Inductance and capacitance filter circuit
如上圖所示的電路時在整流電路與濾波電路之間串聯一個電感線圈，構成了電感、電容濾波電路，此電路能進一步減小輸出電壓uouo的脈動程度。當通過電感線圈的電流變化時，電感線圈則產生感應電動勢阻礙電流變化，也可理解為當電流減小時，電感線圈將儲存的能量釋放給負載，這樣使負載電流和負載電壓脈動程度減小。電感量越大，濾波效果越好。
As shown in the above figure, an inductance coil is connected in series between the rectifier circuit and the filter circuit to form the inductance and capacitance filter circuit, which can further reduce the fluctuation of the output voltage UOUO. When the current through the inductance coil changes, the induction electromotive force will be generated by the inductance coil to prevent the current change. It can also be understood that when the current decreases, the inductance coil will release the stored energy to the load, so that the load current and load voltage pulsation will be reduced. The larger the inductance, the better the filtering effect.
一般濾波線圈採用鐵心電感線圈，成本高、體積大，又比較笨重。所以電感、電容濾波適用於負載電流較大（即RLRL小），要求輸出電壓脈動較小的場合。YCB YCBP YCBPG扁電纜
Generally, the filter coil adopts iron core inductance coil, which has high cost, large volume and heavy weight. Therefore, inductive and capacitive filtering is suitable for the occasion of large load current (i.e. small rlrl) and small output voltage ripple.
