Kusintha magetsi ndi mtundu wamagetsi omwe amagwiritsa ntchito magetsi amakono kuti azitha kuwongolera nthawi yoyatsa ndi kuzimitsa nthawi kuti asunge voteji yokhazikika.Magetsi osinthira nthawi zambiri amakhala ndi ma pulse wide modulation (PWM) control ICs ndi MOSFET.Ndi chitukuko ndi luso laukadaulo wamagetsi amagetsi, ukadaulo wosinthira magetsi umakhalanso wakupanga zatsopano.Pakalipano, magetsi osinthika amagwiritsidwa ntchito kwambiri pafupifupi pafupifupi zipangizo zonse zamagetsi chifukwa cha kukula kwake kochepa, kulemera kwake komanso kudalirika kwambiri.Ndi njira yofunikira kwambiri yoperekera mphamvu pakutukuka kwachangu kwamakampani amakono apakompyuta.
Kugwiritsa ntchito kwambiri: Kusinthana kwamagetsi kumagwiritsidwa ntchito kwambiri pakuwongolera makina opanga mafakitale, zida zankhondo, zida zofufuzira zasayansi, kuyatsa kwa LED, zida zowongolera mafakitale, zida zolumikizirana, zida zamagetsi, zida zankhondo, zida zamankhwala, firiji ya semiconductor ndi kutentha, oyeretsa mpweya, zamagetsi. firiji, makhiristo amadzimadzi Amawonetsa, nyali za LED, kuyang'anira chitetezo, zinthu zama digito ndi zida ndi magawo ena.
Basic zikuchokera kusintha magetsi
1. Dera lalikulu
Malire apano a Impulse: chepetsani mphamvu yapano pa mbali yolowera mphamvu ikayatsidwa.
Zosefera zolowetsa: Ntchito yake ndikusefa zinthu zomwe zili mu gridi yamagetsi ndikuletsa kusokoneza komwe kumapangidwa ndi makinawo kuti zisabwezedwe ku gridi yamagetsi.
Kukonza ndi kusefa: Konzani mwachindunji mphamvu ya AC ya gululi kukhala mphamvu yosalala ya DC.
Inverter : Sinthani mtunda wokonzedwanso kukhala ma frequency amtundu waposachedwa, womwe ndi gawo loyambira lamagetsi osinthira pafupipafupi.
Kukonza zotulutsa ndi kusefa: Malinga ndi zosowa za katunduyo, perekani magetsi okhazikika komanso odalirika a DC.
2. Kuwongolera dera
Kumbali imodzi, zitsanzo zimatengedwa kuchokera ku terminal yotulutsa ndikufaniziridwa ndi mtengo wokhazikitsidwa, ndiyeno inverter imayendetsedwa kuti isinthe kuchuluka kwa pulse kapena pafupipafupi kuti ikhazikike.Kumbali inayi, malinga ndi zomwe zimaperekedwa ndi dera loyesa, dera lachitetezo limapereka Gawo lowongolera limachita njira zodzitetezera pamagetsi.
3. Kuzindikira dera
Perekani zidziwitso zamagawo osiyanasiyana ndi zida zosiyanasiyana zomwe zikugwira ntchito mudera lachitetezo.
4. Mphamvu zothandizira
Zindikirani mapulogalamu (akutali) akuyamba kwa magetsi, ndikupatseni mphamvu zozungulira chitetezo ndi dera lowongolera (tchipisi monga PWM)
