I-POT3019 High Frequency Power Transformer

Ekuklanyweni kwe-high-frequency transformer, ukuvuza kwe-inductance kanye namandla okusabalaliswa kwe-transformer kufanele kuncishiswe, ngoba i-transformer ye-high-frequency ekushintsheni ukunikezwa kwamandla idlulisa amasignali e-high-frequency pulse square wave. Enqubweni yesikhashana yokudlulisa, ukuvuza kwe-iductance kanye namandla okusatshalaliswa kuzodala umfutho wamanje kanye nokuphakama kwe-voltage, kanye nokuzulazula okuphezulu, okuholela ekulahlekelweni okukhulu. Imvamisa, ukuvuza kwe-transformer kulawulwa njengo-1% ~ 3% we-inductance eyinhloko. Ukuvuza kokuvuza kwekhoyili eyinhloko yokuvuza kwe-transformer kubangelwa ukuhlangana okungaphelele kwe-flux kazibuthe phakathi kwekhoyili eyinhloko nekhoyili yesibili, phakathi kwezingqimba, naphakathi kokujika. I-Distributed capacitance-I-capacitance eyakhiwe phakathi kokujika kokujika kwe-transformer, phakathi kwezingqimba ezingaphezulu neziphansi zokujika okufanayo, phakathi kwama-winding ahlukene, naphakathi kwama-winding kanye nongqimba oluvikelayo kubizwa ngokuthi i-distributed capacitance. I-Primary winding-Ukujikajika okuyinhloko kufanele kubekwe ungqimba olungaphakathi impela, ukuze ubude bocingo olusetshenziswa ekujikeni ngakunye kwe-transformer primary winding bube bufushane kakhulu, futhi ucingo olusetshenziswa kuwo wonke ama-winding lungancishiswa, okunciphisa ngempumelelo amandla asabalalisiwe we-primary winding uqobo. I-Second Wining-Emuva kokuthi i-winding eyinhloko isilimele, kuyadingeka ukwengeza (3 ~ 5) izendlalelo zolayini wokufakelwa ngaphambi kokusonga ukujika kwesibili. Lokhu kunganciphisa amandla e-capacitor esabalalisiwe phakathi kokuvunguza okuyisisekelo kanye nokujikajika kwesibili, futhi kukhulise amandla okufaka phakathi kokuvunguza okuyinhloko kanye nokuvunguza kwesibili, okuhlangabezana nezidingo zokushisa nokumelana nomthamo. I-bias winding-ukuthi ukuchema okuchema kulimazekile phakathi kwesendlalelo sokuqala nesesibili noma ungqimba olungaphandle kakhulu kuhlobene nokuthi ukulungiswa kwamandla okushintshashintshayo kusekelwe ku-voltage yesibili noma i-voltage eyinhloko.
