Izidingo Eziyisisekelo Zezifunda Zomshayeli We-MOSFET

Izidingo Eziyisisekelo ze-MOSFET Driver Circuits

Isikhathi Sokuthumela: May-21-2024

Lapho uklama ugesi oshintshwayo noma isekethe yedrayivu yezimoto usebenzisa ama-MOSFET, abantu abaningi bacabangela ukumelana ne-on-resistance, i-voltage ephezulu, umthamo wamanje omkhulu, njll. wama-MOSFET, futhi abantu abaningi bacabangela lezi zici kuphela. Isifunda esinjalo singase sisebenze, kodwa akusona isisombululo esifanele, futhi lokhu akuvunyelwe njengomklamo womkhiqizo osemthethweni. Ngakho-ke kungaba yini izidingo zokuhleI-MOSFET isifunda somshayeli? Ake sithole!

(1) Lapho inkinobho ivuleka khona manjalo, isekethe yomshayeli kufanele ikwazi ukuhlinzeka ngamandla anele okushaja, ukuzeI-MOSFET i-voltage yomthombo wesango ikhushulwa ngokushesha enanini elifiswayo, nokuqinisekisa ukuthi iswishi ingavulwa ngokushesha futhi awekho ama-oscillations aphezulu onqenqemeni olukhuphukayo.

(2) Esikhathini sokushintshwa kwenkathi, umjikelezo wedrayivu udinga ukwazi ukuqinisekisa ukuthiI-MOSFET I-voltage yomthombo wesango ihlala izinzile, kanye nokuqhutshwa okuthembekile.

(3) Ukucisha umjikelezo wedrayivu osheshayo, kudingeka ukwazi ukuhlinzeka ngendlela ephansi ye-impedance ngangokunokwenzeka, kugesi we-capacitive wesango le-MOSFET phakathi kwama-electrode okukhipha ngokushesha, ukuze kuqinisekiswe ukuthi iswishi ingacishwa ngokushesha.

(4) Isakhiwo sesifunda seDrayivu silula futhi sithembekile, ukulahlekelwa okuphansi.
