Ukushintsha umgomo wokwakhiwa kokunikezwa kwamandla + ukuhlaziywa komdwebo wesifunda (Ingxenye 2)
(A) Umgomo wokuqamba wokunikezwa kwamandla okushintsha 1.1 Isekethi yesihlungi esiwumugqa, isekethe yokucindezela yamanje, isekethe yesilungisi. Umsebenzi: Guqula igridi yokufaka yamandla kagesi we-AC ibe amandla okufaka we-DC wokushintshwa kwamandla okuhlangabezana nezimfuneko. 1....Funda kabanzi -
Yiziphi izinto eziyinhloko ezidala umsindo ongajwayelekile kuma-high-frequency transformers?
Ama-high-frequency transformers ngezinye izikhathi enza umsindo ngesikhathi sokusebenza, futhi esinye sezizathu zalokhu ukupholisa. Ngenxa yokuthi ifeni idala umsindo, indlebe yomuntu izwela kakhulu le harmonic ye-broadband kunama-harmonics akhiqizwa imvamisa eyinhloko. Imvamisa ephezulu incike...Funda kabanzi -
Ukuqonda kanjani ukuthi ama-transformer afanelekile awagcini amandla, kepha ama-inductors angagcina amandla kagesi?
Okokuqala, mayelana nokuthi amandla angagcinwa yini, ake sibheke umehluko phakathi kwama-transformer afanelekile kanye nama-transformer asebenzayo: 1. Incazelo kanye nezici zama-transformer afanelekayo Izindlela zokudweba ezivamile zama-transformer afanelekile I-transformer ekahle iyisekethe efanelekile...Funda kabanzi -
Umgomo wokusebenza wokushintsha ukunikezwa kwamandla + ukuhlaziya umdwebo wesifunda
1. Uhlolojikelele Lokushintshanisa Ukunikezwa Amandla Ukushintsha ukuphakelwa kwamandla kuyidivayisi yokuguqula amandla kagesi eyimvamisa ephezulu, eyaziwa nangokuthi ukunikezwa kwamandla okushintsha noma isiguquli sokushintsha. Ishintsha i-voltage yokufaka ibe isignali ye-pulse high-frequency ngokusebenzisa ishubhu yokushintsha enesivinini esikhulu, bese iguqula...Funda kabanzi -
Ukuvunguza kwamandla aphansi ama-transformer emvamisa yezimboni
Izinhlobonhlobo zemishini yasendlini, ama-frequency transformer ezimbonini, kungakhathaliseki ukuthi aklama ukujika kwawo, noma ukulungisa i-transformer eshile, ahilelekile engxenyeni yokubala elula, izincwadi zefomula, nakuba ziqinile, kodwa ukusetshenziswa okungokoqobo kobunzima, hhayi kakhulu...Funda kabanzi -
Ingabe i-transformer eyehla izendlalelo ingaholela ekuqhumeni?
Enkambweni ye-transformer winding, ngenxa yezizathu ezihlukahlukene, kulula ukubangela ukuwela phansi kwesendlalelo. Ngakho-ke, izoholela ini isendlalelo se-transformer winding drop drop? Ingabe izoqhuma? Ngalesi sigameko, singakugwema kanjani? Esihlokweni esithi "Ulwazi lokuphepha lwe-transformer", siyazi ...Funda kabanzi -
Izintambo ezindizayo kuma-transformer
Izintambo ezindizayo, ama-windings ahola kusukela phezulu kwe-transformer, ngokuvamile afakwe ama-insulated futhi anemikhono. Abantu abaningi abakwazi ukuzibamba kodwa babe nombuzo: kungani i-transformer inezintambo endizayo? Okokuqala, izintambo ezindizayo ze-transformer design, ukuhlangabezana nezidingo zokuphepha. Genener...Funda kabanzi -
Kungani i-transformer idinga ukukhulelwa?
[I-impregnation] inqubo evamile ekukhiqizeni ama-high-frequency transformers. Kungani i-transformer idinga ukukhulelwa? Yiziphi izinyathelo zokuphepha zokukhulelwa? Namuhla, ake sikhulume ngezihloko ezihlobene. [I-impregnation] ibhekisela ekubekeni i-transformer kumafutha avikelayo (futhi calle...Funda kabanzi -
Izixazululo ze-LED ezihlukanisiwe nezingezodwa
Izixazululo ze-LED ezihlukanisiwe nezingezodwa ngayinye inezici zayo kanye nezimo zohlelo lokusebenza kubuchwepheshe bokukhanyisa kwe-LED.Nansi ukuhlaziywa okuningiliziwe kwazo zombili izinketho: 1. Isixazululo se-LED Esodwa A. Incazelo kanye nezici Ukuhlukaniswa kukagesi: Isici esiyinhloko se-t...Funda kabanzi -
Inductor
Isigaba se-Inductor: 1. Ukuhlelwa ngesakhiwo: Isifaki somoya esiwumgogodla: Awukho umongo kazibuthe, ulinyazwe ngocingo kuphela. Ifanele izinhlelo zokusebenza zefrikhwensi ephezulu. I-Iron core inductor: Sebenzisa izinto ze-ferromagnetic njengomongo kazibuthe, njenge-ferrite, i-iron powder, njll. Lolu hlobo lwe-inductor luvame ukusetshenziswa e...Funda kabanzi -
Yini i-inductor?
1. Iyini i-inductor: I-inductor iyingxenye ye-elekthronikhi egcina amandla kazibuthe. Ilinyazwe ngocingo olulodwa noma ngaphezulu, ngokuvamile ngendlela yekhoyili. Lapho i-current idlula ku-inductor, ikhiqiza insimu kazibuthe, ngaleyo ndlela igcine amandla. Isici esiyinhloko se...Funda kabanzi
