Txoj kev tswj hwm hluav taws xob ntawm CC / CV cov qauv hauv DC Fais Fab?
DC cov khoom siv fais fab yog ib qho cuab yeej siv los muab cov ntaub ntawv ruaj khov, siv rau hauv cov khoom siv hluav taws xob, cov tshuab sib txuas lus, thiab tsav tsheb sib txuas lus. Hauv kev siv cov kev siv, feem ntau nws yog feem ntau tsim nyog los tswj cov zis tam sim no lossis cov zis hluav taws xob ntawm cov khoom siv hluav taws xob kom sib xws.
Cov qauv tswj hwm feem ntau rau DC Fais Fab Cov Khoom Siv yog CC (tas li tam sim no) thiab CV (tas li voltage) hom. Hauv CC hom, cov zis tam sim no los ntawm lub hwj chim muab tsis hloov pauv, thaum nyob hauv CV hom los ntawm lub hwj huam xa tawm. CC / CV hom rau kev tswj DC cov khoom siv hluav taws xob tuaj yeem siv tau siv cov thev naus laus zis sib txawv thiab cov hau kev.
Ib txoj kev siv kev siv yog los siv cov tswv yim tswj cov voj voog. Hauv txoj kev no, cov tso tawm tam sim no lossis cov zis hluav taws xob ntawm DC cov khoom siv thiab pub rov qab cov zis ntawm cov lus qhia ntawm cov lus qhia. Piv txwv li, hauv CC hom, thaum cov zis tam sim no yog qis dua cov nqi teeb tsa yuav nce cov zis ntawm lub zog hluav taws xob kom txog thaum nws nce tus nqi. Hauv CV hom, thaum cov zis hluav taws xob qis dua li cov teeb tsa tus nqi, tswj Circuit Court yuav kho cov zis hluav taws xob kom txog thaum nws nce tus nqi.
Lwm txoj hauv kev siv yog siv PWM (Pulse dav ntsuas ntsuas). PWM yog lub thev naus laus zis uas hloov cov cim qhia txog digital, kho cov zis tam sim no lossis cov zis voltage los ntawm kev tswj hwm cov teeb liab dav ntawm lub teeb liab. Hauv txoj kev no, cov tso tawm tam sim no lossis cov zis hluav taws xob ntawm lub sijhawm hloov pauv tau raug tswj hwm raws li qhov kev sib piv ntawm cov txiaj ntsig lossis cov zis hluav taws xob. Piv txwv li, hauv CC hom, thaum cov zis tam sim no qis dua cov nqi uas tau hloov, yog li nce cov zis tawm tam sim no kom txog thaum nws nce tus nqi. Hauv CV hom, thaum cov zis hluav taws xob qis dua li cov teeb tsa tus nqi, yog li nce cov zis voltage kom txog thaum nws mus txog ntawm cov nqi teeb.
Ntxiv rau cov kev tswj no feem ntau, muaj lwm yam tswv yim uas tuaj yeem siv los tswj CC / CV hom ntawm DC cov khoom siv fais fab. Piv txwv li, thev naus laus zis tam sim no tuaj yeem siv los tiv thaiv lub zog hluav taws xob thaum cov zis tam sim no tau mus txog tus nqi uas tau ua tiav, yog li ua tiav tas li tswj tau tas mus li. Lub tshuab muag hloov tau kuj tseem siv tau los txhim kho kev ua haujlwm thiab kev teb kom ceev ntawm DC cov khoom siv fais fab. Ib qho ntxiv, cov teeb liab kos npe (DSPs) lossis microcontrollers tuaj yeem siv kom ua tiav cov khoom siv hluav taws xob ntau, tiag tiag}} kev soj ntsuam, thiab kev tiv thaiv.
