Kev tu cov txheej txheem ntawm high-power DC stabilized fais fab mov
Kev siv lub zog siab DC tswj fais fab yog qhov yooj yim heev. Thaum siv nws, koj yuav tsum tau them sai sai rau qhov polarity ntawm qhov yuav tsum tau DC voltage. Cov ntsiab lus tseem ceeb ntawm qhov kev xeem yog: kev hloov kho ntau yam ntawm cov zis hluav taws xob, qib kev ruaj ntseg, lub zog hluav taws xob thiab kev tiv thaiv overcurrent.
Kev tu cov txheej txheem ntawm high-power DC stabilized fais fab mov
1. Ntsuas qhov rectified tso zis voltage
Muaj ib lossis ntau pawg ntawm cov zis hluav taws xob hloov kho hauv ntau yam DC tswj cov khoom siv hluav taws xob. Yog hais tias ib qho ntawm cov kev hloov kho qhov hluav taws xob no yog qhov txawv txav, cov kev tswj fais fab yuav muaj ntau yam tsis ua haujlwm. Yog li ntawd, thaum kho dua tshiab, nws yog ib qho tsim nyog yuav tsum ntsuas thawj zaug seb qhov cuam tshuam cov zis hluav taws xob puas yog qhov qub.
2. Txheeb xyuas qhov chaw ua haujlwm ntawm lub voj voog
Yog tias cov zis hluav taws xob rectified thiab cov khoom siv hluav taws xob muaj feem xyuam yog qhov qub, qhov chaw ua haujlwm ntawm lub voj voog yuav tsum tau kuaj ntxiv. Rau lub transistor, yuav tsum muaj ib qho kev ua hauj lwm voltage ntawm nws cov collector thiab emitter, thiab lub polarity ntawm lub bias voltage ntawm lub hauv paus thiab lub emitter yuav tsum tau raws li qhov yuav tsum tau thiab xyuas kom meej tias nws ua hauj lwm nyob rau hauv lub amplification cheeb tsam.
3. Ntsuas hluav taws xob
Yog hais tias cov zis hluav taws xob rectified yog qhov qub, tab sis cov kev cai tso zis hluav taws xob tsis zoo, nws yuav tsum tau sim ntxiv seb qhov kev ua tau zoo ntawm lub raj hloov, lub tshuab hluav taws xob, thiab lwm yam yog qhov zoo, thiab seb lub capacitor yog luv luv lossis qhib- ua voj voog. Lub zog siab DC stabilized fais fab mov tuaj yeem rov qab los li qub.
4. Txheeb xyuas lub hauv paus ntsiab lus ntawm Circuit Court
Yog tias nws pom tias qhov chaw ua haujlwm voltage ntawm lub transistor yog qhov txawv txav, muaj ob txoj hauv kev: ib qho yog tias lub transistor puas lawm; lwm qhov yog tias lwm cov khoom hauv Circuit Court puas lawm. Nyob rau lub sijhawm no, nws yuav tsum ua tib zoo txheeb xyuas qhov ua rau ntawm qhov teeb meem raws li daim duab kos duab kos duab, thiab txheeb xyuas cov khoom puas thiab hloov pauv ntxiv.
5. Kev tshuaj xyuas ua ntej ntawm qhov chaw
Txhua yam khoom siv hluav taws xob DC stabilized feem ntau yog nruab nrog overload lossis luv luv-circuit tiv thaiv fuses thiab input thiab output terminals. Koj yuav tsum xub xyuas seb lub fuses puas yog cua tshuab los yog xoob, seb cov terminals puas xoob lossis luv luv rau hauv av, thiab qhov ntsuas hluav taws xob seb lub koob ntawm lub moos raug thaiv. Tom qab ntawd qhib cov ntaub ntawv npog los xyuas seb lub hwj chim transformer puas muaj ntxhiab tsw los yog pwm, thiab seb qhov kev tiv thaiv thiab lub capacitor puas raug hlawv, pwm, tawg, tawg thiab lwm yam kev puas tsuaj.
