本文提出具定流控制與無燈管保護電路之螢光燈自激式全橋電子安定器的電路，用來解決自激式全橋電子安定器兩個先天上既有的問題。
由於自激式全橋電子安定器的燈管電流受輸入電壓變動而改變，造成螢光燈的亮度隨之變動。此外，當燈管負載移除或損壞時，將導致電子安定器燒毀。因此，本文提出定電流控制與無燈管保護之電路，藉此穩定燈管亮度及保護自激式全橋電子安定器。
本文將設計及完成一個38W的具定流控制與無燈管保護電路之螢光燈自激式全橋電子安定器，俾以驗證本文所提出之電子安定器的性能與可行性。

This thesis presents the self-oscillating full-bridge electronic ballast with constant-lamp-current control and no-lamp-protection circuit for use in fluorescent lamps. The proposed ballast resolves the two inherent issues related to the self-oscillating full-bridge electronic ballast. The first of these inherent problems is that the lamp current varies according to the input AC voltage to causes different levels of brightness of the lamp. Secondly, once the lamp load is removed or broken, the ballast continuously attempts to generate an abnormally excessive voltages and currents, which results in failure of the components in the ballast.
Integrating the constant-lamp-current control and the proposed no-lamp-protection circuit into the self-oscillating full-bridge electronic ballast resolves the ballast’s issues of unstable brightness and failure of the components during no-lamp conditions.
Finally, a 38W self-oscillating full-bridge electronic ballast with constant-lamp-current control and no-lamp-protection circuit for use in fluorescent lamps is designed and implemented to demonstrate the feasibility and performance of the proposed electronic ballast.
