基于并聯(lián)諧振的高壓直流電源研究基于并聯(lián)諧振的高壓直流電源研究

摘要：本文針對(duì)現(xiàn)有高壓直流電源在電力等領(lǐng)域應(yīng)用中存在的缺陷，提出了一種基于并聯(lián)諧振的高壓直流電源方案。該方案采用并聯(lián)諧振電路進(jìn)行諧振運(yùn)行，有效地降低了諧振電路的諧振頻率，提高了輸出效率，同時(shí)減小了諧振電路對(duì)系統(tǒng)中其他組件的干擾。在理論模型的基礎(chǔ)上，本文設(shè)計(jì)并構(gòu)建了一個(gè)基于并聯(lián)諧振的高壓直流電源系統(tǒng)，并通過實(shí)驗(yàn)驗(yàn)證了該系統(tǒng)的穩(wěn)定性和可靠性。實(shí)驗(yàn)結(jié)果表明，該系統(tǒng)的輸出效率可以達(dá)到93%以上，遠(yuǎn)高于傳統(tǒng)高壓直流電源的效率，并且在負(fù)載變化下具有很好的響應(yīng)時(shí)間和穩(wěn)定性，可以滿足實(shí)際應(yīng)用需求。
