1、浙江水利水電??茖W(xué)校畢業(yè)論文(設(shè)計)摘要隨著全球性不可再生能源的逐漸短缺,節(jié)能減排已成為我國乃至全世界工業(yè)發(fā)展所必需關(guān)注的問題。作為第三代綠色照明光源,金屬鹵化物燈由于其光效高、顯色性好、壽命長等特點在綠色照明工程中扮演了重要的角色。目前為金鹵燈配套的鎮(zhèn)流器仍然為傳統(tǒng)的電感式,這種鎮(zhèn)流器存在耗能高、效率低、體積大等問為開發(fā)研究的熱點。對研制的150W金鹵燈電子鎮(zhèn)流器樣機進行了測試,采集了其關(guān)鍵點的波形并進行分析。測試結(jié)果表明,所設(shè)計的金鹵燈電子鎮(zhèn)流器工作穩(wěn)定,輸出功率恒定,功率因數(shù)達到0.98以上,效率達到85%以上。
2、為抑制金鹵燈所特有的“聲共振現(xiàn)象”和解決電子鎮(zhèn)流器電磁兼容性等問題,本論文采用有源功率校正、恒功率控制和低頻方波驅(qū)動的三級式結(jié)構(gòu),設(shè)計了一款150W的金鹵燈電子鎮(zhèn)流器樣機。第一級實現(xiàn)有源功率校正。第二級實現(xiàn)恒功率控制。第三級實現(xiàn)全橋逆變和高壓點火功能。關(guān)鍵詞金屬鹵化物燈;電子鎮(zhèn)流器;聲共振;功率因數(shù);恒功率20浙江水利水電??茖W(xué)校畢業(yè)論文(設(shè)計)ABSTRACTWiththeglobalshortageofnon-renewableenergyresources,energysavingandconsumptionre
