Technical specifications ntawm DC voltage stabilized fais fab mov
1, Cov yam ntxwv index
(1) Cov zis voltage ntau
Nyob rau hauv txoj kab nrog DC tswj fais fab kev khiav hauj lwm tej yam kev mob, cov zis voltage ntau yam uas yuav ua hauj lwm ib txwm. Cov kev txwv sab saud ntawm qhov ntsuas no tau teev tseg los ntawm * qhov loj input voltage thiab * cov tswv yim me me - qhov hluav taws xob tawm qhov sib txawv, thaum nws qhov txwv qis yog txiav txim siab los ntawm DC tswj fais fab mov sab hauv siv voltage tus nqi.
(2) Qhov siab tshaj plaws input-output voltage sib txawv
Qhov ntsuas no qhia txog DC tswj fais fab mov nyob rau hauv ib txwm ua hauj lwm tej yam kev mob, tso cai * loj input - output voltage sib txawv ntawm qhov tseem ceeb nyob rau hauv lub DC tswj fais fab mov sab hauv hloov transistor voltage withstand indicators.
(3) Yam tsawg kawg nkaus input - output voltage sib txawv
Qhov ntsuas no qhia txog DC tswj fais fab mov kom ntseeg tau tias kev ua haujlwm ib txwm muaj, qhov yuav tsum tau * me me input - tso zis voltage sib txawv.
(4) Tso zis load tam sim no ntau yam
Cov zis load tam sim no kuj tseem hu ua qhov tso zis ntau yam tam sim no, nyob rau hauv qhov tam sim no ntau yam, DC tswj fais fab mov yuav tsum muaj peev xwm ua kom tau raws li qhov ntsuas tau muab rau hauv qhov kev qhia tshwj xeeb.
2, Kev ntsuas zoo
(1) Voltage tswj tus nqi SV
Kev hloov pauv hluav taws xob yog tus cwj pwm los ntawm DC tswj fais fab mov voltage regulator kev ua tau zoo ntawm cov ntsuas tseem ceeb, tseem hu ua qhov ntsuas hluav taws xob lossis qhov ruaj khov, uas qhia txog thaum lub tswv yim voltage VI hloov hauv DC tswj fais fab mov tso zis voltage VO ruaj khov qib ntawm cov tswv yim. voltage feem ntau yog qhia raws li ib chav tsev ntawm cov zis voltage nyob rau hauv lub input thiab output voltages ntawm tus txheeb ze hloov nyob rau hauv feem pua. Cov qauv kev tswj hwm tus nqi hluav taws xob muaj nyob hauv daim duab 2-2-1.
(2) Kev hloov kho tam sim no SI
Kev hloov pauv tam sim no yog qhov ntsuas tus kheej tseem ceeb los cuam tshuam lub peev xwm ntawm DC tswj fais fab mov, tseem hu ua qhov kev ruaj ntseg tam sim no. Nws characterizes thaum lub input voltage tsis hloov, DC tswj fais fab mov vim lub load tam sim no (tsim tawm tam sim no) hloov los ntawm cov zis voltage fluctuation suppression muaj peev xwm, nyob rau hauv lub teev load tam sim no hloov nyob rau hauv tej yam kev mob, feem ntau yog mus rau lub tsev tso zis voltage nyob rau hauv lub tso zis voltage hloov nyob rau hauv feem pua ntawm tus nqi ntawm DC tswj fais fab mov tam sim no hloov tus nqi. Cov qauv hloov pauv tam sim no muaj nyob hauv daim duab 2-2-2.
(3) Ripple rejection ratio SR
Ripple rejection ratio qhia txog DC tswj fais fab mov ntawm sab tswv yim ntawm kev qhia txog kev siv hluav taws xob hluav taws xob hluav taws xob, thaum DC tswj cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tsis hloov pauv, ripple rejection ratio feem ntau input ripple voltage ncov-rau-peak. thiab tso zis ripple voltage ncov-rau-peak piv qhia nyob rau hauv decibels, feem ntau hais nyob rau hauv decibels, tab sis tej zaum yuav siv tau raws li ib feem pua ntawm tus nqi ntawm ob, los yog ncaj qha qhia raws li qhov piv ntawm ob.
(4) kub stability K
Integrated DC tswj fais fab mov kub stability yog raws li qhov teev DC tswj fais fab mov kev khiav hauj lwm kub Ti siab tshaj plaws hloov ntau yam (Tmin Tsawg tshaj los yog sib npaug rau Ti Tsawg tshaj los yog sib npaug rau Tmax) DC tswj fais fab mov tso zis voltage ntawm tus txheeb ze hloov nyob rau hauv feem pua. tus nqi.
