DC Voltage Regulator Technical Specification
DC tswj cov khoom siv hluav taws xob muaj peev xwm muab faib ua ob pawg: ib qho yog cov cim qhia, qhia txog cov yam ntxwv ntawm DC tswj fais fab mov, xws li input voltage, tso zis voltage, tso zis tam sim no, tso zis voltage hloov ntau yam; Lwm qhov yog qhov ntsuas tau zoo, qhia txog qhov ua tau zoo thiab qhov tsis muaj zog ntawm DC tswj fais fab mov, suav nrog kev ruaj ntseg, sib npaug tsis kam (tso tawm tsis kam), ripple voltage thiab kub coefficient thiab lwm yam.
1, cov yam ntxwv ntawm cov ntsuas
(1) Cov zis voltage ntau
DC tswj fais fab mov kev khiav hauj lwm nyob rau hauv txoj kab nrog cov zis voltage ntau yam uas yuav ua hauj lwm ib txwm. Lub sab sauv txwv ntawm qhov ntsuas no yog teev los ntawm qhov siab tshaj plaws input voltage thiab yam tsawg kawg nkaus input - output voltage sib txawv, thaum nws qis txwv yog txiav txim los ntawm tus nqi siv voltage hauv DC tswj fais fab mov.
(2) Qhov siab tshaj plaws input-output voltage sib txawv
Qhov Performance index no qhia txog qhov sib txawv ntawm qhov siab tshaj plaws input-output voltage tso cai raws li kev ua haujlwm ib txwm muaj ntawm DC tswj fais fab mov, thiab nws cov nqi feem ntau yog nyob ntawm qhov ntsuas qhov ntsuas ntawm qhov hloov pauv hloov hauv DC tswj fais fab mov.
(3) Yam tsawg kawg nkaus input-output voltage sib txawv
Qhov ntsuas no qhia qhov tsawg kawg nkaus input-tso tawm voltage qhov sib txawv uas yuav tsum tau ua kom ntseeg tau qhov kev ua haujlwm zoo ntawm DC fais fab mov.
(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, ntsuas qhov 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 rau 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 qhov fluctuation ntawm cov zis voltage ntawm inhibition ntawm lub peev xwm los hloov lub load tam sim no nyob rau hauv cov kev cai ntawm lub load tam sim no. hloov, feem ntau yog lub tsev tso zis voltage nyob rau hauv cov zis voltage ntawm cov zis voltage hloov tus nqi ntawm cov feem pua ntawm cov DC tswj fais fab mov los qhia qhov 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 cov zis ripple voltage ncov-rau-peak piv, feem ntau qhia hauv decibels, tab sis qee zaum kuj tuaj yeem qhia hauv feem pua! los yog qhia ncaj qha 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. Temperature stability yog qhia hauv daim duab 2-2-3.
3, txwv ntsuas
(1) Qhov siab tshaj plaws input voltage
Yog qhov siab tshaj plaws input voltage los xyuas kom meej kev nyab xeeb ntawm DC tswj fais fab mov.
(2) Qhov siab tshaj plaws tso zis tam sim no
Yog qhov siab tshaj plaws tso zis tam sim no tso cai rau kev ua haujlwm ruaj ntseg ntawm tus tswj hwm.
