Puv-Ib Vuag thiab Ib Nrab Qav Ua Si

Rectification cov kev hloov pauv mus hloov AC (Kev Hloov Tam Sim No) mus rau DC (Kev Ncaj Qha Tam Sim No) suav nrog kev kho tag nrho thiab ib nthwv dej ib nrab. Hauv ob qho xwm txheej no, kev ua kom pom tseeb yog ua los ntawm kev siv tus yam ntxwv uas tam sim no ntws nkaus xwb hauv cov kev taw qhia zoo nyob rau hauv ib qho diode.

Puv nthwv cov khoom siv kho cov teeb meem tsis zoo ntawm qhov ntsuas hluav taws xob mus rau qhov hluav taws xob zoo, tom qab ntawd hloov nws mus rau DC (mem tes tam sim no) siv cov diode choj teeb tsa. Hauv kev sib piv, ib nrab nthwv dej rectification tsuas tshem tawm qhov tsis zoo voltage feem siv ib zaug xwb ua ntej hloov mus rau DC.
Tom qab ntawd, qhov chaw nthwv dej yog smoothed los ntawm them / tawm lub zog, ua rau lub teeb liab DC huv.
Los ntawm qhov no, nws tuaj yeem hais tias tag nrho-nthwv dej rectification yog cov qauv ua tau zoo dua li ib nrab nthwv dej rectification txij li tag nrho cov qauv siv.
Tsis tas li, qhov hluav taws xob tsis sib xws uas tshwm tom qab kev zom zaws yuav sib txawv nyob ntawm qhov muaj peev xwm ntawm tus capacitor no thiab lub nra.
Muab tib lub peev xwm thiab thauj khoom, sib nqus voltage yog me me nrog tag nrho-nthwv dej rectification dua haif-wave rectification. Ntawm chav kawm nws mus yam tsis tau hais tias tus me dua lub zog ripple qhov hluav taws xob zoo dua kev ruaj khov.
