N'ime inverter na converter ọdịnala, capacitors bọs bụ capacitors electrolytic, mana n'ime ndị ọhụrụ, a na-ahọrọ capacitors fim, kedu uru nke capacitors fim ma e jiri ya tụnyere capacitors electrolytic?

Ugbu a, ọtụtụ ndị na-agbanwe agbanwe etiti na eriri na-ahọrọ capacitors fim maka ihe ndị a:

(1) Ndị na-etinye ihe nkiri nwere ike inweta ike iguzogide voltaji dị elu karịa ndị na-etinye ihe eletriki. Voltaji aluminom nwere ike iguzogide voltaji dị ala, ruo 450 V. Iji nweta ọkwa iguzogide voltaji dị elu, a na-ejikarị ha eme ihe n'usoro, a ga-atụlekwa nsogbu nke nha nha voltaji n'usoro njikọ usoro. N'ụzọ dị iche, ndị na-etinye ihe nkiri nwere ike iru 20KV, yabụ ọ dịghị mkpa ịtụle njikọ usoro na ngwa inverter voltaji dị ọkara na elu, n'ezie, ọ dịghị mkpa ịtụle nsogbu njikọ dịka nha nha voltaji na ọnụ ahịa na ike mmadụ kwekọrọ.

(2) Ihe mkpuchi ihe nkiri nwere ike iguzogide okpomọkụ karịa ihe mkpuchi electrolytic.

(3) Ogologo ndụ nke ihe nkiri capacitor dị ogologo karịa nke electrolytic capacitor. N'ozuzu, ogologo ndụ nke electrolytic capacitor bụ 2,000H, mana ogologo ndụ nke CRE film capacitor bụ 100,000H.

(4) ESR pere mpe nke ukwuu. ESR nke ihe nkiri capacitor na-adịkarị ala nke ukwuu, n'ozuzu ya na-erughị 1mΩ, parasitic inductance dịkwa obere nke ukwuu, naanị iri nH ole na ole, nke a na-enweghị atụ site na aluminum electrolytic capacitors. ESR dị oke ala na-ebelata nrụgide voltaji na tube switching, nke bara uru maka ntụkwasị obi na nkwụsi ike nke tube switching.

(5) Ike siri ike karịa nke na-eguzogide ọkụ eletrik. Ike nrụgide nke ihe nkiri metalized capacitors nwere ike ịbụ ugboro iri ruo ọtụtụ iri na abụọ nke ike nrụgide nke aluminom electrolytic capacitors nke nwere otu ikike ahụ. Iji nweta ike nrụgide dị elu, ike nrụgide electrolytic aluminum na-ejikarị ikike ka ukwuu iji mezuo ihe achọrọ, ebe ikike ka ukwuu bụ mmefu ego na oghere nrụnye na-enweghị isi.
