Cov khoom tseem ceeb ntawm cov hlau lead -acid roj teeb charger

A lead-acid roj teeb charger feem ntau muaj plaub ntu: input circuit, fais fab hloov hluav taws xob, tswj Circuit Court, thiab tiv thaiv Circuit Court. Cov Cheebtsam no ua haujlwm ua ke kom muaj kev nyab xeeb thiab siv tau zoo ntawm lub roj teeb.

Input Circuit: "Thawj Kab Kev Tiv Thaiv" rau Hluav Taws Xob Hluav Taws Xob Lub luag haujlwm rau kev qhia thiab pib ua AC lub zog hluav taws xob, feem ntau suav nrog:

Fuse: Tiv thaiv overcurrent puas tsuaj rau cov khoom siv sab hauv, ua haujlwm raws li kev nyab xeeb yooj yim.

Varisetter: Absorbs surge voltage los ntawm lub mains, tiv thaiv tom qab circuits los ntawm xob laim ntaus los yog voltage spikes.

NTC Thermistor: Tshem tawm qhov hluav taws xob tam sim no thaum pib, tiv thaiv kev cuam tshuam ntawm cov khoom xws li tus choj rectifier.

EMI Filter Circuit (xws li hom - hom inductor thiab kev nyab xeeb capacitor): Lim tawm siab - zaus cuam tshuam, txhim kho electromagnetic compatibility (EMC).

Rectifier Choj: Hloov AC lub zog rau hauv lub zog DC, npaj rau kev hloov pauv tom ntej.

Tswj Circuit: "Lub hlwb ntse" ntawm cov txheej txheem them nyiaj

Microcontroller lossis IC nti tshwj xeeb (piv txwv li, UC3886, PI SC1060E): Ua haujlwm peb -theem ntse charging (pre-them nqi, tsis tu ncua tam sim no, ntab nqi), cia li txheeb xyuas lub roj teeb voltage thiab hloov hom.

Voltage / tam sim no tawm tswv yim Circuit Court: Saib xyuas cov xwm txheej hauv lub sijhawm, pub lub teeb liab rov qab mus rau lub davhlau ya nyob twg tswj los ntawm optocoupler (xws li PC817), tsim qhov kaw - txoj cai voj.

LED qhov taw qhia: Qhia txog kev them nyiaj siv cov xim sib txawv (xws li, lub teeb liab rau kev them nyiaj, lub teeb ntsuab rau kev them tag nrho).
