Paunenge uchishongedza nekugadzira tambo, iwe zvakare unofanirwa kuterera kune kusarudzwa kweiyo huru simba switch.Mushure mezvose, kune akawanda makuru emagetsi switch, uye anofananidzwa neakasiyana voltage renji uye simba rekubuda.mutoro maitiro, etc. Izvi zvinotevera nzira yekusarudza nzira yekushanda yekushandura magetsi uye kushandura magetsi.Mukati mekusarudza shanduko yemagetsi, tinogona kutarisisa kumatambudziko iwayo, uye tozoedza kusarudza yakaziviswa yekuchinja magetsi emagetsi zvigadzirwa, uye mhedzisiro yekushandisa ichave iri nani.
Nzira yekusarudza switching power supply.
Pakusarudza yekuchinja magetsi, iyo yekuisa voltage renji, ine mwero kubuda simba, hunhu hwekuremerwa, uye tembiricha yekushandisa inofanirwa kutariswa.
1. Sarudza iyo yakakodzera yekuisa voltage renji.Tora kutaurirana kutaipa semuenzaniso.Common input voltage specifications i110V uye 220V, saka kune 110V.220V AC conversion uye general input voltage (AC: 85V-2 ** V).Iyo yekuisa voltage specition modhi inofanirwa kusarudzwa zvinoenderana nenzvimbo yekushandisa.
2. Sarudza simba rekubuda rakakodzera.Simba rekushandura rinoshandisa chikamu chemagetsi ekubuda panguva yekushanda uye inoibudisa sesimba rekupisa.Kuti uwedzere zvirinani hupenyu hwesevhisi yekuchinja kwemagetsi, zvinokurudzirwa kusarudza michina ine yakayerwa simba rinopfuura 30%.
3. Funga nezvekutakura maitiro.Kuti uvandudze kugadzikana kweiyo inoshanda sisitimu, zvinokurudzirwa kushandura magetsi ari kushanda pasi pemutoro we50% -80%, kureva, tichifunga kuti iyo inowanzo kubuda simba ndeye 20W, inoshandura magetsi ine simba re25W-40W rinofanira kusarudzwa.
Kana mutoro wacho uri mota, girobhu remwenje kana capacitor mutoro, ikozvino yakakura zvakanyanya painotangira, uye yakakodzera switching magetsi inofanira kusarudzwa kudzivirira mutoro.Kana mutoro uri mota, kudzoserwa kwemagetsi pakuvhara kunofanirwa kutariswa.
4. Mukuwedzera, tembiricha yekushanda yemagetsi ekuchinja uye kana pane yakawandisa yekubatsira kutonhora michina inofanirawo kutariswa.Iyo tembiricha inonzwa switching magetsi ane yakawandisa anofanirwa kuderedza kubuda.Ndokumbira utarise kune yekudzikisa curve yetembiricha inonzwa simba.
Ndeipi nzira yekushanda yekuchinja kwemagetsi?
Frequency.Pulse width fixed mode, frequency yakagadziriswa.Pulse width variable mode, frequency.Pulse width variable mode.
1. Iyo yekare yekushanda mode inonyanya kushandiswa mu DC / AC variable frequency power supply kana DC / DC voltage conversion;maviri ekupedzisira anoshanda modes anonyanya kushandiswa mukuchinja inodzorwa magetsi ekupa.
2. Pamusoro pezvo, magetsi emagetsi ekuchinja magetsi anewo maitiro matatu ekushanda: nzira yekukurumidza kubuda magetsi, avhareji yekubuda kwemagetsi nzira, uye amplitude value output voltage method.
3. Nenzira imwecheteyo, iyo yekare yekushanda nzira inonyanya kushandiswa mu DC / AC variable frequency power supply kana DC / DC voltage conversion;nzira mbiri dzekupedzisira dzekushanda dzinonyanya kushandiswa pakuchinja inogadziriswa magetsi.
Zvinoenderana neiyo interface mode ye switch kabati mune yekudzora wedunhu, iyo yekuchinjisa magetsi inogona kukamurwa kuita marudzi matatu: akatevedzana ekuchinja magetsi, parallel switching magetsi ekupa, uye transformer switching magetsi.Pakati pavo, iyo transformer inoshandura simba rekupa (inozonzi iyo transformer switching power supply) inogona zvakare kukamurwa kuva: sliding gonhi rudzi, semi-flat ruoko, yakazara bhiriji mhando, nezvimwewo;maererano nekukurudzira kwesimba rekushandura uye mutsauko wechikamu chekubuda kwemhepo, inogona kugoverwa kuva: mberi kufadza, reverse Inofara, imwe-inofadza, kaviri-inofara;kana chinangwa chikuru chakakamurwa kuva nhamba huru yemhando.
Izvo zviri pamusoro apa maitiro ekusarudza maitiro ekushanda ekuchinja magetsi uye kushandura magetsi.Paunosarudza iyo huru yemagetsi switch, iwe unofanirwa kuona zvakajeka iyo voltage standard uye inonzwisisika yekubuda simba.Kana iyo voltage iri yakakwira, iwe unofanirwawo kudzora huwandu hwezvinhu izvi.Mukuwedzera, chaizvoizvo, kushandura kwemagetsi kune maitiro akasiyana-siyana ekushanda, kusanganisira yakagadziriswa frequency, pulse width, nezvimwewo, saka inofanira kusarudzwa maererano nehuwandu hwekushanda mumba.
