Ihe nkiri Capacitors VS Electrolytic Capacitors na Inverters na Ntụgharị

Na inverter na ntụgharị ọdịnala, ndị na-eme ụgbọ ala bụ ndị na-eme ihe ọkụ eletrik, ma n'ime ndị ọhụrụ, a na-ahọrọ ndị na-emepụta ihe nkiri, kedu uru ndị na-eme ihe nkiri na-eme ka e jiri ya tụnyere electrolytic capacitors?

 

Ka ọ dị ugbu a, ọtụtụ ndị na-eme ka etiti na eriri inverters na-ahọrọ capacitors ihe nkiri maka ihe ndị a:

 

(1) Ihe nkiri capacitors nwere ike nweta elu voltaji na-eguzogide karịa electrolytic capacitors.The gosiri voltaji nke aluminum electrolytic capacitors dị ala, ruo 450 V. Iji nweta elu voltaji na-eguzogide larịị, ha na-emekarị mkpa ka a na-eji na usoro, na nsogbu nke voltaji equalization ga-atụle na usoro nke usoro njikọ.N'ụzọ dị iche, ihe nkiri capacitors nwere ike iru ruo 20KV, n'ihi ya, ọ dịghị mkpa na-atụle usoro njikọ na ọkara na elu voltaji inverter ngwa, na N'ezie, ọ dịghị mkpa na-atụle njikọ nsogbu dị ka voltaji equalization na kwekọrọ ekwekọ na-eri na. ikike mmadụ.

 

(2) Ihe nkiri capacitors nwere elu okpomọkụ nguzogide karịa electrolytic capacitors.

 

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

 

(4) ESR dị obere karịa.The ESR nke ihe nkiri capacitor na-adịkarị ala, n'ozuzu n'okpuru 1mΩ, na parasitic inductance dịkwa nnọọ ala, nanị ole na ole iri nke nH, nke aluminom electrolytic capacitors na-enweghị atụ.ESR dị oke ala na-ebelata nrụgide voltaji na tube ntụgharị, nke bara uru maka ntụkwasị obi na nkwụsi ike nke tube ntụgharị.

 

(5) Stronger ripple ugbu a resistance.The ripple ugbu a iguzogide metalized film capacitors nwere ike iri na ọtụtụ iri na abuo ugboro nke gosiri ripple ugbu a nke aluminum electrolytic capacitors nke otu ikike.Iji nweta nguzogide dị elu ugbu a, aluminom electrolytic capacitors na-ejikarị ikike buru ibu iji mezuo ihe ndị a chọrọ, ebe ikike buru ibu bụ ihe efu na-enweghị isi nke ọnụ ahịa na oghere ntinye.
