Umgomo we-inductor ogcina amandla kagesi
Umsebenzi oyinhloko we-inductance ukugcina i-alternating current (ukugcina amandla kagesi ngendlela yamagnetic field), kodwa ayikwazi ukugcina i-direct current (i-direct current ingadlula ikhoyili ye-inductor ngaphandle kwesithiyo). Umsebenzi oyinhloko we-capacitance ukugcina i-direct current (ukugcina...Funda kabanzi -
Isibani se-LED asisebenzi kodwa sinamathiphu okulungisa amandla
Empilweni yesimanje, siya ngokuya sisebenzisa izibani ze-LED njengokukhanyisa okuyinhloko. Awonga amandla, ahlala isikhathi eside, futhi ayihambisani nemvelo, futhi asetshenziswa kakhulu ezindlini nasezindaweni zentengiso. Nokho, yini okufanele siyenze lapho izibani ze-LED zingasakhanyi? Ungakhathazeki! T...Funda kabanzi -
Ungawuthola kanjani umnyombo we-high frequency transformer?
Ungawuthola kanjani umnyombo we-high-frequency transformer? Abantu abathenga ingqikithi ye-high-frequency transformer besaba ukuthenga ingqikithi eyenziwe ngezinto ezisezingeni eliphansi. Ngakho kufanele kutholwe kanjani umnyombo? Lokhu kudinga ukuqonda ezinye izindlela zokuthola umnyombo we...Funda kabanzi -
Izinga lokushisa le-Curie le-transformer core
“Esikhathini esithile emuva, othile wabuza ukuthi umazibuthe unezinga lokumelana nezinga lokushisa. Futhi othile waphendula kanje: 'Ibanga lokumelana nezinga lokushisa elezinto zokuvikela ukushisa. I-magnetic core ayibhekwa njengento evikelayo, ngakho-ke ayinawo ulaka oluthile...Funda kabanzi -
Incazelo enemininingwane yokuhluleka kwe-transformer high voltage okubangelwa uhlaka lwamathambo
Ama-high-frequency transformers angenye yezingxenye ze-elekthronikhi ezibalulekile zemikhiqizo ye-elekthronikhi. Uma kwenzeka okungavamile ngesikhathi sokusetshenziswa, imikhiqizo ye-elekthronikhi izoqhuma, futhi ezimeni ezinzima, izosongela ukuphila komuntu. Ngokusho kwemininingwane yokuhlola yama-high-frequency transformers, ukumelana...Funda kabanzi -
Izimpawu zama-cores of shapes ezehlukene
Izimo ezivamile eziyinhloko zihlanganisa i-can, i-RM, i-E, uhlobo lwe-E, i-PQ, i-EP, indandatho, njll. Izimo ezihlukene eziyinhloko zinezici ezihlukene: 1. Ingabe Uhlaka lwamathambo kanye nama-winding cishe kusongwe ngokuphelele yi-core, ngakho-ke umphumela wokuvikela we-EMI kuhle kakhulu; i-can design yenza ibize kakhulu kune-cor...Funda kabanzi -
Kuyini ukusebenza kwe-no-load/load of high-frequency transformer?
Phakathi kwemiqondo eyisisekelo yama-high-frequency transformers, kunesimo sokusebenza se-high-frequency transformers ebizwa ngokuthi akukho-load operation yama-transformers. Ukusebenza okungalayishwanga kwama-high-frequency transformers kusho ukuthi ukujikajika okuyinhloko kwe-transformer kuxhunywe kugesi kanye ne-s...Funda kabanzi -
Ngabe ama-inductor transformer anamandla aphezulu azoba umkhuba wokuthuthuka wesikhathi esizayo?
Ngokuthuthuka kwemakethe yamandla amasha, ama-inductor transformer athuthuka kancane kancane abheke kumafrikhwensi aphezulu, amandla kagesi aphezulu kanye namandla aphezulu. Ngabe ama-inductor transformer anamandla aphezulu azoba umkhuba wokuthuthuka wesikhathi esizayo futhi abone ukukhiqizwa okuzenzakalelayo okukhulu? Ngokusho kwe-National dual c...Funda kabanzi -
Asungulwa kanjani ama-LED?
Ukusungulwa kwama-LED (light emitting diode) kwakuyinqubo enezigaba eziningi ehlanganisa iminikelo yososayensi abaningi. Nazi ezinye izikhathi ezibalulekile zomlando ekusungulweni kwama-LED: Ithiyori yakuqala kanye nokuhlola: 1907: Usosayensi waseBrithani u-HJ Round waqala ukubona ukuthi i-semiconductor mate...Funda kabanzi -
Kungani i-LED ingakhipha ukukhanya?
I-diode ekhipha ukukhanya i-diode ekhethekile. Njengama-diode ajwayelekile, ama-diode akhipha ukukhanya akhiwe ngama-semiconductor chips. Lezi zinto ezisetshenziswayo ze-semiconductor zifakwa ngaphambili noma zifakwe i-doped ukukhiqiza izakhiwo zika-p kanye no-n. Njengamanye ama-diode, i-current ku-diode ekhipha ukukhanya ingageleza kalula isuka ku-p...Funda kabanzi -
Iqhaza lama-electronic transformer kubuchwepheshe bokuphakela amandla
Ama-electronic transformer nama-semiconductor switching devices, ama-semiconductor rectifier, ama-capacitor ndawonye, aziwa njengezingxenye ezine eziyinhloko kudivayisi yokuphakela amandla. Ngokusho kwendima kudivayisi yokuphakelwa kwamandla, ama-electronic transformers angahlukaniswa abe: (1) Ukunikezwa kwamandla...Funda kabanzi -
Isiguquli sebhodi lesifunda saturation kazibuthe
Kuyini ukugcwaliswa kazibuthe kwe-transformer? Lapho inkambu kazibuthe yangaphandle iqhubeka iba namandla kodwa ukuguquguquka kazibuthe ku-transformer kungaguquki ngempela, kusho ukuthi isiguquli sifinyelele endaweni yokugcwala kazibuthe.
