Txawm hais tias Schottky diodes tau nyob hauv kev ua lag luam rau ntau xyoo lawm, kev tsim kho tshiab thiab cov khoom lag luam tau txuas ntxiv txhim kho nws cov yam ntxwv thiab nthuav dav qhov ua tau zoo ntawm daim ntawv thov. Ntxiv nrog rau lub hnub ci vaj huam sib luag thiab tsheb, tam sim no lawv kuj tau siv los ua roj teeb chargers rau laptops, smartphones thiab ntsiav tshuaj. Tab sis qhov twg Schottky diodes haum rau lub hom phiaj twg?
Schottky diodes yog siv nyob rau hauv ob qho tib si nram qab no:
1. Rectification, nyob rau hauv lwm yam lus, AC rau DC hloov dua siab tshiab thiab DC voltage conversion nyob rau hauv ib tug switching fais fab mov (SMPS) los yog lub hwj chim rectifier.
2. Tiv thaiv qhov thim rov qab ntawm DC tam sim no thiab DC ntawm qhov sib txawv polarity, piv txwv li, thaum lub roj teeb tso rau qhov tsis raug.
Vim nws qhov kev hloov pauv siab ceev, Schottky diodes feem ntau yog siv rau kev siv ntau zaus mus txog rau lub microwave ntau. Qhov no kuj yog vim lawv tsis muaj peev xwm saturation. Yog li ntawd, lawv feem ntau yog siv los ua kev tiv thaiv diodes rau txo qhov induced voltage nyob rau hauv daim ntawv ntawm freewheeling diodes los yog rectifier diodes nyob rau hauv switching fais fab mov, thiab kuj yuav siv tau raws li demodulators rau nrhiav kom tau circuits.
Vim li cas qee cov diodes muaj peb txoj kev qhuab qhia?
Qee qhov diode sab nrauv duab triodes siv rau tag nrho yoj rectification yog ntim nrog ob lub diodes txuas nrog rov qab (qhov tsis zoo electrodes txuas ua ke). Feem ntau, qhov nruab nrab yog qhov tsis zoo electrode, thiaj li txuag tau qhov chaw thiab ua rau lub rooj tsav xwm hauv Circuit Court ntau compact.
