Basic composition of switching power supply
1. Dunhu guru
Impulse ikozvino muganho: dzikamisa iyo impulse ikozvino padivi rekuisa kana simba rakabatidzwa.
Input sefa: Basa rayo ndere kusefa iyo clutter iripo mugidhi remagetsi uye kudzivirira iyo clutter inogadzirwa nemushini kubva mukudzoserwa kumagetsi grid.
Kugadziridza uye kusefa: Gadzirisa zvakananga iyo AC simba regridi kuita rakapfava DC simba.
Inverter: Shandura nzvimbo yakagadziridzwa yemugwagwa kuita yakakwirira-frequency alternating ikozvino, inova chikamu chepakati chepamusoro-frequency switching power supply.
Kugadziriswa kwekubuda uye kusefa: Zvinoenderana nezvinodiwa nemutoro, ipa yakagadzikana uye yakavimbika DC magetsi emagetsi.
2. Kudzora dunhu
Kune rimwe divi, masampula anotorwa kubva kune inobuda terminal uye akaenzaniswa nehuwandu hweseti, uye ipapo inverter inodzorwa kushandura pulse upamhi kana pulse frequency kudzikamisa zvinobuda.Kune rimwe divi, zvinoenderana nedata rakapihwa nedunhu rekuyedza, dunhu redziviriro rinopa Iyo control circuit inotakura matanho ekudzivirira ega ega ekupa magetsi.

Ipa iyo data yeakasiyana ma parameter uye akasiyana zviridzwa ari kushanda munharaunda yekudzivirira.
4. Simba rebetsero
