DC switching fais fab mov ua hauj lwm hauv paus ntsiab lus DC switching power supply classification
DC switching fais fab mov yog siv los tswj lub switching tube los ntawm Circuit Court rau high-ceev conduction thiab txiav tawm. Lub alternating tam sim no yuav muab rau lub transformer hloov mus rau hauv high-frequency ncaj tam sim no, yog li tsim qhov yuav tsum tau ib los yog ntau tshaj voltage! Hloov mus rau high-frequency alternating tam sim no yog vim li cas high-frequency alternating tam sim no nyob rau hauv lub transformer converter Circuit Court yog npaum li cas npaum li cas tshaj 50HZ. Yog li qhov hloov pauv hloov pauv tuaj yeem ua rau me me, thiab kev ua haujlwm tsis kub heev! Tus nqi qis heev. Yog tias koj tsis hloov 50HZ rau hauv high-frequency switching fais fab mov tsis muaj nuj nqis!
Txoj cai ntawm kev ua haujlwm
1. AC fais fab input rectified thiab lim rau DC.
2. Los ntawm lub high-frequency pWM (mem tes dav modulation) teeb liab tswj switching tube, lub DC ntxiv rau lub switching transformer ntawm thawj.
3. Cov hloov pauv hloov pauv hloov pauv hloov pauv ua rau muaj qhov hluav taws xob ntau zaus, uas yog kho thiab lim thiab xa mus rau lub nra.
4. Cov khoom tso tawm yog pub rov qab mus rau cov tswj hluav taws xob los ntawm qee lub voj voog los tswj lub voj voog pWM kom ua tiav lub hom phiaj ntawm cov zis ruaj khov.
AC fais fab input feem ntau los ntawm lub voj tam sim no xws li, lim tawm qhov cuam tshuam ntawm daim phiaj, tab sis kuj lim tawm lub hwj chim ntawm daim phiaj cuam tshuam.
Nyob rau hauv tib lub zog, qhov siab dua qhov hloov zaus, qhov me me ntawm qhov hloov pauv hloov pauv, tab sis qhov siab dua qhov yuav tsum tau muaj ntawm lub raj hloov pauv.
Qhov thib ob ntawm kev hloov pauv hloov pauv tuaj yeem muaj ntau tshaj ib qho winding lossis ib qho winding nrog ntau tshaj ib tus kais, thiaj li yuav tau txais cov khoom tsim nyog.
Feem ntau, qee qhov kev tiv thaiv Circuit Court yuav tsum tau ntxiv, xws li tsis muaj-load thiab luv luv-circuit tiv thaiv, txwv tsis pub lub switching fais fab mov yuav raug hlawv.
Feem ntau yog siv hauv kev lag luam thiab qee yam khoom siv hauv tsev, xws li TV teeb, khoos phis tawj, thiab lwm yam.
Classification ntawm DC switching fais fab mov
High zaus hloov DC fais fab mov
High-frequency switching DC fais fab mov [1] yog cov khoom siv zoo IGBT uas yog lub zog tseem ceeb, nrog ultra-microcrystalline (tseem hu ua nanocrystalline) cov khoom siv hlau nplaum sib nqus rau lub ntsiab transformer, lub ntsiab tswj system txais ntau yam. -loop tswj tshuab, cov qauv ntawm cov tshuaj tiv thaiv ntsev acidification ntsuas. Cov qauv ntawm cov khoom siv fais fab yog tsim nyog thiab txhim khu kev qha. Cov khoom siv hluav taws xob nrog nws qhov me me, lub teeb yuag, kev ua haujlwm siab, kev ntseeg siab ntawm kev ua tau zoo ntawm silicon tswj fais fab mov kom dhau los ua cov khoom siv tshiab. Nws yog tsim rau kev sim, oxidation, electrolysis, zinc plating, nickel plating, tin plating, chromium plating, photoelectricity, smelting, tshuaj tsim, corrosion thiab lwm yam precision nto kho qhov chaw. Hauv anodic oxidation, lub tshuab nqus tsev txheej, electrolysis, electrophoresis, dej kho, kev laus ntawm cov khoom siv hluav taws xob, hluav taws xob cua sov, electrochemistry, thiab lwm yam kuj tau txais cov neeg siv khoom zoo siab qhuas. Tshwj xeeb tshaj yog nyob rau hauv lub tshav pob ntawm pCB, electroplating, electrolysis kev lag luam, tau dhau los ua thawj qhov kev xaiv ntawm ntau cov neeg siv khoom fais fab khoom.
