Isolated uye isina-yakasarudzika LED mhinduro imwe neimwe ine yayo hunhu uye mamiriro ekushandisa mu LED mwenje tekinoroji.Heino ongororo yakadzama yezvose zviri zviviri sarudzo:
1. Isolated LED mhinduro
A. Tsanangudzo uye maitiro
Kuparadzaniswa nemagetsi:Chinhu chikuru cheiyo yakasarudzika LED mhinduro ndeye magetsi ega pakati peinopinza uye inobuda inopera. Kuzviparadzanisa uku kunogona kuwanikwa kuburikidza neshanduko kana zvimwe zvikamu zvekuzviparadzanisa nevamwe, nekudaro zvichideredza zvakanyanya kukanganiswa kweruzha rwemagetsi kunokonzerwa nekusangana kwakananga uye kukuvadzwa kwezvikamu zvedunhu kunokonzerwa nezvinhu zvakashata senge mheni inorova panguva yekufambiswa kwechiratidzo, kuvandudza kuchengetedzwa uye kuvimbika kwemidziyo.
Safety:Nekuda kwekuvapo kwekuparadzaniswa kwemagetsi, iyo yakasarudzika LED mhinduro ine zvakakosha zvakanakira mukuchengetedza, izvo zvinogona kunyatso kudzivirira njodzi yekuvhunduka kwemagetsi uye kuchengetedza kuchengetedzwa kwevashandisi nemidziyo.
B. Common wedunhu topology
Zvakajairwa zvakasarudzika LED wedunhu topologies zvinosanganisira flyback magetsi emagetsi, insulated switching magetsi, yakasarudzika switching magetsi, yechipiri side resonant converters, kumberi-kuguma vanogamuchira, hybrid magetsi controller, nezvimwe.
Imwe neimwe yeiyi topology ine hunhu hwayo, asi chavanofanana ndechekuti vese vanowana magetsi ega ega pakati pekupinza uye kubuda.
C. Mamiriro ekushandisa
Isolated LED mhinduro dzinowanzo shandiswa mumamiriro ezvinhu ane yakakwira chengetedzo zvinodiwa, senge yakakwira-voltage magetsi emagetsi zvigadzirwa zve LED uye maindasitiri maapplication anoda kwakasimba kuparadzaniswa kwemagetsi.
D. Mamiriro ekushandisa
2. Isiri-yega LED mhinduro
A. Tsanangudzo uye maitiro
Hapana kuparadzaniswa kwemagetsi:Asina-akasarudzika ma LED mhinduro haana magetsi ega ega pakati pekuisa uye kubuda. Iyi mhinduro inowanzo ine yakareruka yedunhu chimiro uye yakakwirira shanduko inoshanda, asi kana ikashandiswa, zvinodikanwa kuve nechokwadi kuti pane imwe nzvimbo yekuzviparadzanisa pakati peiyo yekupedzisira yekupinza uye yekupedzisira inobuda kana kutora mamwe matanho ekuchengetedza kuti ave nechokwadi chekuchengetedzwa kwemidziyo uye. vashandi.
Mutengo uye kushanda zvakanaka:Nekuda kweiyo yakapusa yedunhu chimiro, iyo isiri-yakasarudzika LED mhinduro ine zvimwe zvakanakira mumutengo. Panguva imwecheteyo, kushandiswa kwayo kwekushandura kunowanzove kwakakwirira, iyo inobatsira pakuchengetedza simba uye kuderedza mari.
B. Common wedunhu topology
Common vasiri voga LED redunhu topologies anosanganisira yakananga dhiraivha, akatevedzana magetsi, voltage divider magetsi, etc. Izvi topology zviri nyore uye akakodzera mafomu ane yakakwirira mutengo uye nzvimbo zvinodiwa.
C. Mamiriro ekushandisa
Mishonga ye LED isina-yakasarudzika inowanzo shandiswa mumamiriro ezvinhu ane chengetedzo yakaderera zvinodiwa uye zvakaomesesa zvinodiwa pamutengo nenzvimbo, semarambi madiki akadai se LED fluorescent chubhu.

Muchidimbu, zvigadziriso zve LED zvakasarudzika uye zvisiri zvega zvega zvine zvazvakanakira uye zvazvakaipira, uye zvinofanirwa kusarudzwa zvinoenderana nezvinodiwa chaizvo uye mamiriro mune inoshanda maapplication. Nekufambira mberi kwehunyanzvi uye kudzikiswa kwemitengo, mhinduro mbiri idzi dzinotarisirwa kushandiswa uye kuvandudzwa mune mamwe minda mune ramangwana.
Isu tiri vagadziri vane hunyanzvi mukugadzira yakakwirira uye yakaderera frequency transformers, inductors, magineti cores, uye LED mutyairi magetsi ekushandisa.
