Chiyambi cha mfundo ya high frequency thiransifoma

Monga dzina limatanthawuzira, high-frequency transformer ndi chida chamagetsi chamagetsi chomwe chimasintha magetsi.Ndi chipangizo chomwe chimagwiritsa ntchito lamulo la Faraday la electromagnetic induction kuti lisinthe magetsi a AC, makamaka opangidwa ndi coil yoyamba, ferrite.pachimake, koyilo yachiwiri, etc. Ikhoza kuzindikira kutembenuka kofananira kwa athandizira ndi linanena bungwe panopa, voteji ndi impedance, komanso kudzipatula thupi la pulayimale mlingo.Malinga ndi ma voliyumu osiyanasiyana oyambira, imatha kugawidwa kukhala chosinthira chotsika kwambiri, chosinthira chokwera kwambiri komanso chosinthira chapakatikati.

Ma frequency amagetsi omwe amagwiritsidwa ntchito pamoyo wathu watsiku ndi tsiku ndi 50Hz, yomwe imatchedwa low-frequency alternating current.Ngati transformer yothamanga kwambiri imagwira ntchito pafupipafupi, timayitcha kuti transfrequency high-frequency transformer low-frequency high-frequency transformer, yomwe imatchedwanso mphamvu yamagetsi yapamwamba kwambiri.Transformer yapamwamba kwambiri imakhala ndi voliyumu yayikulu komanso yotsika kwambiri.Chitsulo chachitsulo chimakhala ndi mapepala achitsulo otsekedwa ndi silicon, ndipo koyilo yoyamba imavulazidwa ndi waya wa enamelled.Mphamvu yamagetsi yoyambira imayenderana ndi kutembenuka kwawo.

Kuonjezera apo, ma transformer ena othamanga kwambiri amagwira ntchito m'makilomita mazana ambiri a kilohertz, ndipo transformer yothamanga kwambiri imakhala yothamanga kwambiri.Ma transformer apamwamba nthawi zambiri amagwiritsa ntchito maginito cores m'malo mwa iron cores.Transformer yapamwamba imakhala ndi voliyumu yaying'ono, masinthidwe ochepa a koyilo yoyambira komanso kuchita bwino kwambiri.

Ma frequency ogwirira ntchito a transformer yothamanga kwambiri nthawi zambiri amakhala makumi mpaka mazana a kilohertz.High frequency transformer imatenga maginito pachimake, ndipo chigawo chachikulu cha maginito pachimake ndi manganese zinc ferrite.Nkhaniyi ili ndi eddy yapano yotsika, yotsika kwambiri komanso yogwira ntchito kwambiri pama frequency apamwamba.Mafupipafupi otsika pafupipafupi a transformer yapamwamba kwambiri ndi 50Hz.High frequency thiransifoma pachimake ndi mtundu wa zofewa zitsulo maginito zakuthupi.Chitsulo chochepa cha silicon chikhoza kuchepetsa kutayika kwamakono kwa eddy, koma kutayika kumakhala kwakukulu kuposa kwapakati pamagetsi othamanga kwambiri.

Transfrequency yotsika kwambiri yokhala ndi mphamvu yotulutsa yomweyi ndi yaying'ono kwambiri kuposa yotsika kwambiri, ndipo mphamvu yake yotentha imakhala yochepa.Chifukwa chake pakali pano, ma adapter ambiri amagetsi ogula ndi zinthu zama network akusintha magetsi, ndipo chosinthira chamkati chapamwamba kwambiri ndichofunikira kwambiri pakusinthira magetsi.Mfundo yofunikira ndikusinthira zolowetsamo kuti zikhale DC, kenako ndikuzisintha kukhala ma frequency apamwamba kudzera pa triode kapena FET.Kupyolera mu kusintha kwa thiransifoma yapamwamba kwambiri, zotulukazo zimakonzedwanso, ndipo mbali zina zowongolera zimawonjezedwa kuti zikhazikitse magetsi a DC.

Mwachidule, kufanana pakati pa ma transfrequency high-frequency and low-frequency high-frequency transformers amachokera pa mfundo ya electromagnetic induction.Kusiyana kwake ndikuti ma frequency otsika komanso osinthira ma frequency apamwamba ndizitsulo zachitsulo zopangidwa ndi mapepala achitsulo a silicon, ndipo zosinthira pafupipafupi ndi zidutswa zonse zopangidwa ndi manganese zinc ferrite ndi zida zina.
