Txoj kev ntsuas tseem ceeb ntawm DC tswj fais fab mov
1) Nws yuav tsum tau ntsuas nyob rau hauv ib lub sij hawm ncua ntawm 1.5 vib nas this mus rau 11.5 vib nas this tom qab kev tswj load tiav.
2) Ntsuas thaum qhov hluav taws xob tso rau ntawm 198 volts, 220 volts, thiab 242 volts feem.
3) Txoj kev ntsuas rau kev tswj fais fab mov:
4) Kev ntsuas qhov ntsuas hluav taws xob tas li tam sim no
5) Thaum cov nyhuv load thiab ntsuas lub sij hawm thiab random offset cuam tshuam rau ib leeg, lawv yuav tsum tau ntsuas nyias.
6) Kev ntsuas ntawm cov nyhuv load yog qhov ntsuas ntawm qhov hloov pauv ntawm qhov hluav taws xob lossis qhov tso tawm tam sim no ruaj khov vim qhov hloov pauv ntawm cov khoom thauj nkaus xwb.
7) Kev ntsuas lub sij hawm thiab qhov sib txawv ntawm qhov sib txawv yog qhov ntsuas ntawm qhov hloov pauv tsis tu ncua (yav tas los hu ua ripple thiab suab nrov) nyob rau hauv qhov chaw ruaj khov ntawm qhov hluav taws xob lossis tam sim no. Qhov ntsuas zaus ntau yog: 10Hz ~ 10MHz, thiab ib qho chaw hauv av yuav tsum tau siv thaum ntsuas kom tsis txhob ntsuas qhov yuam kev.
Qhov Performance index ntawm DC tswj fais fab mov
1) Kev hloov pauv voltage SV. Tus nqi hloov pauv voltage yog qhov ntsuas tseem ceeb rau tus yam ntxwv zoo ntawm DC stabilized voltage fais fab mov, tseem hu ua voltage regulation coefficient los yog stability coefficient, uas characterizes lub degree ntawm stability ntawm cov zis voltage VO ntawm DC stabilized fais fab mov thaum cov input voltage VI hloov, feem ntau nyob rau hauv Qhia raws li ib feem pua ntawm cov txheeb ze hloov nyob rau hauv input thiab output voltages ib unit output voltage. Voltage tswj formula.
(2) Kev hloov kho tam sim no SI. Qhov kev hloov kho tam sim no yog qhov ntsuas tus kheej tseem ceeb uas cuam tshuam txog lub peev xwm ntawm DC tswj fais fab mov, tseem hu ua qhov kev ruaj ntseg coefficient tam sim no. Nws characterizes lub peev xwm ntawm DC stabilized fais fab mov los suppress qhov hloov pauv ntawm cov zis voltage tshwm sim los ntawm kev hloov ntawm lub load tam sim no (tsim tawm tam sim no) thaum lub input voltage yog tas li. Nyob rau hauv cov xwm txheej ntawm qhov kev hloov pauv tam sim no, nws feem ntau yog qhia raws li chav tso zis voltage Qhov feem pua ntawm cov zis hluav taws xob hloov pauv tus nqi yog siv los sawv cev rau qhov hloov pauv tam sim no ntawm DC stabilized fais fab mov. Cov qauv kev cai tam sim no. .
(3) Ripple rejection ratio SR. Lub ripple rejection piv qhia txog lub peev xwm ntawm DC stabilized fais fab mov los suppress lub mains voltage qhia los ntawm lub input davhlau ya nyob twg. Thaum cov tswv yim thiab cov zis ntawm DC stabilized fais fab mov tseem tsis hloov pauv, ripple rejection piv feem ntau qhia raws li cov tswv yim ripple Qhov piv ntawm qhov siab tshaj plaws-rau-peak tus nqi ntawm qhov voltage mus rau lub ncov-rau-peak tus nqi ntawm cov zis ripple voltage feem ntau qhia nyob rau hauv decibels, tab sis tej zaum nws kuj yuav qhia tau nyob rau hauv ib tug feem pua, los yog qhia ncaj qha los ntawm tus piv ntawm ob.
(4) Temperature stability K. Qhov kub thiab txias ntawm kev sib xyaw DC tswj fais fab mov yog qhov feem pua tus nqi ntawm cov txheeb ze hloov pauv hauv cov zis hluav taws xob ntawm DC tswj fais fab hauv qhov teev ntau qhov sib txawv ntawm qhov kev khiav hauj lwm kub Ti ntawm DC tswj. fais fab mov (Tmin Tsawg dua lossis sib npaug Ti Tsawg dua lossis sib npaug rau Tmax). Temperature Stability Formula.
