现有主流LED驱动电路采用在电路输出端加大容量电解电容来达到储能和恒流的目的，这将导致整体电路因为电解电容寿命不足而使整体电路寿命减少。本文提出了一种基于反激式开关电路的新型LED驱动电路，双副边电感电路在有效的解决LED频闪问题的同时也降低了电路对电容容量的需求。电路可行性已经由仿真实验的结果得到验证。
現有主流LED驅動電路採用在電路輸齣耑加大容量電解電容來達到儲能和恆流的目的，這將導緻整體電路因為電解電容壽命不足而使整體電路壽命減少。本文提齣瞭一種基于反激式開關電路的新型LED驅動電路，雙副邊電感電路在有效的解決LED頻閃問題的同時也降低瞭電路對電容容量的需求。電路可行性已經由倣真實驗的結果得到驗證。

In order to achieve the purpose of store charge and constant current, electrolytic capacitor always be used in LED driver, that would reduce the whole circuit's life. So propose an innovative LED driver based on flyback converter, double secondary winding circuit successfully solve the problem of LED flick and reduce the demand of capacitance. The feasibility of the propose LED driver has been verified by experiments.
