摘  要
 二次電源作為負載的能量供應裝置，在電路系統中起著非常重要的作用。尤其在我國，交流電網的電壓波動較大、干擾較多，二次電源已成為許多電子設備不可缺少的供電裝置。安全可靠、技術性能符合負載要求的電源，可使負載的功能得以充分發揮，否則，可能使負載的技術指標降低，甚至會損壞負載。因此，作為二次供電電源，交流穩壓電源己廣泛用于工業生產、軍事設施、醫療儀器及日常生活等各個方面，成為電子設備和機電設備可靠運行的基礎設備，為了延長用電設備的使用壽命，降低工廠的經濟損失，應保證其供電電壓的穩定。尤其在工業現場環境下，電網品質差，電網波形畸變嚴重。因此，研制一種高效可靠的交流穩壓電源作為負載的二次供電電源十分必要。本課題是利用單片機（AT89S52）控制技術控制開關器件的通斷，并按補償電壓的大小接入或切除某個補償變壓器，進行快速適時調節，保證了了供電電壓的穩定。該設計主要分為以下六個模塊：補償單元、調節單元、單片機控制單元、半波整流單元、A/D轉換單元、保護單元及報警單元。
 
 關鍵詞：補償式、交流穩壓器、單片機、A/D轉換

Abstract
 secondary power sources took tthe energy supply device of the load, is playing a very important role in the circuitry.Especially in our country, in alternate current network the voltage is more fluctuations, and more interference, secondary power sources have become indispensable power supply device in many electronic devices. Safe and reliable, with technical performance requirements of the power load, the load can be fully functional play, or else possibly causes the load the technical specification to reduce, even can damage the load. Therefore, as a secondary power supply,AC voltage-stabilized source has been  widely uses in the industrial production, the military installation, the medical instrument and the daily life and so on each aspect, becomes the electronic installation and the electromechanical device reliable movement foundation equipment, in order to lengthen the service life of  current collector, reduces the economic loss of  factory . should guarantee its power line voltage the stability. Especially in the industrial field environment,the electrical network quality is especially bad, the electrical network waveform distortion is serious. Therefore,it is very necessary to develop a highly efficient and reliable ac voltage-stabilized source as the second power supply of load.This topic is use single—chip microcomputer (AT89S52) to control switch component the make-and-break, and according to the size of the compensation voltage access or the removal of a transformer compensation for quick timely adjust, guaranteed a supply voltage stability. The main design is divided into the following six major modules : Compensation module, regulatory module, single—chip microcomputer control module, voltage detection module, A/D conversion module, protection module and alarm module.
