Cov thev naus laus zis tseem ceeb rau hluav taws xob maus taus ceev Chargers

Niaj hnub nimno fais fab maus taus chargers feem ntau siv lub flyback switching power supply architecture, integrating microcontroller rau ntse tswj. Piv txwv li, lub chaw muag khoom muaj 72V / 5A charger ntiav EG1253 PWM maub los (los ntawm Yijing Micro) thiab WMK26N65C4 hloov transistor (los ntawm Wayon) ntawm thawj sab, thaum siv ceev ceev - rov qab diodes rau rectification ntawm sab tso zis. Lub MCU sab hauv yog tswj hwm qhov peb -theem them cov txheej txheem thiab saib xyuas cov xwm txheej hauv lub cev. Txhawm rau kom ntseeg tau tias muaj kev ntseeg siab, cov chargers no feem ntau ua ib feem ntawm lub lauj kaub los txhim kho cov dej noo thiab lub zog ntawm lub zog, nrog rau kev ua kom txias los ntawm kev sib xyaw ntawm cov heatsinks thiab lub kiv cua sab hauv. Kev tiv thaiv cua sov yog ua tiav los ntawm qhov tiag -lub sijhawm ntsuas kub sab hauv los ntawm cov thermistor kom tiv thaiv kom tsis txhob muaj cua sov. Cov zis txuas feem ntau ua raws li Txoj Cai Tshiab Hauv Tebchaws thiab suav nrog cov qauv tsim lub cev uas tiv thaiv kev sib txuas rov qab polarity.
