Ukushintshwa kwemisebe amandla kukhompyutha nezelani kumadivayisi ahlukahlukene

Ikhompyutha lisebenzela thina eminyakeni, abe umngane wangempela umndeni, futhi lapho kuba akusebenzi noma ngendlela engenathemba siphukile, Uyazisola ngakho ukukuthwala yokulahla. Kodwa zikhona izingxenye ukuthi kungase kudonse isikhathi eside ekhaya. Lokhu cooler eminingi processor ukushisa zigezwa khona, futhi ngisho emzimbeni. Kodwa into eyigugu kakhulu - lokhu PSU. Iyunithi enikeza amandla, sibonga amandla ehloniphekile nge Ubukhulu encane, iyindawo ekahle zonke izinhlobo ukuthuthukiswa. ukuguqulwa kwakhe - akuyona umsebenzi onzima kangaka.

Ukushintshwa kwemisebe amandla kukhompyutha Iyunithi enikeza evamile umthombo voltage

Udinga ukunquma onjani ukuvimba ugesi yekhompyutha yakho, i-AT noma ATX. Njengomthetho, lokhu kuboniswa phezu kwezindlu. Pulsed ugesi ukusebenza kuphela ngaphansi komthwalo. Kodwa ATX uhlobo amandla Iyunithi enikeza ivumela kuvalwe izintambo eziluhlaza nezimnyama ukulubonisa eyayenziwe. Ngakho, yokuxhuma umthwalo (ye-AT) noma ukuvala iziphetho ezidingekayo (i ATC), ungakwazi ukusebenzisa fan. Okuphuma 5, futhi volts 12. Ubuningi okukhipha zamanje kuncike amandla Iyunithi enikeza. Ngezinye Watts 200, ngesikhathi pyativoltovom okukhipha zamanje ongafinyelela oda 20a ukuze 12b - mayelana 8a. Ngakho akukho zindleko ezengeziwe ungakwazi ukujabulela omuhle wokudla ngokuhle okukhipha izici.

Ukushintshwa kwemisebe amandla kukhompyutha supply kuya ngokomthetho umthombo voltage

Yiba PD ekhaya noma emsebenzini kuyinto ngempela elula. Shintsha iyunithi ejwayelekile nzima. Udinga ukushintsha resistors ezimbalwa futhi vypayat mpintsha. Lapho lesi silinganiso voltage kungase kushintshwe kusuka volts 0 kuya ku-20. Ngokwemvelo, imisinga bazosala olinganise yasekuqaleni. Uma aneliseke voltage esiphezulu 12V kwanele setha okukhipha thyristor voltage yayo Regulator. Isifunda Umlawuli silula. Ngesikhathi esifanayo kuyokusiza ukuze kugwemeke ukuphazamiseka engxenyeni sangaphakathi iyunithi ikhompyutha.

Ukushintshwa kwemisebe amandla kukhompyutha supply imoto ishaja

Isimiso akuyona ngokungafani ngokomthetho ugesi. Kuphela kuyatuseka ukushintsha diodes Schottky ukuba namandla kakhulu. Ishaja emandleni nikeza ikhompyutha enezinto eziningi ngebuhle nebubi. Izinzuzo ngokuyinhloko zihlanganisa usayizi amancane nesisindo ukukhanya. inkumbulo transformer sinzima kakhulu futhi kunzima ukusebenzisa. Ububi bayo futhi abalulekile: the criticality we isekhethi futhi polarity reverse.

Yiqiniso, lokhu criticality is ebonwe idivayisi transformer, kodwa ukwehluleka okukhipha AC ishayela iyunithi nge voltage ka 220V izimisele ibhethri. Kunzima ukucabanga ngemiphumela lokhu wonke amadivaysi nabantu eziseduze. Isicelo emandleni Ukuvikelwa izimpahla ukuzixazulula le nkinga.

Ngaphambi kokusebenzisa leli thuluzi ukushaja, sina Phatha ukuba yokukhiqiza circuit Ukuvikelwa. Ikakhulukazi ngoba kukhona izinhlobonhlobo eziningi.

Ngakho, musa ukusheshe bachithe izingxenye kudivayisi ubudala. Ukushintshwa kwemisebe amandla kukhompyutha supply uyonika ukuphila yesibili kuye. Lapho ukusebenza BP, khumbula ukuthi ibhodi salo njalo ngaphansi 220V, futhi simele usongo ofayo. Sebenzisa efanele izinyathelo zokuphepha lapho esebenza kagesi.
