Popanga ma switching power supply kapena motor drive circuit pogwiritsa ntchito MOSFETs, anthu ambiri amalingalira za on-resistance, maximum voltage, maximum current, etc. za MOSFETs, ndipo anthu ambiri amangoganizira izi zokha. Dera loterolo litha kugwira ntchito, koma silo yankho labwino kwambiri, ndipo izi siziloledwa ngati kapangidwe kazinthu zokhazikika. Ndiye zomwe zingakhale zofunikira pazabwinoMOSFET driver circuit? Tiyeni tifufuze!
(1) Chophimbacho chikayatsa nthawi yomweyo, woyendetsa galimotoyo ayenera kupereka mphamvu yokwanira yolipiritsa, kutiMOSFET voteji yochokera pachipata imakwezedwa mwachangu kumtengo womwe ukufunidwa, ndikuwonetsetsa kuti chosinthiracho chikhoza kuyatsidwa mwachangu ndipo palibe ma oscillation apamwamba kwambiri pamphepete mwakukwera.
(2) Mu kusintha kwa nthawi, dera loyendetsa galimoto liyenera kuwonetsetsa kutiMOSFET chipata gwero voteji amakhalabe okhazikika, ndi conduction odalirika.
(3) Kuzimitsa nthawi yomweyo kuyendetsa galimoto, kuyenera kupereka njira yochepetsera pang'onopang'ono momwe mungathere, ku chipata cha MOSFET gwero la capacitive voltage pakati pa maelekitirodi a kutuluka mofulumira, kuonetsetsa kuti chosinthiracho chikhoza kuzimitsidwa mwamsanga.
(4) Mayendedwe oyendetsa dera ndi osavuta komanso odalirika, otsika otsika.
