Based on the periodicity of active current and the DC-bus voltage variation characteristic with the power flowing between AC source and DC-side capacitor of APF,this paper presents a new linear cycle discrete control method for DC-bus voltage.

- 針對有源濾波器電流諧波分量檢測運算復雜,且在負荷電流變化時(shí)出現電源電流畸變現象,從直流側電容電壓與交、直流側功率傳遞的關(guān)系出發(fā),并結合有功電流的周期性特點(diǎn),提出了基于直流側電容電壓周期離散控制的新型有源濾波器控制方法。
