Iqondo lobushushu Ukuzinza kwedatha yeMagnetic ethambileyo yeRing inductor| PHILA

Yintoni ukuzinza kobushushu bedatha yemagnethi ethambileyo kwi- inductor toroidal ? Masilandele umsasazi ukuqonda umgaqo wokusebenza wemagnethi ethambileyo kwi-toroidal inductor.

Xa usenza i-toroidal inductor, ukukhethwa kwezinto eziphathekayo kwedatha yamagnetic ethambileyo kubaluleke kakhulu. Xa i-inductor isebenza, ubushushu buya kunyuka ngokuthe ngcembe, ngoko ke idatha yemagnethi ethambileyo kufuneka ibe nokuzinza okuhle kobushushu. Xa kufikwa ukumelana lobushushu eliphezulu, kufuneka sikhankanye intsimbi engundoqo data ring magnetic, le ring magnetic isetyenziselwa ukuncamathelisa umgubo magnetic kunye nokumila, iziko ilingana ezininzi izikhewu emoyeni encinane.

Ukukhetha i-Toroidal inductor

Kukho umsantsa womoya kwikhoyili ye-toroidal inductor kuba imagnethi yezinto ezincamathelayo ezifana neresin iphantse yafana naleyo yomoya. Oku kuthetha ukuba umgubo omncinci we-ferromagnetic oqulethwe kwidatha ye-ring magnetic, ngcono ukuzinza kobushushu be-inductor.

Kodwa ngokweendleko, ixabiso lentsimbi engundoqo yamagnetic liphezulu kunelo le-inductor engenanto. Izinto ze-Mn-Zn zinedatha ekhethekileyo yokuzinza okuphezulu, ukushisa okubanzi okanye ibhanti ebanzi. Ukuba imfuno ayichaphazeli kangako ukushisa, ukhetho lwe-CORE luxhomekeke kwimpembelelo yeqondo lokushisa kwi-inductor, kwaye i-inductance ayitshintshi kakhulu ngeqondo lokushisa, ebonisa ukuba ukuzinza kweqondo lokushisa kwe-CORE kulungile.

Kweli phepha, ukuzinza kobushushu bedatha yemagnethi ethambileyo ye-toroidal inductor kuxoxwa ngayo, kwaye ezinye iimbono malunga nokukhethwa kwedatha yemagnethi ethambileyo ibekwe phambili. Sinokukhetha idatha yemagnethi ethambileyo ngokweemfuno ezahlukeneyo.

Umgaqo wokusebenza we-toroidal inductor

Ukunikezelwa kwamandla okutshintsha ngokubanzi kukhetha i-half-bridge power conversion circuit, equkethe i-high-frequency transformer kunye ne-Triode njalo njalo. Ngexesha lokusebenza kwesekethe, i-transistor ijika enye emva kwenye, kwaye emva koko ivelise i-high-frequency pulse kunye ne-100KH rhoqo, kwaye emva koko iyancipha i-voltage ngokusebenzisa i-high-frequency transformer, kwaye emva koko ikhupha i-alternating current kunye ne-voltage ephantsi. emva kwe-Z. ixabiso elithile lombane liqinisekiswa ngumlinganiselo wokujika wekhoyili nganye ejikelezayo kwi-high-frequency transformer. Ngokuqhelekileyo, i-transformer emithathu isetyenzisiweyo, oko kukuthi, i-transformer eyintloko, i-drive transformer kunye ne-axiliary transformer. I-transformer nganye inomgangatho wayo kunye nomsebenzi, ngoko ke enye yazo iyimfuneko.

Oku ngasentla kukuqaliswa kokuzinza kweqondo lokushisa kwedatha yemagnethi ethambileyo ye-toroidal inductor. ukuba ufuna ukwazi ngakumbi malunga ne-toroidal inductor, nceda uzive ukhululekile ukuqhagamshelana nababoneleli ngengcebiso, uya kufumana uncedo lobuchwephesha.
