DC tswj fais fab mov yog ib qho khoom siv uas hloov 220V lub zog zaus AC lub zog rau hauv DC voltage nrog cov zis tswj. Nws yuav tsum mus dhau plaub qhov kev sib txuas ntawm kev hloov pauv, kev hloov kho, kev lim dej, thiab kev tswj hluav taws xob.
Lub hauv paus ntsiab lus ua haujlwm ntawm plaub qhov txuas:
1. Fais fab transformer: Nws yog ib kauj ruam-down transformer, uas converts 220V AC voltage ntawm daim phiaj fais fab mus rau AC voltage uas ua tau raws li qhov xav tau thiab xa mus rau lub rectifier Circuit Court. Lub transformation ratio ntawm lub transformer yog txiav txim los ntawm lub thib ob voltage ntawm lub transformer.
2. Rectifier lim Circuit Court: Lub rectifier Circuit Court hloov AC voltage Ui rau hauv lub zog DC pulsating. Tom qab ntawd, qhov loj ripple tivthaiv yog lim tawm los ntawm lub lim lim, thiab DC voltage U1 nrog me ripple yog cov zis.
Feem ntau siv rectifier thiab lim circuits suav nrog puv-yoj rectifier thiab lim, choj rectifier thiab lim, thiab lwm yam.
3. Lim Circuit Court: Nws tuaj yeem lim tawm feem ntau ntawm AC cov khoom nyob rau hauv qhov tso zis hluav taws xob ntawm lub rectifier Circuit Court, thiaj li tau txais DC voltage zoo. Txhua lub lim capacitor C ua tau raws li RL-C=(3 ~ 5) T / 2, los yog nruab nrab T Rau lub input AC teeb liab voj voog, RL yog qhov sib npaug load kuj ntawm lub rectifier lim circuit.
4. Voltage stabilizer Circuit Court: Kev ua haujlwm ntawm qhov hluav taws xob stabilizer Circuit Court yog kom ruaj khov rau cov zis DC voltage, uas tsis hloov nrog kev hloov ntawm AC grid voltage thiab load.
Feem ntau siv integrated voltage regulators muaj xws li tsau peb-terminal voltage regulators thiab adjustable peb-terminal voltage regulators.
Feem ntau siv adjustable zoo voltage integrated voltage regulators yog CW317 (LM317) series, lawv cov zis voltage yog adjustable los ntawm 1.25V-37V, qhov yooj yim sab nraud Circuit Court Cheebtsam tsuas yog xav tau ib tug ruaj resistor thiab ib tug potentiometer.
Nws cov nti muaj qhov hloov pauv, kub dhau thiab kev tiv thaiv kev nyab xeeb, thiab qhov tso zis ntau tshaj tam sim no yog 1.5A.
