摘 要:針對許多濾波器設(shè)計(jì)時只注重諧波濾除,卻忽略逆變器效率的問題,從調(diào)整無功功率的角度,提出一種LC 濾波器的設(shè)計(jì)方法。該方法既滿足了抑制諧波含量的要求,又提高了電源利用率。通過對不間斷電源(UPS) 阻性、感性、容性負(fù)載進(jìn)行分析,驗(yàn)證了該方法的有效性。
關(guān)鍵詞:濾波器;無功功率;不間斷電源;電源利用率

Abstract: Aiming at the problem of ignoring inverter’s efficiency when harmonic smoothing is paid attention to in the design of many filters, this paper proposed a kind of LC filter design method from the corner of adjusting reactive power. This method not only met the requirement of suppressing harmonic content, but also raised power supply utilance. Resistive, inductive and capacitive loads of uninterruptible power source (UPS) were carried out analysis to verify the validity of the method.
          Key words: filter; reactive power; uninterruptible power source; power supply utilance
