chii chinonzi ATX Power Supply

Basa reATX magetsi ndere kushandura iyo AC kuita inowanzo shandiswa DC magetsi. Ine zvinhu zvitatu zvinobuda. Kubuda kwayo kunonyanya kuyeuka uye VSB, uye inobuda inoratidza hunhu hweATX magetsi ekupa. Chinhu chikuru chemagetsi eATX ndechekuti haishandise chinja chemagetsi kudzora magetsi, asi inoshandisa + 5 VSB kugadzira mudziyo une ma switch anochinjana. Chero bedzi iyo PS-signal level ichidzorwa, inogona kuvhurwa nekudzima. simba re. PS inovhurika kana simba riri pasi pe1v, magetsi anodarika 4.5 volts anofanira kudzimwa.

Kuenzaniswa nemagetsi emagetsi, magetsi eATX haana kufanana pamutsara, mutsauko mukuru ndewekuti iyo ATX magetsi pachayo haina kukwana kana yakadzimwa, asi inochengetedza ikozvino isina simba. Panguva imwecheteyo, inowedzera chinhu chinokwidziridza ikozvino simba manejimendi, inonzi Station Pass. Iyo inobvumira iyo inoshanda sisitimu kutonga yakananga magetsi ekupa. Kuburikidza nebasa iri, vashandisi vanogona kushandura switch system vari voga, uye vanogona zvakare kuona simba retiweki manejimendi. Semuyenzaniso, komputa inogona kubatana nechiratidzo chemodemu pakombuta kuburikidza netiweki, uyezve dunhu rekutonga rinotumira iyo yakasarudzika ATX simba + 5v activation voltage, tanga kubatidza komputa, uye nekudaro ziva kutanga kure.

Iyo yakakosha dunhu reATX magetsi ekupa:

Iyo huru yekushandura dunhu reATX simba rekupa rakafanana neiyo AT simba rekupa. Iyo zvakare inotora iyo "double-tube hafu-bhiriji kumwe kufadza" sedunhu. Iyo PWM (pulse width modulation) controller inoshandisawo TL494 control chip, asi mains switch yakadzimwa.

Sezvo mains switch yakadzimwa, chero tambo yemagetsi yakabatana, pachava ne +300V DC voltage padunhu rekushandura, uye magetsi ebetsero anopawo kushanda voltage kuTL494 kugadzirira kutanga-up magetsi.
