Ndi madera ati?

Ndi madera ati omwe akusinthira magetsi ndi ma linear magetsi oyenera
Kusintha magetsi sikufuna thiransifoma kuti itembenuzire mphamvu ya mzere wa AC molunjika ku voliyumu ya DC, ndiyeno sinthani voliyumu ya DC yaiwisiyo kukhala siginecha ya AC yothamanga kwambiri yomwe idzagwiritsidwe ntchito pamayendedwe owongolera kuti apange magetsi ofunikira komanso apano.
Mapangidwe amagetsi opangira magetsi amagwiritsa ntchito voteji ya AC ku chosinthira mphamvu kuti ikweze kapena kutsitsa voteji isanagwiritsidwe ntchito pagawo lowongolera.Popeza kukula kwa thiransifoma kumayenderana mosagwirizana ndi ma frequency ogwiritsira ntchito, izi zitha kubweretsa mphamvu yayikulu komanso yolemetsa.
Mtundu uliwonse wa ntchito yopangira magetsi uli ndi ubwino ndi zovuta zake.Mphamvu yosinthira ndi 80 peresenti yaying'ono komanso yopepuka kuposa mphamvu yofananira, koma imatulutsa phokoso lambiri lomwe lingasokoneze zida zamagetsi.Mosiyana ndi magetsi oyendera mizere, magetsi osinthira amatha kupirira kutayika kwa AC mumitundu ya 10-20 ms osakhudza zotulutsa.
Mphamvu zamagetsi zama linear zimafunikira zida zazikulu za semiconductor kuti ziwongolere voteji zomwe zimatulutsa motero zimatulutsa kutentha kwambiri, komwe kumachepetsa mphamvu zamagetsi.Pakutulutsa kwa 24V, magetsi am'mizere nthawi zambiri amakhala pafupifupi 60 peresenti, poyerekeza ndi 80 peresenti kapena kupitilira apo pamagetsi osinthira.Mphamvu zamagetsi zama linear zimakhala ndi nthawi yoyankha mwachangu kuposa ma switch-mode anzawo, zomwe ndizofunikira m'malo ena.Nthawi zambiri, magetsi osinthika amakhala opepuka komanso ophatikizika, kuwapangitsa kukhala oyenera pazida zonyamulika.Mphamvu zamagetsi zama linear ndizoyenera kupatsa mphamvu ma analogi chifukwa cha phokoso lawo lochepa lamagetsi komanso kuwongolera kosavuta.

Zolakwa zofala

Zolakwika zofala pakusintha magetsi.
Kodi cholakwika chofala pakusintha magetsi ndi chiyani?Cholakwika chofala pakusintha magetsi ndikusintha kwa transistor komwe.Transistor yaifupi imapangitsa kuti madzi ambiri aziyenda mu thiransifoma ndikuwomba fusesi.
Kulephera kwa transistor nthawi zambiri kumachitika chifukwa cha ma capacitor oyipa.Pezani capacitor yotupa kapena yotsika yotulutsa ndikuyika ma capacitor omwe akuwoneka oyipa.Kuti muyimitse kulephera kofalaku kuti zisachitikenso, chotulutsa cha fyuluta chiyenera kusinthidwa ndi capacitor.Ambiri opanga magetsi samayika ma capacitor otsika a ESR ngati zida zoyambirira chifukwa ndi okwera mtengo kuposa ma capacitor wamba.Komabe, ndikofunikira kuzigwiritsa ntchito ngati zida zosinthira chifukwa zimathandizira kwambiri moyo wamagetsi.
Kulephera kwa diode ndi vuto lina lofala.Pali ma diode ambiri pamagetsi osinthira ndipo kulephera kwa diode kumapangitsa kuti magetsi aziwombera fuse kapena kuzimitsa.Kulephera kofala kwa diode ndikozungulira kwakanthawi mu +12 volt kapena -5 volt output rectifier.Zina mwazolephera izi zitha kuchitika chifukwa chogwiritsa ntchito zotulutsa +12 kapena -5 volt.The high voltage input diode ingathenso kufupikitsidwa.
