3. Qhov thib ob sab ntawm lub tshuab hloov pauv induces ib tug high-frequency voltage, uas yog rectified thiab lim los muab lub load;
4. Cov khoom tso tawm tau rov qab mus rau qhov kev tswj xyuas los ntawm ib lub voj voog los tswj lub voj voog pWM kom ua tiav lub hom phiaj ntawm cov zis ruaj khov.
Thaum lub zog AC nkag mus, nws feem ntau dhau los ntawm qee yam zoo li lub voj voog tam sim no los lim tawm qhov cuam tshuam ntawm daim phiaj hluav taws xob, thiab tib lub sijhawm lim tawm qhov cuam tshuam los ntawm cov khoom siv hluav taws xob mus rau hauv daim phiaj hluav taws xob;
Thaum lub hwj chim zoo ib yam, qhov siab dua qhov hloov zaus, qhov me me ntawm qhov hloov pauv hloov, tab sis qhov siab dua qhov yuav tsum tau ua rau lub raj hloov pauv;
Qhov thib ob ntawm kev hloov pauv hloov pauv tuaj yeem muaj ntau yam windings lossis winding nrog ntau cov kais dej kom tau txais cov khoom tsim nyog;
Feem ntau, qee qhov kev tiv thaiv Circuit Court yuav tsum tau ntxiv, xws li tsis muaj-load, luv-circuit thiab lwm yam kev tiv thaiv, txwv tsis pub lub switching fais fab mov yuav raug hlawv.
Feem ntau 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 Frequency Switching DC Power Supply
High-frequency switching DC fais fab mov [1] siv high-zoo imported IGBT raws li lub ntsiab lub hwj chim ntaus ntawv, thiab siv ultra-microcrystalline (tseem hu ua nanocrystalline) mos magnetic alloy khoom raws li lub ntsiab transformer core. Lub ntsiab tswj system adopts multi-loop tswj tshuab. Cov tshuaj tiv thaiv ntsev acidification ntsuas tau ua. Cov khoom siv hluav taws xob muaj cov qauv tsim nyog thiab muaj kev ntseeg tau zoo. Cov khoom siv hluav taws xob tau dhau los ua cov khoom tshiab ntawm thyristor fais fab mov vim nws qhov me me, lub teeb yuag, kev ua haujlwm siab, thiab kev ntseeg siab. Nws yog tsim rau ntau yam precision nto kho qhov chaw xws li kev sim, oxidation, electrolysis, galvanizing, npib tsib xee plating, tin plating, chrome plating, photoelectricity, smelting, tshuaj tsim, corrosion, thiab lwm yam nyob rau hauv anodizing, nqus txheej, electrolysis, electrophoresis, dej. kev kho mob, hluav taws xob khoom laus, hluav taws xob cua sov, electrochemistry, thiab lwm yam, nws kuj tau txais kev qhuas los ntawm cov neeg siv. Tshwj xeeb tshaj yog nyob rau hauv pCB, electroplating, thiab electrolysis industries, nws tau dhau los ua cov khoom siv hluav taws xob nyiam rau ntau tus neeg siv khoom.
Daim ntawv thov nta
1. Txo cov porosity, qhov tsim ceev ntawm crystal nuclei yog ceev tshaj qhov kev loj hlob ceev, uas txhawb nqa cov refinement ntawm crystal nuclei.
2. Txhim kho txoj hlua khi, ua kom cov zaj duab xis passivation tawg, thiab pab kev sib xyaw ua ke ntawm cov substrate thiab txheej txheej.
3. Txhim kho lub peev xwm npog thiab dispersing muaj peev xwm, lub siab cathode tsis zoo muaj peev xwm kuj tso cov passivated qhov chaw nyob rau hauv zoo tib yam electroplating, thiab qeeb "hlawv" thiab "dendritic" ntawm lub protruding qhov chaw ntawm complex qhov chaw vim noj ntau heev ntawm deposited ions. Rau qhov tsis xws luag ntawm deposition, lub thickness ntawm ib txheej nrog ib tug muab cov yam ntxwv (xws li xim, tsis muaj porosity, thiab lwm yam) yuav txo tau mus rau 1/3 ~ 1/2 ntawm tus thawj, txuag raw cov ntaub ntawv.
4. Txo qhov kev ntxhov siab sab hauv ntawm txheej txheej, txhim kho lattice defects, impurities, voids, qog, thiab lwm yam., yooj yim kom tau cov txheej txheem tawg-dawb, thiab txo cov additives.
5. Nws yog qhov zoo kom tau txais cov txheej txheem alloy nrog ruaj khov.
6. Txhawm rau txhim kho qhov tawg ntawm anode, tsis tas yuav tsum muaj anode activator.
7. Txhim kho cov neeg kho tshuab thiab cov khoom siv lub cev ntawm cov txheej, xws li ua kom muaj zog, txhim kho kev ua kom nruj, txhim kho kev ua haujlwm, corrosion tsis kam thiab tswj lub hardness ntawm txheej.
Kev sib xyaw ntawm DC switching fais fab mov
Tag nrho cov txheej txheem ntawm cov khoom siv hluav taws xob ncaj qha thiab lub ntsiab ntawm AC daim phiaj thiab DC tso zis: [
1. Input filter: Nws muaj nuj nqi yog lim cov clutter uas twb muaj lawm nyob rau hauv daim phiaj fais fab, thiab tib lub sij hawm tiv thaiv cov clutter generated los ntawm lub tshuab los ntawm pub rov qab mus rau pej xeem lub hwj chim daim phiaj.
2. Rectification thiab filtering: ncaj qha rectify AC zog ntawm daim phiaj mus rau ib tug smoother DC rau theem tom ntej ntawm transformation.
3. Inversion: Hloov cov rectified direct tam sim no mus rau high-frequency alternating tam sim no, uas yog ib feem ntawm lub high-frequency switching fais fab mov. Qhov ntau zaus, qhov me me ntawm qhov ntim, qhov hnyav thiab qhov tso zis zog.
4. Tso zis rectification thiab filtering: Raws li load yuav tsum, muab ruaj khov thiab txhim khu kev qha DC fais fab mov.
