本文提出具功因校正之單級式電子安定器,其電路架構是由一升壓式功因修正網路與一直/交流轉換器所組成,主要使功因校正電感達到連續電流模式。因為傳統單級式電子安定器係操作於不連續電流模式,因而會有較高之電磁雜訊干擾、較大之電流應力及較大之切換與導通損失的缺點。所以本文提出一升壓式功因修正網路,使功因校正電感達到連續電流模式,來解決傳統單級式電子安定器的缺點。最後本文並實作與設計一額定功率為36W的具功因校正之單級式電子安器,來驗證此單級式電子安定器具有下述之優點:符合IEC 61000-3-2 Class C 國際電氣標準規範、具較小之傳導性電磁雜訊干擾、具較低之電流應力於開關及二極體上。
This thesis presents a continuous-current-mode (CCM) single-stage power factor correction (PFC) electronic ballast, which is a combination of a boost-type PFC network and a DC/AC inverter to allow CCM operation for the PFC inductor in the boost-type PFC network. Among the PFC techniques proposed in recent years, in general, the discontinuous-current-mode (DCM) single-stage PFC electronic ballasts have such drawbacks as high electromagnetic interference (EMI), high current stress, and high switching and conduction losses.
The PFC capacitor of the developed boost-type PFC network can help the PFC inductor to achieve CCM, thus shaping the input current of the proposed electronic ballast to achieve high power factor (PF).
Finally, a 36W rated power electronic ballast prototype circuit is designed and implemented. Experimental results verify the advantages of the proposed ballast; these include the following: the input current harmonics meet the IEC 61000-3-2 Class C Standard, and the ballast offers lower conducted EMI and lower current stress on switches and diodes.
