达国家的国民经济中占有十分重要的地位。近年来我国检测技术有了较大的提高,但同发达国家的电网检测技术相比,差距仍然很大,存在参数检测精度不高、抗干扰性较差,实时性比较差、电路设计复杂等缺点。针对这些问题,本课题建立了一个以AT89C51单片机为控制核心的恒流源控制系统,该系统具有速度快、精度高、实用性强、电路模块化等特点。 本课题已经顺利完成以下几部分内容: 1硬件控制系统:这部分是整个恒流源系统的核心部分,利用突破传统并优化了的电路结构,基于AT89C51的...The point to constant current power supply which is a special technology that integrates several subjects such as mechanics, electronics and control knowledge. Its development is closely relationship with progresses of other science and technology subjects. it has important status in the multitudinous country specially in the developed country. In recent years, manufacture technology of our countr...学位:工学硕士院系专业:物理与机电工程学院机电工程系_精密仪器及机械学号:2005130172
