1、數(shù)控電壓源設(shè)計報告ByKuangJunBinKuangJunBin：如您對本項目感興趣或者有任何疑問，歡迎與我一起探討：geforcefat@gmail.com。謝謝您的閱讀！-30-數(shù)控電壓源設(shè)計報告數(shù)控電壓源摘要：本作品采用AT89S52作為系統(tǒng)的控制核心，基于芯片MC34063、DAC0832、CD4511、LM358、ICL7107、LM311，良好地實現(xiàn)電壓轉(zhuǎn)換、電壓控制、實時顯示、電流擴大、同步電壓電流測量、過壓保護等主要功能。另外，采用1*4鍵盤進行參數(shù)設(shè)置，采用LED顯示參數(shù)設(shè)置，界面清晰，人機交互友好。本電壓源的特色是增加了13V過壓提示
2、和1.3A過流保護，以及采用ICL7107芯片實現(xiàn)對輸出電壓和輸出電流電流實時測量、顯示。關(guān)鍵詞：DC-DC轉(zhuǎn)換、AT89S52、數(shù)控、擴流、同步電壓電流測量、過壓保護ABSTRACT：ThisworkadoptstheAT89S52asthecontrol-centerofthesystem,basingonMC34063、DAC0832、CD4511、LM358、ICL7107、LM311,performingthemainfunctionsofvolttransfer,voltcontrol,displayin-phase,currentamplif
