Ib qho yog tus yam ntxwv Performance index uas qhia txog cov yam ntxwv sab hauv ntawm qhov hluav taws xob-stabilized DC fais fab mov, xws li input voltage, output voltage, tso zis tam sim no, thiab lwm yam, thiab cov zis voltage teeb tsa ntau yam; Lwm qhov yog qhov ntsuas qhov zoo uas qhia txog qhov zoo thiab qhov tsis zoo ntawm qhov hluav taws xob ruaj khov DC fais fab mov, xws li ruaj khov Resistance, sib npaug sab hauv tsis kam (tso tawm tsis kam), ripple voltage, kub coefficient.
1. Cov yam ntxwv ntsuas
(1) Cov zis voltage ntau
Nyob ntawm qhov kev ua haujlwm ntawm DC regulator, cov zis hluav taws xob ntau tuaj yeem ua haujlwm ib txwm. Lub sab sauv txwv ntawm qhov ntsuas no yog txiav txim los ntawm qhov sib txawv ntawm qhov siab tshaj plaws input voltage thiab qhov tsawg kawg nkaus input thiab output voltage, thiab qhov qis qis yog txiav txim siab los ntawm qhov voltage hauv paus ntawm DC fais fab mov.
(2) Qhov siab tshaj qhov sib txawv ntawm cov tswv yim thiab cov zis voltage
Qhov ntsuas no piav qhia txog qhov sib txawv ntawm qhov sib txawv ntawm qhov siab tshaj plaws input voltage thiab cov zis voltage ntawm DC regulator nyob rau hauv ib txwm ua hauj lwm tej yam kev mob, thiab nws cov nqi feem ntau yog nyob ntawm qhov voltage ratio ntawm voltage regulator transistor nyob rau hauv lub DC regulator.
(3) Yam tsawg kawg nkaus input thiab output voltage sib txawv
Qhov ntsuas no piav qhia qhov tsawg kawg nkaus qhov sib txawv ntawm qhov kev tawm tswv yim thiab cov zis los xyuas kom meej qhov kev ua haujlwm ntawm DC regulator.
(4) Tso zis load tam sim no ntau yam
Cov zis load tam sim no ntau yam, tseem hu ua qhov tso zis ntau yam tam sim no, nyob rau hauv qhov ntau, DC fais fab mov yuav tsum muaj peev xwm ua tau raws li qhov ntsuas tau teev tseg hauv daim ntawv qhia tshwj xeeb.
2. Cov ntsuas zoo
(1) Voltage tswj ceev SV
Stabilization ceev yog ib qho tseem ceeb Performance index los piav qhia txog cov yam ntxwv stability ntawm DC fais fab mov, kuj hu ua voltage stability coefficient los yog stability coefficient, nws qhia qhov stability ntawm cov zis voltage VO ntawm lub input DC fais fab mov thaum lub input voltage VI hloov, feem ntau cov input. thiab cov zis voltages yog nruab nrab ntawm kwv yees feem pua ntawm kev hloov pauv hauv cov khoom siv hluav taws xob tso zis hluav taws xob
(2) Tam sim no kho tus nqi Si
Tus nqi kho tam sim no yog qhov kev hloov kho tus kheej tseem ceeb uas cuam tshuam txog lub peev xwm thauj khoom ntawm DC fais fab mov, tseem hu ua kev ruaj ntseg coefficient tam sim no. Nws qhia tau hais tias muaj peev xwm ntawm DC lub zog hluav taws xob txhawm rau txhawm rau txo qhov tso tawm qhov hluav taws xob hloov pauv los ntawm kev hloov pauv ntawm cov khoom siv tam sim no (tsim tawm tam sim no) thaum lub zog nkag mus tas li.
Nyob rau hauv ib qho kev hloov pauv tam sim no, qhov kev ruaj ntseg tam sim no ntawm DC fais fab mov feem ntau yog qhia raws li feem pua qis dua qhov tso zis hluav taws xob hloov ntawm lub cuab yeej.
(3) Lub ripple rejection piv yog ntau dua SR
Tus qauv yoj yoj kev sib piv qhia txog lub peev xwm ntawm DC lub zog hluav taws xob txhawm rau txhawm rau qhov hluav taws xob input ntawm lub tswv yim. Thaum cov kev tawm tswv yim thiab cov khoom tso tawm ntawm kev tswj hwm DC lub zog hluav taws xob tau khaws cia tas mus li, qhov kev ntxhib los mos yoj qhov cuam tshuam feem ntau yog qhia raws li qhov piv ntawm tus nqi ncov ntawm qhov kev ntxhib los mos yoj input voltage rau lub ncov tus nqi ntawm qhov kev ntxhib los mos yoj tawm voltage, feem ntau qhia. hauv decibels, tab sis qee zaum kuj qhia raws li feem pua lossis Qhia ncaj qha raws li qhov piv ntawm ob.
(4) Kub stability K
Qhov ntsuas kub ruaj khov ntawm kev sib xyaw DC tswj fais fab yog hais txog qhov sib txawv ntawm qhov feem pua ntawm cov zis hluav taws xob ntawm DC tswj fais fab hauv qhov siab tshaj plaws kev khiav hauj lwm kub ntau Ti ntawm DC fais fab mov.
3. Upper limit voltage thiab tam sim no
(1) Qhov siab tshaj plaws input voltage.
Qhov no yog qhov siab tshaj plaws input voltage rau kev nyab xeeb ntawm DC fais fab mov.
(2) Cov zis siab tshaj plaws tam sim no.
Qhov no yog qhov siab tshaj plaws tso zis tam sim no tso cai los ntawm kev tswj fais fab kev lag luam kom muaj kev nyab xeeb.
