Kev suav cov lem ntawm high-frequency transformers rau switching fais fab mov
Kev suav cov mis: N=0.4 (l/d) mus rau lub zog thib ob. (Qhov twg, N ib tug xov tooj ntawm lem, L ib absolute unit, luH=10 cubic. d - coil nruab nrab txoj kab uas hla (Cm).
Piv txwv li, winding L=0.04uH inductance coil, coj qhov nruab nrab txoj kab uas hla d=0.8cm, ces tus naj npawb ntawm N=3 tig. Thaum xam tus nqi, tus lej hloov N yog me ntsis loj dua. Lub inductance tuaj yeem hloov kho nyob rau hauv ib qho chaw.
Tus naj npawb ntawm cov hauv paus hniav ntawm ib lub kauj tsis tas yuav tsum muaj pes tsawg tus lem, tsuas yog thaum tus naj npawb ntawm cov kab sib txuas winding yog sib npaug rau 1, cov xov tooj ntawm cov hauv paus hniav ntawm ib kauj yog sib npaug rau cov xov tooj ntawm cov kauj. Muaj kev sib raug zoo hauv qab no: tus naj npawb ntawm tus neeg xyuas pib hauv paus ntawm lub kauj ib kab sib txuas winding hauv paus x tus lej hloov tus lej ntawm cov xov hlau hauv txhua qhov ntawm lub cev muaj zog stator yog tus naj npawb ntawm cov xov hlau hauv txhua qhov sib npaug ntawm cov xov tooj ntawm cov xov hlau hauv txhua qhov ntawm lub cev muaj zog stator. ib txheej winding; nyob rau hauv ob txheej winding, tus xov tooj ntawm cov xov hlau nyob rau hauv txhua qhov yog ob zaug tus naj npawb ntawm lem ie, 2 x tus naj npawb ntawm lem.
1, high-frequency transformer yog tsuas yog siv nyob rau hauv high-frequency switching fais fab mov rau high-frequency switching fais fab mov transformer, kuj siv nyob rau hauv high-frequency inverter fais fab mov thiab high-frequency inverter vuam tshuab rau high-frequency inverter fais fab mov transformer. Raws li kev ua haujlwm zaus, tuaj yeem muab faib ua ntau qib: 10kHz-50kHz, 50kHz-100kHz, 100kHz-500kHz, 500kHz-1MHz, 10MHz thiab siab dua.
2. Thaum lub sijhawm hloov pauv ntawm cov txheej txheem sib kis, cov dej xau inductance thiab kev faib tawm tuaj yeem ua rau inrush tam sim no thiab spike voltage, nrog rau sab saum toj oscillation, ua rau muaj kev poob ntau ntxiv.
