Kodi mukudziwa chomwe chimayambitsa kutayikira kwa magetsi pamagalimoto amagetsi amagetsi?

Kuthamangitsa galimoto yamagetsimulu kutayikira panopa amagawidwa mu mitundu inayi, monga: semiconductor chigawo kutayikira panopa, mphamvu kutayikira panopa, capacitor kutayikira panopa ndi fyuluta kutayikira panopa.

1. Kutaya kwatsopano kwa zigawo za semiconductor

Pakalipano yaying'ono kwambiri yomwe imadutsa pamzere wa PN ikadulidwa.DS imakondera kutsogolo, GS imakondera, ndipo njira ya conductive ikatsegulidwa, pakali pano ikuyenda kuchokera ku D kupita ku S. masiku ano DS.

2. Mphamvu kutayikira panopa

Kuti muchepetse kusokoneza kwa magetsi osinthira, malinga ndi muyezo wadziko lonse, dera la EMI fyuluta liyenera kuperekedwa.Chifukwa cha ubale wa dera la EMI, pali kawotchi kakang'ono pansi pambuyo poti mphamvu yosinthira ikulumikizidwa ndi mains, yomwe ndi kutayikira pano.Ngati sichinakhazikike, chipolopolo cha kompyuta chidzakhala ndi mphamvu ya 110 volts pansi, ndipo idzamva dzanzi mukachigwira ndi manja anu, ndipo chidzakhudzanso ntchito ya kompyuta.

3. Capacitor kutayikira panopa

Sing'anga ya capacitor singakhale yosayendetsa;pamene magetsi a DC amagwiritsidwa ntchito pa capacitor, capacitor idzakhala ndi mpweya wotuluka.Ngati mpweya wotuluka ndi waukulu kwambiri, capacitor idzawonongeka ndi kutentha.Kuphatikiza pa ma electrolytic capacitor, kutayikira kwa ma capacitor ena ndikocheperako kwambiri, kotero gawo la kukana kwa insulation limagwiritsidwa ntchito kuyimira ntchito yawo yotsekereza, pomwe ma electrolytic capacitors ali ndi kutayikira kwakukulu, kotero kutayikira kwapano kumagwiritsidwa ntchito kuyimira ntchito yawo yotsekera (molingana ku luso).Pamene magetsi ogwiritsira ntchito DC amagwiritsidwa ntchito pa capacitor, zidzawona kuti kusintha kwa magetsi kumayamba kukhala kwakukulu, ndipo kumachepa ndi nthawi.Ikafika pamtengo wina wake womalizira, imafika pamlingo wokhazikika.Mtengo womalizawu umatchedwa leakage current.i=kcu(ua);pomwe k ndiko kutulutsa kosalekeza, gawoli ndi μa(v:μf)

4. Sefa kutayikira panopa

Kutayikira kwaposachedwa kwa fyuluta yamagetsi kumatanthauzidwa ngati: yapano kuchokera panyumba yosefera mpaka kumapeto kwa mzere wolowera wa AC pansi pa voteji ya AC.Ngati madoko onse a fyuluta ali otsekedwa kwathunthu ndi nyumbayo, mtengo wa kutayikira panopa makamaka zimadalira kutayikira panopa wa wamba mode capacitor CY, ndiye makamaka zimadalira mphamvu ya CY.Chifukwa cha kukula kwa kutayikira kwa fyuluta, komwe kumakhudza chitetezo chaumwini, mayiko onse padziko lapansi ali ndi miyezo yolimba ya izo.Kwa magetsi a 220V/50Hz AC, kutayikira kwa fyuluta yaphokoso nthawi zambiri kumafunika kukhala osachepera 1mA.
