12v switching power supply ndeye kushandisa magetsi ekuchinja zvinhu (senge transistors, field effect transistors, thyristors, etc.) kugadzira magetsi emagetsi "on" uye "off" nguva dzose kuburikidza nedunhu rekutonga, kuitira kuti magetsi ekushandura Pulse. modulation inoitwa pane yekuisa voltage kuti uone DC/AC, DC/DC voltage shanduko, pamwe neinogadziriswa inobuda voltage uye otomatiki voltage regulation.

.Iyo yekare yekushanda mode inonyanya kushandiswa kune DC / AC inverter magetsi, kana DC / DC voltage kutendeuka;maviri ekupedzisira ekushanda modes anonyanya kushandiswa kuchinjika yakadzorwa magetsi ekupa.Uye zvakare, iyo inobuda voltage yeiyo switching magetsi inewo matatu ekushanda modes: yakananga kubuda voltage modhi, avhareji yekubuda voltage modhi, uye amplitude kubuda voltage mode.Saizvozvo, iyo yekare yekushanda mode inonyanya kushandiswa kune DC / AC inverter magetsi, kana DC / DC voltage kutendeuka;maviri ekupedzisira ekushanda modes anonyanya kushandiswa kuchinjika yakadzorwa magetsi ekupa.

Zvinoenderana nemabatirwo emagetsi ekuchinja akabatanidzwa mudunhu, iyo yakawanda inoshandiswa switching magetsi inogona kukamurwa kuita zvikamu zvitatu: akateedzana switching magetsi emagetsi, parallel switching magetsi, uye transformer switching magetsi.Pakati pavo, transformer switching power supply (inozonzi inonzi transformer switching power supply) inogona kukamurwazve kuva: push-pull type, half-bridge type, full-bridge type, etc.;maererano nekunakidzwa kwe transformer uye chikamu chekubuda kwemagetsi, inogona kuparadzaniswa zvakare kuva: mberi excitation type, flyback, single-excitation uye mbiri-excitation, nezvimwewo;kana yakakamurwa kushandiswa, inogona kukamurwa kuva mamwe marudzi.

Pazasi isu tichasuma muchidimbu misimboti yekushanda yeatatu ekutanga ekuchinja magetsi emagetsi, senge akateedzana, parallel, uye transformer.Mamwe marudzi ekuchinja magetsi anozoongororwawo zvakadzama nhanho nhanho.
