1, Lub hauv paus ntsiab lus ntawm lub hwj chim board
Lub hwj chim board hais txog ib qho khoom siv hluav taws xob uas hloov cov tswv yim tam sim no mus rau DC voltage ruaj khov. Feem ntau, lub rooj tsavxwm fais fab suav nrog cov tswv yim thiab cov zis, nrog rau cov tswv yim txuas nrog lub zog hluav taws xob thiab cov khoom tso tawm muab DC lub zog ruaj khov rau cov khoom siv sab nraud lossis circuits. Lub hwj chim board feem ntau hloov cov tswv yim tam sim no mus rau qhov ruaj khov DC voltage los ntawm peb kauj ruam:
1. Rectification: Hloov cov input AC tam sim no mus rau ib nrab nthwv dej, puv nthwv dej, lossis peb-theem rectified DC tam sim no;
2. Kev lim dej: Los ntawm kev lim tawm ntawm qhov pulsating ntawm DC, tau txais ib qho DC voltage;
3. Voltage stabilization: Lub lim DC voltage yog stabilized nyob rau hauv ib tug tej yam voltage range los ntawm ib tug voltage stabilization Circuit Court los xyuas kom meej stability ntawm cov zis DC fais fab mov.
2, Kev ua haujlwm ntawm lub hwj chim board
Lub hwj chim boards ua lub luag haujlwm tseem ceeb hauv ntau yam khoom siv hluav taws xob. Feem ntau hais lus, lub luag haujlwm ntawm lub hwj chim boards feem ntau suav nrog peb yam hauv qab no:
1. Tiv thaiv cov khoom siv hluav taws xob: Lub rooj tsav xwm hluav taws xob tuaj yeem muab qhov ruaj khov voltage thiab tam sim no, yog li tiv thaiv cov khoom siv hluav taws xob los ntawm qhov hluav taws xob thiab qhov hloov pauv tam sim no thiab cuam tshuam;
2. Muab hluav taws xob hluav taws xob: Lub rooj tsav xwm hluav taws xob muab lub zog hluav taws xob tsim nyog rau lub cuab yeej ua haujlwm kom zoo;
3. Kev sib cuam tshuam nrog lwm cov circuits: Lub hwj chim board cuam tshuam nrog lwm cov circuits los tsim ntau yam ntawm cov khoom siv hluav taws xob, yog li kev sib koom tes ua kom tiav cov haujlwm tshwj xeeb.
Nyob rau hauv luv luv, raws li ib tug ntawm cov tseem ceeb Cheebtsam nyob rau hauv cov khoom siv hluav taws xob, lub hauv paus ntsiab lus ntawm kev ua hauj lwm thiab kev ua hauj lwm ntawm lub hwj chim board yuav tsum to taub kom meej. Tsuas yog los ntawm kev nkag siab tob txog kev ua haujlwm ntawm lub rooj tsavxwm fais fab tuaj yeem siv tau zoo dua thiab ua kom muaj kev ua haujlwm zoo ntawm cov khoom siv hluav taws xob.
