Cov duab ntawm high-frequency core, dab tsi cuam tshuam rau lub transformer?

Switching fais fab mov nyob rau hauv high-frequencytub ntxhaismuaj ntau heev, thaum koj ntsib cov duab sib txawv ntawm high-frequency core, koj tuaj yeem piav qhia lawv txawv li cas?

Lub high-frequency transformer yog ib yam khoom uas hloov AC voltage, tam sim no thiab impedance. Thaum muaj AC tam sim no nyob rau hauv thawj kauj, AC flux yog generated nyob rau hauv lub hlau core (los yog magnetic core), thiaj li hais tias lub voltage (los yog tam sim no) induced nyob rau hauv lub thib ob kauj. Lub transformer muaj ib tug hlau core (los yog magnetic core) thiab ib tug coil, uas muaj ob los yog ntau tshaj windings, uas lub winding txuas nrog lub hwj chim mov yog hu ua thawj kauj, thiab tus so yog hu ua thib ob kauj. Cov tub ntxhais sib nqus ntawm lub transformer muaj xws li tank core, RM core, E core, EC, ETD thiab EER core, PQ core, EP core, EP core, annular cores thiab lwm yam sib nqus cores, yog li cas cov hlau nplaum no cuam tshuam rau kev ua haujlwm ntawm lub tshuab hluav taws xob. transformer?

1, ua core

Lub cev pob txha thiab winding yog yuav luag txhua qhwv los ntawm cov hlau nplaum, uas ua rau muaj kev tiv thaiv zoo heev ntawm EMI; Qhov loj ntawm lub tank tub ntxhais yog raws li IEC cov qauv, thiab kev sib hloov tau zoo heev thaum tsim khoom. Yooj yim ncej (tsis muaj pins) thiab PCB board mounting ncej (nrog pins) muaj; Vim yog qhov tsim ntawm lub tank zoo, tus nqi yog siab dua li ntawm lwm hom sib nqus cores ntawm tib qhov loj; Vim tias nws cov duab tsis zoo rau cov cua sov dissipation, nws tsis haum rau siv nyob rau hauv high-power transformer inductors.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

2, RM hom sib nqus core

Piv nrog rau lub tank hom, ob sab symmetrical ntawm lub tank hom raug txiav tawm, uas yog ntau conducive rau tshav kub dissipation thiab loj-loj hlau lead extraction; Txuag li 40% ntawm qhov chaw teeb tsa piv rau lub lauj kaub zoo; Lub cev pob txha yog tsis muaj koob los yog koob ntxig; Ib khub ntawm clamps tuaj yeem siv rau kev teeb tsa; RM core tuaj yeem ua rau hauv cov duab tiaj tus (tsim rau niaj hnub no lub tiaj tus transformers los yog ncaj qha mounted rau ib tug luam board Circuit Court nrog twb tsim windings); Txawm hais tias cov nyhuv shielding tsis zoo li lub peev xwm, nws tseem zoo.

3, Hom E sib nqus core

Piv nrog rau cov tub ntxhais tank, tus nqi ntawm E core yog qis dua, ua ke nrog cov winding thiab sib dhos yog qhov yooj yim, cov tub ntxhais zoo li no yog siv dav tshaj plaws, tab sis nws qhov tsis zoo yog tias nws tsis tuaj yeem muab kev tiv thaiv tus kheej; Cov tub ntxhais E tuaj yeem ntsia tau rau hauv cov lus qhia sib txawv, thiab tseem tuaj yeem siv los siv ntau lub zog; Cov tub ntxhais hlau nplaum no tuaj yeem ua rau hauv cov duab tiaj tus (uas yog cov qauv tseem ceeb rau cov qauv hloov pauv tam sim no); Nws tuaj yeem muab tus pin-dawb thiab tus pin hom pob txha; Vim tias nws cov cua kub dissipation zoo heev thiab tuaj yeem siv tau rau hauv superposition, feem ntau high-power inductors thiab transformers siv sib nqus cores ntawm cov duab no.

4, EC, ETD thiab EER cores

Cov txheej txheem tseem ceeb no nyob nruab nrab ntawm hom E thiab hom tuaj yeem. Zoo li E core, lawv tuaj yeem muab qhov chaw txaus rau ib feem loj ntawm cov hlau lead (tsim nyog rau qhov tam sim no ntawm qhov tsis tshua muaj hluav taws xob thiab siab hloov hluav taws xob tam sim no); Cov cores zoo li no kuj dissipate tshav kub zoo heev; Thaum lub hauv nruab nrab kem yog cylindrical, piv nrog lub cuboid ntawm tib seem, qhov ntev ntawm ib leeg-tig winding yog luv luv los ntawm 11%, uas ua rau cov tooj liab poob kuj txo los ntawm 11%, thiab cov tub ntxhais hlau nplaum tuaj yeem muab tau. tso zis ntau zog; Nyob rau tib lub sijhawm, cov kab nruab nrab yog cylindrical, piv nrog lub cuboid nruab nrab kem, nws kuj zam qhov tsis txaus ntshai ntawm kev rhuav tshem cov rwb thaiv tsev ntawm cov hlau winding vim lub cuboid npoo yog qhov txhab.

5, PQ sib nqus core

PQ core yog tsim tshwj xeeb rau inductors thiab transformers rau kev hloov cov khoom siv fais fab. PQ zoo yog tsim los ua kom zoo dua qhov sib piv ntawm cov tub ntxhais ntim, thaj chaw saum npoo thiab qhov chaw winding. Qhov kev tsim no, kom qhov kev tsim no, nyob rau hauv qhov tsawg tshaj plaws transformer ntim thiab qhov hnyav, kom tau txais lub zog tso zis ntau tshaj plaws, thiab tuav lub PCB qhov chaw me me; Yuav siv tau ib tug them nyiaj clamp rau nruab taag; Qhov kev tsim qauv zoo no kuj ua rau cov hlau nplaum sib nqus ntawm qhov chaw sib nqus ntawm cov tub ntxhais sib nqus ntau dua, yog li cov qauv hlau nplaum no tseem ua rau cov qauv tsim ntawm cov tub ntxhais hlau nplaum muaj qhov kub tsawg dua li lwm cov qauv hlau nplaum.

6, EP tub ntxhais

EP core ntawm lub voj voog nruab nrab kem peb-seem qauv, ntxiv rau kev sib cuag nrog PCB pawg thawj coj saib kawg, tag nrho qhwv cov winding, shielding zoo heev; Cov duab tshwj xeeb no txo ​​qis qhov cuam tshuam ntawm qhov sib txawv ntawm huab cua tsim ntawm qhov chaw sib cuag thaum ob lub cores tau sib sau ua ke, thiab muab kev faib ua feem ntau ntawm qhov ntim thiab qhov chaw siv tag nrho.

7, Toroidal tub ntxhais

Rau cov chaw tsim khoom, lub nplhaib tseem ceeb yog qhov kev lag luam tshaj plaws, thiab nws cov nqi yog qhov qis tshaj ntawm ntau yam sib nqus cores uas tuaj yeem piv nrog nws. 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.

Cov saum toj no yog qhov kev soj ntsuam ntawm kev cuam tshuam ntawm cov tub ntxhais sib nqus zoo ntawm lub siab zaus transformer ntawm kev ua haujlwm ntawm transformer, thiab kuv vam tias nws tuaj yeem pab koj.Yog xav paub ntxiv, thov hu rau peb ntawmsales@xfullstar.com
