yuav ua li cas xaiv tus Shape ntawm High Frequency Sib Nqus Core nyob rau hauv Switching Power Supply

High zaus transformer yog ib qho khoom siv rau kev hloov AC voltage, tam sim no thiab impedance. Thaum AC tam sim no dhau los ntawm thawj kauj, AC magnetic flux yuav raug tsim nyob rau hauv cov tub ntxhais hlau (los yog cov tub ntxhais sib nqus), uas yuav induce voltage (los yog tam sim no) nyob rau hauv lub thib ob kauj. Lub transformer yog tsim los ntawm ib tug hlau core (los yog magnetic core) thiab ib kauj. Lub coil muaj ob los yog ntau tshaj windings. Lub winding txuas nrog lub hwj huam mov yog hu ua thawj kauj, thiab lwm qhov windings yog hu ua theem nrab kauj. Sib nqus cores ntawm transformer muaj xws li tank hom tub ntxhais, RM hom tub ntxhais, E hom tub ntxhais, EC, ETD thiab EER hom tub ntxhais, PQ hom tub ntxhais, EP hom tub ntxhais, EP hom tub ntxhais, annular cores thiab lwm yam sib nqus cores. Cov hlau nplaum no cuam tshuam li cas rau kev ua haujlwm ntawm transformer? Tam sim no cia saib qhov kev tsom xam tshwj xeeb.

1, Lub lauj kaub cores
Lub cev pob txha thiab winding yog yuav luag tag qhwv los ntawm cov hlau nplaum, uas ua rau nws zoo heev rau EMI shielding; Qhov loj ntawm lub tank hom magnetic core ua raws li tus qauv IEC, thiab kev sib hloov tau zoo heev thaum tsim khoom; Nws tuaj yeem muab cov pob txha yooj yim (tsis muaj tus pin) thiab PCB mounting skeleton (nrog tus pin); Vim yog qhov tsim ntawm lub tank zoo, tus nqi siab dua li lwm hom hlau nplaum nrog qhov loj me; Vim tias nws cov duab tsis zoo rau cov cua sov dissipation, nws tsis haum rau high-power transformer inductors.

2.RM ferrite tub ntxhais
Piv nrog lub lauj kaub hom cores, ob sab symmetrical ntawm lub lauj kaub hom raug txiav tawm, uas yog qhov zoo tshaj rau cov cua sov dissipation thiab txhuas tawm ntawm qhov loj; Piv nrog rau lub tank zoo, nws txuag tau li ntawm 40 feem pua ​​​​ntawm qhov chaw nruab; Seb lub cev pob txha muaj koob hom thiab tus pin hom; Ib khub ntawm clips tuaj yeem siv rau kev teeb tsa; RM hom sib nqus core tuaj yeem ua rau hauv cov duab tiaj tus (tsim rau lub hom phiaj tam sim no los yog cov tub ntxhais sib nqus tuaj yeem sib dhos ncaj qha rau lub rooj tsav xwm luam tawm nrog cov windings tsim); Txawm hais tias cov nyhuv shielding tsis zoo li lub lauj kaub hom, nws tseem zoo.

4. E-core

Piv nrog rau lub tank hom magnetic core, tus nqi ntawm E-hom magnetic core yog qis dua. Tsis tas li ntawd, qhov winding thiab sib dhos yog qhov yooj yim. Cov tub ntxhais hlau nplaum no yog tam sim no siv dav tshaj plaws, tab sis nws qhov tsis zoo yog tias nws tsis tuaj yeem muab kev tiv thaiv tus kheej; E-type magnetic cores tuaj yeem ntsia tau rau hauv cov lus qhia sib txawv, los yog ob peb khub ntawm cov hlau nplaum sib nqus tuaj yeem muab tso rau siv ntau lub zog; Cov tub ntxhais hlau nplaum tuaj yeem ua rau hauv cov duab tiaj tus (uas yog ib qho nrov sib nqus core zoo rau cov qauv transformers tam sim no); Koob pub dawb thiab tus pin hom skeletons tuaj yeem muab tau; Vim tias nws cov cua kub dissipation zoo heev thiab nws tuaj yeem siv ua ke, feem ntau muaj zog inductors thiab transformers siv cov hlau nplaum ntawm cov duab no.

5. EC, ETD thiab EER cores

Cov qauv ntawm cov hlau nplaum no yog nruab nrab ntawm E-hom thiab hom tank. Zoo li E-hom magnetic core, lawv tuaj yeem muab qhov chaw txaus rau qhov loj hla ntu ua rau cov hlau lead tawm (tsim nyog rau cov qauv tam sim no ntawm cov khoom siv hluav taws xob tsawg tsawg); Cov cores zoo li no kuj muaj cov cua kub zoo heev; Txij li thaum lub hauv paus kem yog cylindrical, piv nrog lub cuboid nrog tib seem, qhov ntev ntawm ib zaug tig winding yog luv los ntawm 11 feem pua, uas txo cov tooj liab los ntawm 11 feem pua, thiab tib lub sij hawm, cov hlau nplaum muaj peev xwm muab tau ib tug tso zis ntau zog; Nyob rau tib lub sij hawm, lub hauv paus kem yog cylindrical, uas, piv nrog cov duab plaub hauv nruab nrab kem, kuj zam lub zais kev phom sij ntawm kev puas tsuaj rau winding hlau rwb thaiv tsev vim yog lub kaum sab xis thaum winding.

6. PQ hom sib nqus core

PQ hom magnetic core yog tsim tshwj xeeb rau inductor thiab transformer siv nyob rau hauv switching fais fab mov. Tus tsim ntawm PQ zoo optimizes qhov piv ntawm cov tub ntxhais ntim, qhov chaw nto thiab winding cheeb tsam; Qhov kev tsim no ua rau nws tuaj yeem siv cov tub ntxhais sib nqus me tshaj plaws los muab qhov siab tshaj plaws inductance thiab qhov siab tshaj plaws winding cheeb tsam; Nrog rau qhov tsim, qhov siab tshaj plaws tso zis hluav taws xob tuaj yeem tau txais nrog qhov tsawg kawg nkaus transformer ntim thiab qhov hnyav, thiab qhov tsawg kawg nkaus PCB installation qhov chaw tuaj yeem nyob; Ib khub ntawm clips tuaj yeem siv rau kev teeb tsa thiab kho; Qhov kev tsim qauv zoo no kuj ua rau thaj chaw sib nqus hauv cheeb tsam ntawm cov tub ntxhais sib nqus ntau dua, yog li cov qauv no tseem ua rau nws muaj peev xwm muaj qhov kub tsawg dua li lwm cov qauv tsim.

7. EP hom magnetic core

Lub voj voog hauv nruab nrab kem cov qauv ntawm EP hom sib nqus core tag nrho qhwv lub winding tshwj tsis yog rau qhov kawg kev sib cuag nrog PCB board, thiab shielding zoo heev; Cov duab tshwj xeeb no txo ​​qis qhov cuam tshuam ntawm huab cua sib txawv uas tsim los ntawm qhov chaw sib cuag thaum lub sij hawm sib dhos ntawm ob lub sib nqus cores, thiab muab lub ntim loj dua thiab tag nrho qhov chaw siv qhov sib piv.

8. Toroidal tub ntxhais

Rau cov tuam txhab, lub annular sib nqus cores yog qhov kev lag luam tshaj plaws, thiab nws cov nqi yog qhov qis tshaj ntawm cov sib piv sib nqus cores; Vim yog siv cov pob txha, cov nqi ntxiv thiab kev sib dhos yog sib npaug ntawm xoom; Thaum tsim nyog, lub tshuab winding tuaj yeem siv rau winding; Nws txoj kev tiv thaiv kuj zoo heev.
