Sezvo tekinoroji ichifambira mberi, kudiwa kwemidziyo yemagetsi kuri kuramba kuchikura. Mukuzadzisa zvinodiwa izvi, magetsi eDC anochinjika kakawanda ave tekinoroji yakakosha. Kubva pamidziyo yekutaurirana kusvika kumidziyo yekurapa, kubva pamidziyo yeindasitiri kusvika kumidziyo yemagetsi yemunhu,magetsi eDC anochinja-chinja kakawandazvakapinda muhupenyu hwedu hwese. Saka, chii chinonzi high frequency switching DC power supply, uye inoshanda sei?
Chekutanga, ngatinzwisisei misimboti yayo yekutanga. Simba reDC rinochinja-chinja frequency high isimba rinogona kushandura simba remagetsi rinopinda (AC) kuita simba remagetsi rinobuda (stable direct current) (DC). Zvichienzaniswa nemagetsi emagetsi ekare,magetsi eDC anochinja-chinja kakawandainopa kushanda kwepamusoro uye saizi diki, zvichiita kuti ishandiswe zvakanyanya mumidziyo yakasiyana-siyana yemagetsi.
Kushanda kwemagetsi eDC anochinja-chinja kakawandainonyanya kuenderana nezvinhu zviviri zvakakosha: chinogadzirisa magetsi (switching regulator) nedunhu rekudzora. Chinodzora magetsi (switching regulator) chinodzora magetsi anobuda (output voltage) emagetsi achishandisa michina yekuchinja magetsi ine mafrequency akawanda (senge MOSFETs), ukuwo chinogadzirisa magetsi anobuda (control circuit) chichiongorora magetsi anobuda (output voltage) uye chinogadzirisa chinogadzirisa magetsi anobuda (switching regulator) kuti chirambe chakasimba.
Mukuita uku, simba reAC rinopinda rinotanga ragadziriswa kuita simba reDC kuburikidza ne rectifier, rozodzorwa ne switching regulator, uye rogadzikiswa kuburikidza ne control circuit. Maitiro aya ekushandura simba anoshanda anogonesamagetsi eDC anochinja-chinja kakawandakwete kungopa simba rakagadzikana rinobuda chete asiwo kuwana simba rinoshanduka zvakanyanya pasi pemamiriro akasiyana emutoro.
Mashandisirwo emagetsi eDC anochinja-chinja kakawandadzakasiyana-siyana zvikuru. Mumichina yekutaurirana, vanogona kupa simba rakasimba uye rakavimbika kuti vave nechokwadi chekuti michina yekutaurirana inoshanda zvakanaka. Mumichina yemakombiyuta, vanogona kupa rutsigiro rwesimba rakasimba kuzvinhu zvakaita semaCPU nemakadhi emifananidzo. Mumichina yekurapa, vanogona kupa simba rakakodzera rekushandisa michina yekurapa kuti vave nechokwadi chekuti kurapwa kwacho kunoshanda zvakanaka.
Muchidimbu,magetsi eDC anochinja-chinja kakawandamatekinoroji ekushandura simba anoshanda zvakanaka, akagadzikana, uye akavimbika ayo ave chikamu chakakosha chemidziyo yemagetsi yemazuva ano. Nekuvandudzwa kwetekinoroji kuri kuenderera mberi, zvinotendwa kuti magetsi eDC anochinja-chinja kakawanda achaita basa rakakosha mune ramangwana, zvichiunza nyore uye mikana muhupenyu hwedu.
