Taw qhia rau zaus converter hloov fais fab mov rau kev kho zaus converters
Lub tshuab hluav taws xob hloov hluav taws xob muab lub zog rau kev tswj tag nrho ntawm cov zaus hloov pauv, uas yog qhov yuav tsum tau ua ua ntej rau kev ua haujlwm ib txwm muaj ntawm lub tshuab hloov pauv zaus. Hloov hom fais fab mov Circuit Court siv nyob rau hauv zaus converters yog ib tug DC AC nruam inverter Circuit Court, uas yog ib tug voltage thiab lub hwj chim converter uas converts DC voltage thiab hwj chim rau hauv mem tes voltage, thiab ces rectifies nws mus rau hauv lwm DC voltage. Lub input thiab output voltage yog cais los ntawm ib tug hloov transformer, uas plays lub luag hauj lwm nyob rau hauv lub hwj chim kis tau tus mob thiab voltage / tam sim no conversion. Lub tshuab hluav taws xob hloov pauv yog ib kauj ruam-down transformer. Cov yam ntxwv ntawm kev hloov hom fais fab mov yog raws li nram no:
1) Lub oscillation thiab voltage tswj txoj kev hloov cov khoom siv hluav taws xob yog los kho cov zis hluav taws xob los ntawm kev hloov cov mem tes dav lossis lub sijhawm, uas yog hu ua lub sijhawm tswj hwm. Nws kuj tau muab faib ua PWM (dav hloov kho) thiab PFM (ntau zaus hloov kho) txoj hauv kev.
2) Los ntawm lub zog hloov pauv yam ntxwv ntawm lub voj voog, nws tuaj yeem muab faib ua ob hom kev ua haujlwm: pem hauv ntej thiab flyback. Thaum lub raj xa hluav taws xob saturates thiab ua, lub rectifier txuas nrog rau qhov thib ob winding raug txiav tawm vim qhov rov qab tsis ncaj ncees lawm, thiab thawj winding ntawm switching transformer ntws tam sim no thiab khaws lub zog (electromagnetic conversion). Thaum lub tshuab hluav taws xob raug kaw, qhov thib ob winding tso tawm hluav taws xob hluav taws xob (magneto hluav taws xob hloov dua siab tshiab) los ntawm cov khoom siv hluav taws xob. Txoj kev excitation rau pem hauv ntej yog qhov rov qab thiab muaj kev txwv tsis pub siv.
3) Los ntawm qhov kev xav ntawm lub hauv paus Circuit Court qauv ntawm kev hloov pauv hloov pauv, muaj ob hom kev siv hluav taws xob: cov uas muaj cov khoom sib cais thiab cov sib xyaw ua ke oscillation chips. Yog li ntawd, los ntawm lub hauv paus ntawm oscillation signals, lawv muaj peev xwm muab faib mus rau hauv tus kheej-excited (discrete qhov chaw) thiab cais zoo siab (IC Circuit Court) hloov cov khoom siv fais fab. Ob qho tib si circuits muaj kev siv.
4) Hloov cov raj tuaj yeem siv cov khoom siv bipolar lossis cov khoom siv hluav taws xob ua haujlwm.
5) Lub zog hluav taws xob me me siv ib qho kawg rau pem hauv ntej Circuit Court, thaum lub zog loj thiab nruab nrab lub zog hluav taws xob feem ntau siv ob qho kawg rau pem hauv ntej. Hloov hom fais fab mov ntawm cov zaus hloov pauv feem ntau muab cov khoom siv hluav taws xob hauv qab no:+5V fais fab mov rau CPU thiab pab pawg, tswj circuits, thiab cov chaw ua haujlwm ua haujlwm; ± 15V fais fab mov rau tam sim no, voltage, kub thiab lwm yam txhaum kev kuaj xyuas circuits thiab tswj circuits; 24V fais fab mov rau tswj terminals thiab ua hauj lwm relay coils. Lub zog hluav taws xob ntawm plaub qhov kev sib cais sib cais tsav tsheb nrog qhov hluav taws xob ntawm 22V feem ntau ua tiav rau hauv +15V, -7.5V cov khoom siv hluav taws xob zoo thiab tsis zoo los ntawm qhov hluav taws xob stabilizing Circuit Court los muab qhov zoo siab tam sim no rau IGBT inverter tso zis Circuit Court.
Qhov tsis ua haujlwm ntawm lub zog hluav taws xob hauv ib qho khoom siv hluav taws xob yog ib txwm siab heev vim tias nws yuav tsum tau muab lub zog rau tag nrho lub tshuab, uas yog lub nra hnyav tshaj plaws. Qhov hloov hluav taws xob hloov hluav taws xob ntawm lub zaus hloov pauv yog qhov yooj yim hauv daim ntawv thiab qauv. Txawm li cas los xij, cov kab hluav taws xob yooj yim kuj tuaj yeem ua rau muaj qhov yuam kev nyuaj. Kev saib xyuas ntawm cov khoom siv hluav taws xob hloov pauv tsis yog qhov xav tau zoo li cov khoom siv hluav taws xob linear. Txhua qhov txuas me me hauv Circuit Court, xws li oscillation, voltage stabilization, kev tiv thaiv, thiab kev thauj khoom txawv txav, tuaj yeem ua rau muaj ntau yam teeb meem txhaum cai hauv Circuit Court.
Tsis muaj lus teb tom qab lub hwj chim rau, tsis muaj cov zaub ntawm lub lag luam tso saib vaj huam sib luag, thiab lub zaus converter zoo li tsis tau powered. Kev tswj qhov hluav taws xob thiab 10V zaus hloov qhov hluav taws xob ntawm qhov ntsuas ntsuas qhov ntsuas hluav taws xob yog ob qho tib si 0. Yog tias qhov tsis kam ntawm lub ntsiab txuas hluav taws xob ntawm qhov hloov pauv zaus yog qhov qub, nws tuaj yeem xaus lus tias qhov teeb meem yog nyob rau hauv qhov hloov fais fab mov Circuit Court.
