Cov thev naus laus zis tseem ceeb ntawm siab - muaj peev xwm hloov hluav taws xob tsim khoom tsim thiab lub luag haujlwm tseem ceeb ntawm hluav taws xob Bimetal Hu rau Rivets

Nrog rau kev txhim kho txuas ntxiv ntawm kev sib txuas lus thiab cov cuab yeej siv hluav taws xob hauv kev lag luam, kev lag luam tau muab cov kev xav tau siab dua ntawm kev ntsuas hluav taws xob, kev ua haujlwm ruaj khov, thiab muaj peev xwm nthuav dav ntawm siab - muaj peev xwm DC hloov hluav taws xob khoom siv. Cov kev daws teeb meem zoo sib xws rau cov me me - fais fab modules feem ntau raug kev txom nyem los ntawm qhov tsis zoo tam sim no sib qhia qhov tseeb, kev cuam tshuam kev sib raug zoo siab, thiab kev ruaj ntseg tsis txaus, ua rau lawv tsis haum rau siab - fais fab kev lag luam scenarios. Yog li ntawd, kev ua kom zoo ntawm cov khoom siv hluav taws xob topology thiab kov yeej cov teeb meem hauv kev kho hluav taws xob, kev tswj kom ruaj khov, thiab kev sib koom ua ke tam sim no tau dhau los ua qhov tseem ceeb hauv kev tsim cov khoom siv hluav taws xob siab -. Lub teeb liab hloov cov khoom nyob rau hauv lub hwj chim tswj Circuit Court feem ntau siv Composite Contact Rivets rau Relay, uas, nrog rau lawv zoo heev switching stability, xyuas kom meej meej thiab yuam kev - dawb tswj teeb liab kis tau tus mob.

Standardized siab- muaj peev xwm hloov hluav taws xob khoom siv feem ntau muaj ob lub modules: lub ntsiab fais fab Circuit Court thiab lub ntse tswj Circuit Court. Cov qauv siab- kawg yog nruab nrog PIC microcontroller los tsim kom muaj cov lej tswj hwm, ua kom muaj txiaj ntsig tiag - lub sijhawm ntsuas ntsuas, ceeb toom txhaum cai, thiab tswj chaw taws teeb. Lub ntsiab Circuit Court feem ntau siv H-bridge inverter topology. Txhawm rau ua kom yooj yim cov txheej txheem tsim khoom thiab txo cov nqi khoom siv, kev tsim khoom siv feem ntau siv cov cuab yeej paub tab nyuaj- hloov tshuab, ua kom muaj txiaj ntsig zoo ntawm kev hloov pauv thiab kev ua haujlwm tau zoo los ntawm kev sib piv cov qauv hloov pauv thiab lub zog hluav taws xob. Lub siab-ntau zaus ua haujlwm sib cuag hauv cov cuab yeej nyiam siv Silver Cadmium Hluav Taws Xob Sib Txuas, uas yog arc-tiv taus, qaug zog{11}} tiv taus, thiab haum rau siab - zaus pib- nres ua haujlwm.

Tsis tshua muaj hluav taws xob zoo thiab muaj kev cuam tshuam loj heev yog qhov tsis xws luag hauv cov khoom siv hluav taws xob siab - lub peev xwm, thiab peb -theem ib zaug- hloov PFC lub zog hloov kho thev naus laus zis yog qhov tseem ceeb los daws qhov teeb meem no. Kev lag luam siab- cov khoom siv hluav taws xob muaj peev xwm feem ntau sib xws nrog 380V peb-theem AC cov kab nkag. Los ntawm kev ntxiv PFC circuits rau sab tswv yim ntawm txhua qhov module, txawm tias muaj qhov hloov pauv ntawm qhov hluav taws xob ntawm ± 20%, DC lub npav hluav taws xob tseem tuaj yeem khaws cia ruaj khov ntawm 670VDC. Qhov no tsis yog tsuas yog txhim kho lub zog tag nrho thiab ua kom muaj kev sib haum xeeb tab sis kuj txo qhov loj ntawm downstream inverter transformer. Lub hauv paus tswj nti ntawm qhov kev kho Circuit Court no yog UC1854, ua ke nrog ib qho -inductor qauv, uas ua rau muaj cov qauv yooj yim thiab kho tau zoo heev. Nws nta Silver Cadmium Oxide Agcdo Hluav taws xob tiv tauj, uas yog siab -kub resistant, qis{16}} poob, thiab haum rau siab -voltage rectification tej yam kev mob.

Qhov system tsis ruaj khov thiab cov lus qhia tsis tseeb tam sim no tshwm sim yog cov ntsiab lus mob tseem ceeb hauv kev nyuaj - hloov hluav taws xob tsim qauv. Feem ntau tam sim no - hom PWM maub los yog qhov ua rau tsis raug tig- tawm ntawm kev hloov khoom siv vim ua rau - ntug glitches nyob rau hauv lub waveform tam sim no, ua rau lub hwj chim tso zis oscillations thiab kev ua haujlwm txawv txav. Lub ntsiab kev lag luam optimization tov siv ramp them technology, uas tshem tawm tag nrho cov waveform glitches los ntawm kev sib txuas capacitors nyob rau hauv parallel nyob rau hauv lub tam sim no transformer thiab ntxiv ib tug RC lim qauv ntawm qhov chaw nres nkoj tswj. Nyob rau tib lub sijhawm, ob lub kaw - lub tswv yim tswj lub voj voog nrog lub voj voog sab hauv thiab sab nrauv yog siv los kho qhov tso zis voltage thiab tam sim no, txhim kho qhov kev ua tau zoo thiab zoo li qub ntawm cov khoom siv hluav taws xob. Cov khoom tseem ceeb ntawm kev tswj module siv Agcdo Bimetal Silver Rivet Contacts, uas yog cov teb tau zoo thiab hloov tau mus rau siab -precision kaw- txoj cai tswj lub voj voog.

Multi-module parallel tam sim no sib koom tshuab yog lub hauv paus kev txhawb nqa rau kev nthuav dav cov khoom siv hluav taws xob. Kev sib koom tsis sib xws tuaj yeem ua rau cov khoom thauj khoom tsis sib xws, thaj chaw overheating, thiab txo qis hauv cov khoom siv lifespan. Kev lag luam tseem ceeb tam sim no- tus qauv kev ywj pheej tam sim no sib koom kev daws teeb meem yog nyob ntawm UC3902 nplooj siab sib qhia chip tam sim no. Siv lub tsheb npav voltage tawm tswv yim thiab cov yam ntxwv ntawm kev coj tus kheej ntawm diodes, nws cia li txheeb xyuas tus tswv module nrog cov khoom loj tshaj plaws, thaum cov tub qhe tseem tshuav cov nqi siv tam sim no hauv lub sijhawm tiag tiag, dynamically kho PWM lub luag haujlwm mus rau qhov kawg ua tiav qhov nyiaj tshuav tam sim no thoob plaws txhua qhov sib npaug. Tus tsim yuav tsum tau configuring ib resistor - capacitor buffer qauv ntawm lub nti pins kom tsis txhob muaj qhov system oscillations tshwm sim los ntawm kev tsis sib haum xeeb hloov rhythms. Cov kev sib txuas sib txuas sib txuas siv Silver Copper Composite Rivet Contacts, kom ntseeg tau tias muaj kev sib raug zoo thiab txo qis kev sib koom ua haujlwm tam sim no.

Kev xaiv cov khoom tsim nyog thiab cov txheej txheem ua kom zoo dua yog qhov tseem ceeb los ua kom ntseeg tau ntev - lub sijhawm ua haujlwm ruaj khov ntawm cov khoom siv hluav taws xob. Nyob rau hauv siab - zaus hloov pauv thiab hloov pauv hloov pauv hloov pauv, cov kev sib cuag sab hauv ntawm cov khoom siv hluav taws xob muaj feem cuam tshuam rau cov teeb meem xws li ablation, oxidation, thiab nce kev tiv thaiv, cuam tshuam ncaj qha rau kev sib koom tam sim no thiab cov khoom tsim tawm. Xaiv cov khoom tiv tauj uas haum rau siab - lub zog ua haujlwm yog qhov tseem ceeb heev. Silver Cadmium Oxide Bimetallic Contact Rivets muaj qhov zoo xws li arc tsis kam, oxidation tsis kam, thiab hnav tsis kam, zoo haum rau qhov siab - zaus hloov kho cov yam ntxwv ntawm siab - muaj peev xwm siv hluav taws xob.

Txhawm rau txheeb xyuas qhov ua tau thiab kev ruaj ntseg ntawm tag nrho cov qauv tsim, kev lag luam tau ua qhov kev sim ua haujlwm tshwj xeeb ntawm ntau qhov siab - fais fab mov qauv qauv. Cov txiaj ntsig kev ntsuas pom tau hais tias qhov kev ua tau zoo ntawm cov khoom siv hluav taws xob tau ua tiav qhov kev tswj hwm qhov tseeb ntawm 0.1%, kev tswj hwm tam sim no ntawm 0.08%, kev thauj khoom dhia dynamic teb tsuas yog 150μs, qhov siab tshaj plaws tag nrho ntawm 91%, thiab qhov tsis sib xws tam sim no ntawm ntau qhov sib npaug yog tswj nruj me ntsis hauv ± 3%. Txhua qhov ntsuas tau ua tau raws qib siab -kawg cov qauv kev lag luam. Qhov kev ua tau zoo tshaj plaws no yog nyob ntawm kev txhawb nqa ruaj khov ntawm kev sib cuag precision. Hu rau Hluav Taws Xob Bi-hlau Sib cuag Rivets tuaj yeem hloov kho rau qhov hloov pauv tam sim no, ua kom muaj kev hloov pauv ruaj khov hauv txhua qhov kev ua haujlwm.
