Cov yam ntxwv ntawm lub laptop charger
Chargers thiab roj teeb yog lub hauv paus ntawm lub hwj chim rau laptops thiab ib tug tsim nyog mob rau lub laptops mus ncig. Nrog rau kev sib txuas ua tiav ntawm cov khoos phis tawj thiab cov kev xav tau ntau ntxiv rau kev sib txuas lus ntawm tes thiab cov ntaub ntawv hauv ntau yam khoom siv digital, lub laptop chargers thiab roj teeb tau dhau los ua qhov chaw them nyiaj rau cov khoom siv hluav taws xob. Qhov no qhia qhov tseem ceeb ntawm lub laptop chargers thiab roj teeb. Vim tias lub laptop chargers thiab roj teeb yog kim, lawv tuaj yeem txuas ntxiv los ntawm kev saib xyuas kom zoo thiab kev saib xyuas ntawm lub laptop charger thiab roj teeb, tsis ua haujlwm kho thiab kho, thiab kho tom qab lub laptop charger thiab roj teeb ua tsis tiav. Nws lub neej expectancy tag nrho txo cov nqi peev. Raws li qhov no, tshooj no tsom mus rau lub hauv paus ntsiab lus ntawm lub laptop charger circuit uas tsim los ntawm UC3844 kev sib xyaw nti, tsom mus rau kev siv thiab kev saib xyuas kom raug thiab cov tswv yim ntawm lub laptop roj teeb.
Basic Circuit Court muaj pes tsawg leeg
Cov yam ntxwv tseem ceeb ntawm lub charger yog embodied nyob rau hauv tsib yam: Ua ntej, lub ntsiab hloov dua siab tshiab Circuit Court yog ib leeg-tube fais amplifier tsav Circuit Court muaj li ntawm ib tug MOS FET raj (2SK727) thiab kev khiav hauj lwm nyob rau hauv ib tug lub zog cia hom; thiab qhov thib ob yog tam sim no-tsav mem tes dav modulation module. UC3844 nyob rau hauv 5V thiab 12V DC fais fab mov tso zis voltage tsis zoo tawm tswv yim tswj Circuit Court, tso zis tam sim no tsis zoo tawm tswv yim tswj Circuit Court, 5V thiab -5V DC fais fab mov unbalanced output self-tiv thaiv Circuit Court thiab lub hwj chim amplifier raj tshaj-tam sim no tso zis tiv thaiv Circuit Court , thiab lwm yam. Lub raj tsav fais fab amplifier circuit outputs pulse width modulation mem tes; qhov thib peb yog muab nrog lub zoo meej tsis siv neeg tiv thaiv Circuit Court; thiab qhov thib plaub yog ib lub voj voog uas muaj cov transistor thiab RC tivthaiv. C teeb liab tsim Circuit Court, P. Lub amplitude ntawm C teeb liab yog 5V; Qhov thib tsib yog lub hwj chim amplification ntawm lub voj voog voltage mem tes los ntawm kev sib txuas ntawm high-frequency step-down transformer T1 thiab cov khoom rectification thiab filtering circuits ntawm T1 thib ob winding, muab cov av 12V thiab cov av 5V mus rau lub computer board. . DC voltage.
