  1. The author has finished the following several jobs in core of the centre : 1 ) the active compensation method based on bang - bang control was put forward to realize the wide range current transformer. the method converts the complex statement space to i / o description by the two - stage current transformer. with the compensation method, the accuracy of 0. 2 grade current transformer can be improved to less than the 0. 1 grade standard at 100 % rating when the primary side current is changed from 2 % to 120 % of the rating

    圍繞這一工作核心，作者完成了以下幾項工作： （ 1 ）以實現寬量程電流互感器為目標，提出了基於bang - bang控制的有源補償方法，採用雙級電流互感器，將復雜的狀態控制分量轉化為偏差控制，該方法結構簡單，調試方便，有源補償器輸出電流小，可以將0 . 2級的電流互感器經過補償后提高到一次電流從額定值的2變化到120時，測量誤差不超過一次電流額定值100時準確度為0 . 1級的測量標準。
  2. Five different structures are described : standard transformer coupling, parafeed, resistively loaded stage capacitively coupled to the output transformer, tube ( valve ) based constant current source load capacitively coupled to the output transformer, and solid state ( mos fet ) constant current source load capacitively coupled to the output transformer

    我們將討論五種不同的方式：標準變壓器耦合；旁饋耦合；電阻性負載電容性耦合至輸出變壓器；膽恆流源負載電容性耦合至輸出變壓器；以及晶體管恆流源負載電容性耦合至輸出變壓器。
  3. Two single - stage pfc converters with the negative feedback of engergy - storage capacotor voltage by transformer windings are analyzed. the two converters have similar performances, and they can be translated each other, which verified the translation rule. the analysis and simulation show that with the negative feedback of energy - storage capacitor voltage by transformer winding have good performances

    通過對兩種採用變壓器繞組實現負反饋的單級pfc變換器研究，結果顯示出它們的相近性，驗證了兩端模式和三端模式的轉換規則，同時也說明採用變壓器繞組實現負反饋的方式對抑制電容電壓有很好的效果，並對其進行了優化設計。
