Sezvo tekinoroji ichifambira mberi, kudiwa kwemidziyo yemagetsi kuri kuramba kuchikura. Mukusangana nezvido izvi, high frequency switching DC magetsi mave tekinoroji yakakosha. Kubva pamichina yekufambisa mashoko kuenda kumidziyo yekurapa, kubva pakutonga kwemaindasitiri kuenda kumagetsi emunhu,high frequency switching DC magetsi ekushandisazvakapinda mumativi ese ehupenyu hwedu. Saka, chii chaizvo chinonzi high frequency switching DC magetsi, uye inoshanda sei?
Chekutanga, ngatinzwisise misimboti yayo yakakosha. A high frequency switching DC power supply isimba remagetsi rinogona kushandura epput alternating current (AC) simba kuita yakagadzikana yakananga ikozvino (DC) voltage kubuda. Kuenzaniswa neyechinyakare linear regulators,high-frequency switching DC magetsi ekushandisainopa hunyanzvi hwepamusoro uye saizi diki, ichiita kuti ishandiswe zvakanyanya mumhando dzakasiyana dzemagetsi.
Kushanda kwehigh-frequency switching DC magetsi ekushandisainonyanya kuenderana nezvikamu zviviri zvakakosha: switching regulator uye control circuit. Iyo switching regulator inodzora kubuda kwemagetsi emagetsi uchishandisa yakakwira-frequency switching zvishandiso (senge MOSFETs), nepo control circuit inotarisisa kubuda kwevoltage uye inogadzirisa switching regulator kuchengetedza yakagadzikana inobuda voltage.
Mukuita uku, iyo yekuisa AC simba rinotanga kugadziriswa kuita DC simba kuburikidza neinogadzirisa, yozodzorwa neinochinja regulator, uye inodzikamiswa kuburikidza nedunhu rekutonga. Izvi zvinobudirira simba rekushandura nzira inogonesahigh-frequency switching DC magetsi ekushandisakuti usangopa chete simba rakagadzikana kubuda asiwo kuwana yakakwirira-inoshanda simba shanduko pasi pemamiriro akasiyana emutoro.
Zvikumbiro zvehigh-frequency switching DC magetsi ekushandisazvakasiyana zvakanyanya. Mumunda wemidziyo yekufonera, vanogona kupa yakagadzikana uye yakavimbika simba kuti ive nechokwadi chekushanda kwakajairika kwemidziyo yekutaurirana. Mumidziyo yemakomputa, vanogona kupa yakatsiga simba rutsigiro kune zvikamu zvakaita seCPU uye makadhi emifananidzo. Mundima yemidziyo yekurapa, vanogona kupa chaiyo simba rekubuda kwemidziyo yekurapa kuve nechokwadi chekushanda kwekurapa.
Muchidimbu,high-frequency switching DC magetsi ekushandisatekinoroji dzinoshanda, dzakatsiga, uye dzakavimbika dzekushandura simba izvo zvave chikamu chakakosha chemidziyo yemagetsi yemazuva ano. Nekuenderera mberi kwehunyanzvi hwekuvandudza tekinoroji, zvinotendwa kuti high-frequency switching DC magetsi ekushandisa achaita basa rakatonyanya kukosha mune ramangwana, zvichiunza kurerukirwa uye mikana kuhupenyu hwedu.
