Txoj cai ntawm High Frequency Switching Power Supply Module
Hnub no kuv xav qhia rau koj txog cov yam ntxwv ntawm high-frequency switching power supply module Lub hauv paus ntsiab lus ntawm high-frequency switching power supply module, tom ntej no kuv yuav yog los ntawm cov yam ntxwv ntawm high-frequency switching power supply module, lub hauv paus ntsiab lus ntawm high-frequency switching fais fab mov module, high-frequency switching power supply module tsis, high-frequency switching power supply module dustproof ntsuas, high-frequency switching power supply module ntawm cov kev taw qhia ntawm txoj kev loj hlob ntawm txoj kev loj hlob ntawm cov kev taw qhia ntawm lub module, uas yog ib tug ob peb yam ntawm no los qhia.
High-frequency switching power supply module yog tsim los ntawm ib tug loj tus naj npawb ntawm resistors, capacitors, lub hwj chim hluav taws xob, thiab lwm yam nyob rau hauv raws li tej yam circuitry, nyob rau hauv tus txheej txheem ntawm lub hwj chim hloov dua siab tshiab, yeej ib txwm tsim ib tug npaum li cas ntawm lub hwj chim poob, thiab lub hwj chim poob. feem ntau emitted nyob rau hauv daim ntawv ntawm tshav kub, thiaj li hais tias qhov kub ntawm lub hwj chim module nce. Kev kub siab dhau ntawm lub neej ntawm module muaj kev cuam tshuam zoo, qhov siab dua qhov kev ua haujlwm kub ntawm lub module, qhov kev ua haujlwm qis dua thiab kev ntseeg siab, lub neej ua haujlwm luv dua. Yog li ntawd, nyob rau hauv tas li ntawd mus rau ib tug siab kev cia siab ntawm lub Circuit Court mus kom ze, tab sis kuj yuav tsum tau xaiv qhov tsim nyog cov cua kub dissipation txoj kev, zoo txo qhov kub ntawm high-frequency switching fais fab mov module los xyuas kom meej tias cov kev pab cuam lub neej. Tam sim no siv nyob rau hauv hluav taws xob fais fab DC system ntawm high-frequency switching fais fab mov module, lub ntsiab siv ntawm yuam cua txias thiab ntuj txias ob txoj kev tshav kub dissipation.
Zaus switching fais fab mov module nta
1, kev ua haujlwm siab: ua tiav tag nrho cov load ntau ntawm xoom-voltage xoom-tam sim no hloov pauv, kom ntseeg tau tias lub raj xa hluav taws xob tsis muaj qhov kev kaw, qhov tam sim no yog qhov ntshiab sinusoidal yoj, kev hloov pauv me me; tso zis rectifier voltage kev nyuaj siab yog tsawg heev, tsis muaj rov qab tam sim no.
2, me me: kev ua haujlwm siab ntawm lub converter, piv nrog cov tsoos pWM hloov hluav taws xob topology kev pab cuam, lub rhaub dej ntim tuaj yeem raug txo los ntawm ib nrab.
3, kev ntseeg siab: los ntawm kev siv cov txheej txheem kev tsim kho hauv tsev, kev tiv thaiv zoo tshaj plaws thiab lub tswb ntsuas thiab xaiv cov khoom siv zoo thiab txhim khu kev qha tuaj txawv teb chaws, kom ua tiav qhov zoo tshaj plaws ntawm kev cuam tshuam tsis tshua muaj hluav taws xob hauv qhov no.
4, lub neej ntev: vim qhov kub thiab txias, tuaj yeem ncua kev laus nrawm ntawm cov khoom, yog li txhim kho cov khoom lag luam lub neej;
Ntau zaus
Txoj cai ntawm switching fais fab mov module
High-frequency switching module adopts passive pFC technology thiab advanced pulse width modulation control technology (pWM), uas ua rau module efficiency ntxiv thiab harmonics txo. Lub module txais AC peb-theem, peb-xaim 380VAC sib npaug input hom, tsis muaj ib nrab-xaim tam sim no poob. Module AC input los ntawm cov kab hluav taws xob tiv thaiv hluav taws xob thiab EMI nqus Circuit Court, tag nrho-bridge rectifier lim Circuit Court los kho qhov peb-theem AC voltage rau hauv lub zog DC voltage, los ntawm high-frequency mem tes width modulation converter rau hauv high-frequency square- yoj voltage, thiab tom qab ntawd los ntawm qhov tso zis rectifier lim Circuit Court, kom tau txais qhov ruaj khov tso zis voltage thiab tam sim no, nyob rau hauv daim phiaj hluav taws xob thiab kev thauj khoom hloov tawm tswv yim hloov kho Circuit Court los tswj lub mem tes dav modulation Circuit Court, kho cov mem tes dav, ua kom cov zis voltage. thiab tam sim no nyob ruaj khov, ua kom cov zis voltage thiab tam sim no nyob ruaj khov, ua kom cov zis voltage thiab tam sim no nyob ruaj khov. Thaum daim phiaj voltage thiab load hloov, lub tswv yim kho Circuit Court tswj lub mem tes dav modulation Circuit Court thiab kho qhov dav ntawm mem tes dav kom cov zis voltage thiab tam sim no ruaj khov.
