Indima yonikezelo lwamandla e-ATX kukuguqula i-AC ibe yi-DC esetyenziswa rhoqo. Ineziphumo ezintathu. Imveliso yayo ikakhulu inkumbulo kunye ne-VSB, kwaye imveliso ibonisa iimpawu zonikezelo lwamandla e-ATX. Eyona nto iphambili yonikezelo lwamandla e-ATX kukuba ayisebenzisi isitshixo samandla emveli ukulawula unikezelo lwamandla, kodwa isebenzisa + 5 VSB ukwenza isixhobo esineeswitshi ezitshintshanayo. Ngethuba nje inqanaba le-PS-signal lilawulwa, linokuvulwa kwaye livaliwe. amandla e. I-PS ivula xa amandla engaphantsi kwe-1v, umbane ongaphezu kwe-4.5 volts kufuneka ucinywe.
Xa kuthelekiswa nonikezelo lwamandla, unikezelo lwamandla lwe-ATX alufani kumgca, umahluko omkhulu kukuba umbane we-ATX ngokwawo awugqibekanga xa ucinyiwe, kodwa ugcina umbane obuthathaka. Kwangaxeshanye, yongeza into enika amandla ulawulo lwamandla lwangoku, olubizwa ngokuba yiSitishi sokudlula. Ivumela inkqubo yokusebenza ukulawula unikezelo lwamandla ngokuthe ngqo. Ngalo msebenzi, abasebenzisi banokutshintsha inkqubo yokutshintsha ngokwabo, kwaye banokuqonda amandla olawulo lwenethiwekhi. Ngokomzekelo, ikhomputha inokudibanisa kwisignali yemodem kwikhompyutheni ngokusebenzisa inethiwekhi, kwaye emva koko isiphaluka solawulo siya kuthumela i-ATX eyodwa yamandla + i-5v yokuvuselela i-voltage, iqalise ukuvula ikhompyutha, kwaye ngaloo ndlela uqaphele ukuqala okude.
Undoqo wesekethe ye-ATX yobonelelo lwamandla:
Isiphaluka esiphambili sokuguqula umbane we-ATX ufana ne-AT. Ikwamkele i-"double-tube half-bridge other excitation". Umlawuli we-PWM (i-pulse width modulation) usebenzisa i-chip ye-TL494 yokulawula, kodwa i-mains switch switch iyacinywa.
Ekubeni i-mains switch icinyiwe, nje ukuba intambo yamandla ixhunyiwe, kuya kubakho i- +300V DC yombane kwi-conversion circuit, kwaye umbane oncedisayo unika amandla ombane osebenzayo kwi-TL494 ukulungiselela ukunikezelwa kwamandla okuqalisa.
