Nekuzivikanwa kwemidziyo yemagetsi, kushandura magetsi kunoshandiswa zvakanyanya muhupenyu hwedu hwezuva nezuva, uye inzira yakakosha yekugovera magetsi.Ipapo mupepeti anozounza switching magetsi uye mashandisirwo ayo minda kwauri.
Nekukurumidza kukura kwesimba remagetsi tekinoroji, hukama pakati pemagetsi emagetsi emagetsi nebasa revanhu uye hupenyu hwave huchiwedzera kuswedera, uye zvigadzirwa zvemagetsi hazviparadzaniswe kubva kune akavimbika magetsi emagetsi.Mumakore ekuma1980, magetsi emakombuta akanyatsoona kushandura magetsi, uye akatungamira mukupedzisa kugadzirwa kwemakomputa.Kuchinja magetsi kwakapinda munzvimbo dzakasiyana dzemagetsi nemagetsi muma1990s.Kuchinja kwemagetsi emagetsi kwave kushandiswa zvakanyanya muchirongwa-chinodzorwa switch, kutaurirana, magetsi ekuyedza emagetsi magetsi, uye kudzora emagetsi emagetsi emagetsi, izvo zvakasimudzira kukurumidza kusimudzira kwekuchinja magetsi emagetsi..Kuchinja kwemagetsi magetsi anoshandisa tekinoroji yemagetsi emazuva ano kudzora chiyero chenguva yekuchinja ma transistors nekudzima kuti ichengetedze yakagadzikana inobuda voltage.Kuchinja magetsi kunowanzo kuumbwa nepulse width modulation (PWM) control ICs uye MOSFETs.Kuenzaniswa nemagetsi emagetsi emagetsi, mutengo wemagetsi ekuchinja unowedzera nekuwedzera kwesimba rekubuda, asi chiyero chekukura kwezviviri zvakasiyana.Mutengo wemagetsi emutsetse wakakwirisa kupfuura wekuchinja magetsi pane imwe nzvimbo inobuda magetsi, inova mutengo wekudzoka.Nekuvandudzwa uye hunyanzvi hwemagetsi emagetsi tekinoroji, kushandura tekinoroji yemagetsi inogara ichivandudza, uye iyi mutengo wekudzosera nzvimbo iri kuramba ichienda kune yakaderera kubuda kwemagetsi kupera, iyo inopa yakakura nzvimbo yekusimudzira yekuchinja magetsi.
Simba rekushandura magetsi nderokushandisa magetsi ekushandura magetsi akadai se transistors, field effect transistors, thyristors, nezvimwewo, kuburikidza nedunhu rekutonga, kuita kuti magetsi emagetsi "ave" uye "akadzimwa" nguva dzose, kuitira kuti magetsi ekugadzirisa magetsi agone. pindura kumagetsi ekupinza.Ita pulse modulation kuti uone DC / AC uye DC / DC voltage shanduko, pamwe neinogadziriswa inobuda voltage uye otomatiki voltage kudzikamisa.Kuchinja magetsi kunowanzo kuumbwa nepulse width modulation (PWM) control ICs uye MOSFETs.Nekuvandudzwa uye kuvandudzwa kwemagetsi emagetsi tekinoroji, magetsi ekuchinja aripo anoshandiswa zvakanyanya munenge zvese zvemagetsi midziyo kunyanya nekuda kwehukuru hwayo, huremu hwayo uye kugona kwakanyanya, uye kukosha kwayo kunoonekwa.
High-frequency switching power supply ndiyo nzira yekukura kwayo.High-frequency inoita kuti shanduko yemagetsi iite miniaturized uye inogonesa kushandura magetsi kuti apinde muhuwandu hwakawanda hwemashandisirwo, kunyanya mumunda wepamusoro-tekinoroji, inosimudzira miniaturization uye kureruka kwezvigadzirwa zvepamusoro-soro.shanduko.Pamusoro pezvo, kuvandudza uye kushandiswa kwekuchinja magetsi kune zvakakosha mukuchengetedza simba, kuchengetedza zviwanikwa nekuchengetedza nharaunda.
People's switching power supply tekinoroji iri kugadzira zvine chekuita nemagetsi emagetsi midziyo uku ichigadzira switching frequency conversion tekinoroji.Kukurudzirana kwezviviri izvi kunosimudzira magetsi ekuchinja kuti ave akareruka, madiki, matete, ruzha rwakaderera, kuvimbika kwepamusoro, nekukura kwenhamba dzinopfuura mbiri gore rega rega.Nhungamiro yekusimudzira kurwisa-kupindira.Kuchinja magetsi emagetsi kunogona kukamurwa kuita mapoka maviri: AC/DC uye DC/DC.DC/DC converters yakagadziridzwa, uye tekinoroji yekugadzira uye maitiro ekugadzira akakura uye akamisikidzwa kumba nekune dzimwe nyika, uye akazivikanwa nevashandisi, asi The modularization yeAC/DC, nekuda kwehunhu hwayo, inoita kuti isangane nezvimwe. yakaoma tekinoroji uye maitiro ekugadzira matambudziko mukuita modularization.Chimiro uye maitiro emhando mbiri dzekuchinja magetsi anotsanangurwa pazasi.

Kushandura magetsi emagetsi anoshandiswa zvakanyanya mumaindasitiri otomatiki kutonga, midziyo yemauto, zvesainzi zvekutsvagisa, mwenje we LED, midziyo yekudzora maindasitiri, midziyo yekutaurirana, midziyo yemagetsi, chiridzwa, midziyo yekurapa, semiconductor firiji nekudziya, kuchenesa mhepo, mafiriji emagetsi, zviratidziro zvekristaro yemvura. , mwenje we LED , Zvombo zvekukurukurirana, zvigadzirwa zvinonzwika-zvinotaridzika, kutarisa kwekuchengetedza, mabhegi emwenje e LED, makesi emakomputa, zvigadzirwa zvemadhijitari uye zviridzwa nemimwe minda.
