Mphamvu yamagetsi ya benchtop kuti igwire bwino ntchito

Kuti magetsi a benchtop agwire bwino ntchito, ndikofunikira kumvetsetsa mfundo zake zoyambira. Mphamvu ya benchtop imasintha mphamvu yolowera ya AC kuchokera pakhoma kupita ku mphamvu ya DC yomwe imagwiritsidwa ntchito kupatsa mphamvu zigawo zosiyanasiyana mkati mwa kompyuta. Nthawi zambiri imagwira ntchito pa single-phase AC input ndipo imapereka ma voltages angapo a DC output, monga +12V, -12V, +5V, ndi +3.3V.

Kuti asinthe mphamvu yolowera ya AC kukhala mphamvu ya DC, magetsi operekedwa ndi benchtop amagwiritsa ntchito transformer kuti asinthe mphamvu yolowera ya AC yamagetsi okwera komanso otsika kukhala chizindikiro cha AC chamagetsi otsika komanso chamagetsi apamwamba. Chizindikiro cha AC ichi chimakonzedwa pogwiritsa ntchito ma diode, omwe amasintha chizindikiro cha AC kukhala mphamvu ya DC yothamanga.

Kuti magetsi a DC azitha kuyenda bwino, magetsi a pakompyuta amagwiritsa ntchito ma capacitor omwe amasunga mphamvu yochulukirapo ndikuyitulutsa nthawi yamagetsi otsika, zomwe zimapangitsa kuti magetsi otulutsa a DC akhale olimba. Magetsi a DC amayendetsedwa pogwiritsa ntchito magetsi owongolera kuti atsimikizire kuti amakhalabe mkati mwa mphamvu zomwe zimaloleza, zomwe zimateteza kuwonongeka kwa zigawo. Chitetezo chosiyanasiyana, monga chitetezo cha magetsi ochulukirapo, chitetezo cha magetsi ochulukirapo, ndi chitetezo cha magetsi afupiafupi, chimapangidwanso m'magetsi a pakompyuta kuti apewe kuwonongeka kwa zigawo ngati pali zolakwika.

Kumvetsetsa mfundo zoyambira za magetsi apakompyuta kungathandize kusankha magetsi oyenera a kompyuta ndikuwonetsetsa kuti ikugwira ntchito bwino.

M'nkhaniyi, tikambirana mfundo zoyambira za mphamvu yamagetsi ya benchtop, momwe tingaigwiritsire ntchito bwino, komanso zomwe muyenera kuyang'ana posankha mtundu.

Kodi Benchtop Power Supply ndi chiyani?

Mukagwira ntchito pa projekiti yomwe imafuna mphamvu yeniyeni ya DC, mphamvu yamagetsi ya benchtop ingakhale yothandiza. Kwenikweni mphamvu yamagetsi yaying'ono yomwe idapangidwira kukhala pabenchi yanu yogwirira ntchito.

Zipangizozi zimadziwikanso kuti magetsi opezeka m'ma labu, magetsi opezeka m'ma DC, ndi magetsi okonzedwa. Ndi abwino kwambiri pa zamagetsi kwa iwo omwe akufuna kupeza magetsi odalirika komanso osavuta kugwiritsa ntchito.

Ngakhale pali mitundu ingapo yamagetsi omwe alipo - kuphatikizapo omwe ali ndi ntchito zolumikizirana, mitundu yosiyanasiyana yotulutsa, ndi ena okhala ndi mawonekedwe osiyanasiyana - onse adapangidwa kuti ntchito zanu zikhale zosavuta komanso zolondola.

Kodi imagwira ntchito bwanji?

Mphamvu yamagetsi ya benchtop ndi chipangizo chogwiritsidwa ntchito m'njira zosiyanasiyana chomwe chimapereka mphamvu yolamulidwa ku zipangizo zamagetsi. Chimagwira ntchito pokoka chingwe chamagetsi cha AC kuchokera ku mains ndikuchisefa kuti chipereke mphamvu ya DC yokhazikika. Njirayi imaphatikizapo zigawo zingapo, kuphatikizapo transformer, rectifier, capacitor, ndi voltage regulator.

Mwachitsanzo, mu mphamvu yamagetsi yolunjika, transformer imatsitsa mphamvu yamagetsi kufika pamlingo wosavuta kugwiritsa ntchito, chosinthira magetsi chimasintha mphamvu yamagetsi ya AC kukhala DC, capacitor imasefa phokoso lililonse lotsala, ndipo chowongolera mphamvu yamagetsi chimatsimikizira kutulutsa kwamphamvu kwa DC. Pokhala ndi mphamvu yosintha mphamvu yamagetsi ndi mphamvu yamagetsi ndikuteteza zida ku mphamvu yochulukirapo, mphamvu yamagetsi ya benchtop ndi chida chofunikira kwambiri pamakina owunikira okha, thandizo lophunzitsira kusukulu, ndi zina zotero.

N’chifukwa chiyani n’kofunika?

Mphamvu yamagetsi ya benchtop singakhale chipangizo chokongola kwambiri mu labu ya mainjiniya amagetsi, koma kufunika kwake sikunganyalanyazidwe. Popanda imodzi, kuyesa ndi kupanga zitsanzo sikungatheke poyamba.

Magesi a Benchtop amapereka magwero odalirika komanso okhazikika a magetsi oyesera ndi kuyika magetsi m'mabwalo amagetsi. Amalola mainjiniya kusintha magetsi ndi mphamvu yamagetsi ku zigawo kuti ayesere malire awo, kuwona momwe amagwirira ntchito m'magwiritsidwe osiyanasiyana, ndikuwonetsetsa kuti agwira ntchito bwino mu chinthu chomaliza.

Kugula magetsi abwino kwambiri sikungawoneke ngati chinthu chodula kwambiri. Komabe, kungathandize kwambiri pakupanga ndi kupanga magetsi pogwiritsa ntchito zipangizo zamagetsi.
