Nyob rau hauv kev saib ntawm txoj kev loj hlob kev taw qhia nyob rau hauv xyoo tas los no thiab cov cuab yeej ntawm rectifiers, cov kws txawj tau soj ntsuam thiab txiav txim siab cov ntsiab lus tseem ceeb hauv qab no: Ua ntej, nyob rau hauv lub terminology ntawm Schottky diodes, Schottky mas yog tsim los ntawm planar mus rau trench kom txo reverse to tam sim no. Yog vim li cas rau qhov kev hloov pauv no yog Schottky, txhawm rau ua tiav qhov hluav taws xob qis, yuav ua rau qhov rov qab xau tam sim no nce, thiab qhov zawj tuaj yeem txhim kho qhov rov qab ntws tawm tam sim no thiab txo qhov rov qab xau tam sim no. Nyob rau hauv cov nqe lus ntawm ntim, high-frequency rectifiers ntsib txoj kev loj hlob ntawm SMD ntim.
Transformer khoom tshwj xeeb
Kev tsim cov khoom siv hluav taws xob ntau zaus feem ntau suav nrog pn hlws ris hloov diodes, ceev rov qab diodes, qauv rov qab diodes, choj pawg, Zeners, cov khoom siv hluav taws xob tsis ntev los no, TV, thiab cov khoom tiv thaiv kev tiv thaiv ib ntus hu ua thyristors TSPD. Tsis tas li ntawd, Schottky diodes thiab rectifiers tsim siv MOSFET technology hu ua SBR (Super Blocking Rectifier).
Cov kws tshaj lij tau taw qhia ntxiv tias cov yam ntxwv ntawm SBR yog qis dua li ntawm Schottky, thiab qhov rov qab xau tam sim no tsawg dua li Schottky. Qhov no yog kev sib xyaw ua ke ntawm qhov zoo ntawm Schottky thiab hloov diodes. SBR technology ultra-thin ntim tuaj yeem ua tau raws li cov neeg siv khoom qhov loj me thiab qhov xav tau ceev tam sim no. Nws hais tias hauv kev lag luam photovoltaic, SBR cov khoom tuaj yeem ua tau raws li qhov xav tau ntawm qhov sib txuas ntawm qhov kub ntawm 200 degree, thiab cov xau tam sim no tsawg heev. Tsis tas li ntawd, nyob rau hauv kev hloov ntawm pn hlws ris diode thiab high-frequency Schottky diode rectifier, cov khoom zoo li me me thiab qhov ceev tam sim no tau nce. Cov kws tshaj lij hais tias PowerDI ntim tshuab tuaj yeem ua rau muaj qhov ceev tam sim no. Piv txwv li, nyob rau hauv cov ntaub ntawv ntawm SOD123 pob, 1A tam sim no tuaj yeem nqa los ntawm shoteki, tab sis qhov sib xyaw ntawm SOD123 pob tuaj yeem ncav cuag 3A; Piv txwv li, schottky dav tsuas tuaj yeem tiv taus 0.5a tam sim no hauv SOD323 pob, thaum nyob hauv PowerDI323 (SOD123 Hauv hom ntim khoom siv tau zoo, tam sim no txawm mus txog 2A.

Txoj kev loj hlob ntawm high-frequency rectifiers yog siv dav hauv cov ntaub ntawv, kev sib txuas lus, khoom siv hauv tsev, khoom siv hauv chaw ua haujlwm, ntsuas / tswj cov cuab yeej (nrog rau ntau yam kev kho mob, kev tiv thaiv hauv tebchaws, aerospace, tsheb thauj mus los, thiab lwm yam). Yeej, rectifiers yog ib feem tseem ceeb ntawm lub hwj chim tswj module ntawm cov khoom siv hluav taws xob. Nyob rau tib lub sijhawm, piv nrog cov khoom siv hluav taws xob dav dav, tsuas muaj lub neej voj voog ntawm 3 mus rau 12 lub hlis. Lub neej voj voog ntawm high-frequency rectifiers yog ntev heev thiab tsis cuam tshuam. Cov kev lag luam tshwj xeeb thiab cov ntawv thov tshwj xeeb raug cuam tshuam los ntawm kev hloov pauv huab cua. Yog li ntawd, feem ntau, tag nrho qhov kev thov rau cov khoom siv rectifier tuaj yeem loj hlob zoo nrog kev txhim kho ntawm ntau yam khoom siv hluav taws xob.
