(1) Voltage tswj tus nqi SV
Kev tswj hwm qhov ntsuas hluav taws xob yog ib qho tseem ceeb qhia txog qhov ua tau zoo ntawm qhov kev tswj xyuas hluav taws xob ntawm DC tswj fais fab mov. Nws tseem hu ua voltage regulation coefficient lossis stability coefficient. Nws sawv cev rau qib ntawm kev ruaj ntseg ntawm cov zis voltage VO ntawm DC tswj fais fab mov thaum lub input voltage VI hloov. Qhia tawm raws li feem pua ntawm cov txheeb ze hloov pauv nyob rau hauv cov tswv yim thiab cov zis voltages ntawm ib chav tsev ntawm cov zis voltage. Cov qauv ntawm cov kev cai voltage yog qhia nyob rau hauv daim duab 2-2-1.
(2) Kev cai tam sim no tus nqi SI
Cov kev cai tam sim no yog qhov tseem ceeb ntawm tus kheej qhov ntsuas qhia 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 tswj fais fab mov los txwv qhov hloov pauv ntawm cov zis hluav taws xob los ntawm kev hloov pauv ntawm cov khoom tam sim no (tso zis tam sim no) thaum lub zog nkag mus tas li. Qhov feem pua ntawm cov zis hluav taws xob hloov pauv tus nqi sawv cev rau cov kev cai tam sim no ntawm DC tswj fais fab mov. Cov qauv ntawm cov kev cai tam sim no muaj nyob rau hauv daim duab 2-2-2.
(3) Ripple rejection ratio SR
Lub ripple rejection piv qhia txog lub peev xwm ntawm DC tswj fais fab mov los suppress lub mains voltage qhia ntawm lub input davhlau ya nyob twg. Thaum cov kev tawm tswv yim thiab cov zis ntawm DC tswj cov khoom siv hluav taws xob tseem tsis hloov pauv, qhov ripple rejection piv feem ntau yog txiav txim siab los ntawm tus nqi siab tshaj-rau-nruab nrab ntawm cov input ripple voltage. Lub ncov-rau-peak piv ntawm cov zis ripple voltage feem ntau qhia hauv decibels, tab sis qee zaum nws kuj tuaj yeem qhia tau tias yog feem pua, lossis qhia ncaj qha raws li qhov piv ntawm ob.
(4) Kub 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 ntawm cov zis hluav taws xob ntawm DC tswj fais fab mov hauv qhov kev hloov pauv siab tshaj plaws ntawm kev ua haujlwm kub TI ntawm DC tswj fais fab mov (Tmin Tsawg dua lossis sib npaug rau TI Less dua lossis sib npaug rau Tmax). Cov mis ntsuas kub ruaj khov yog qhia hauv daim duab 2-2-3.
