Kuchinja Simba RemagetsiTsananguro: Zvakanakira uye Mashandisirwo
Kuchinja magetsi, inozivikanwawo se switch modemagetsi (SMPS), dzakakurumbira mumaindasitiri akasiyana-siyana nekuda kwekushanda zvakanaka uye kuchinjika kwadzo. Nekuda kwekugona kwadzo kushandura simba zvinobudirira kubva kune imwe nzira kuenda kune imwe,magetsi ekuchinjazvave mhinduro inosarudzwa yemhando dzakasiyana dzemashandisirwo kubva kumagetsi evatengi kusvika kumidziyo yeindasitiri.
Mumagetsi ekare anoshandiswa nemagetsi akatsetseka, simba rinodzorwa nekubvisa simba rakawandisa muchimiro chekupisa, zvichikonzera kushanda kwakaderera. Zvisinei,magetsi ekuchinjavakachinja indasitiri iyi nekubatanidza ma transistors emagetsi anogona kushandurwa zvinobudirira pakati pemamiriro ekushanda nekushanda, zvichideredza kurasikirwa kwesimba. Kushanda kwekuchinja uku kunowedzera kushanda zvakanaka uye kunoderedza kugadzirwa kwekupisa, zvichiita kuti ive yakakodzera kushandiswa kwakawanda.
Chimwe chezvakanakira zvikuru zvemagetsi ekuchinjasaizi yadzo diki. Kuderedzwa kwekurasikirwa kwesimba kunobvumira kushandiswa kwezvikamu zvidiki, zvichiita kuti zvive zvakanaka kune zvishandiso zvine nzvimbo shoma senge nharembozha. Pamusoro pezvo, zvichienzaniswa nemagetsi akatsetseka, magetsi anochinja-chinja ane huremu hwakareruka, zvichiwedzera kutakurika kwawo uye nyore kushandisa.
Kuchinja magetsizvakare inopa huwandu hwakakura hwemagetsi ekupinda, zvichiita kuti zvienderane nemagetsi akasiyana-siyana munzvimbo dzakasiyana. Kuchinja-chinja uku kunoita kuti zvishandiso zvemagetsi zvigone kushanda pasi rese pasina kudiwa kwemamwe maadapta kana shanduko. Pamusoro pezvo, magetsi anochinja anogonawo kubata mavoltage akasiyana-siyana ekubuda, zvichivabvumira kupa simba kumidziyo yakasiyana-siyana ine zvinodiwa zvakasiyana zvemagetsi.
Panyaya yekuvimbika,magetsi ekuchinjaane mabhenefiti pane magetsi anowanikwa mumagetsi. Dhizaini yavo yakasimba inobvisa kudiwa kwezvinhu zvakakura uye zvinokanganisa kushanda zvakaita sematransformer nema capacitor. Izvi zvinowedzera hupenyu hwebasa uye zvinovandudza kuvimbika kwehurongwa hwemagetsi.
Kuchinjika kwemagetsi ekuchinjaZvinosvika pamhando dzakasiyana-siyana dzemashandisirwo azvo. Kubva pakushandisa magetsi emagetsi evatengi akadai semafoni, malaptop, uye maconsoles emitambo, kusvika kumashandisirwo akawanda emaindasitiri akadai sekutaurirana, ndege, uye michina yekurapa, hazvina anoenzana pakuchinjika kwazvo. Pamusoro pezvo, magetsi anochinjika anowanzo shandiswa mumasisitimu esimba rinogona kushandiswazve senge solar panels nema wind turbines nekuda kwesimba rawo rekushandura simba uye kutonga.
Kunyangwe zvakadaromagetsi ekuchinjaZvine zvakanakira zvakawanda, zvinewo zvimwe zvisingakwanisike. Semuenzaniso, zvinogona kuunza electromagnetic interference (EMI) nekuda kwekushanda kwe high-frequency switching operations. Kuti dambudziko iri ripere, zvimwe zvikamu zve filter zvinowanzo shandiswa. Pamusoro pezvo, kugadzira nekugadzira magetsi e switching kunoda ruzivo rwakakosha nehunyanzvi kuti zvive nechokwadi chekuti mashandiro akakodzera uye kuchengetedzeka.
Mukupedzisa,magetsi ekuchinjavakachinja indasitiri yemagetsi nekushanda kwavo kwakanyanya, saizi yavo diki, uye kushanduka-shanduka. Kugona kushandura simba zvinobudirira uye kukwirira kwemagetsi ekupinda nekubuda kunoita kuti ive sarudzo yekutanga kune akawanda mashandisirwo. Sezvo tekinoroji ichiramba ichifambira mberi,magetsi ekuchinjapasina mubvunzo zvichaita basa guru mukupa simba kumidziyo nemasisitimu emangwana.
