Za chiphunzitso choyambirira cha ma transistors ofananira ndi ma MOSFET: Choyamba, ma transistors amakhala ndi kutentha kwapang'onopang'ono, ndiye kuti, kutentha kwa transistor komwe kumakwera, kukana kudzakhala kochepa. Kachiwiri, ma MOSFET ali ndi kutentha kwabwino kwambiri poyerekeza ndi ma transistors, zomwe zikutanthauza kuti kutentha kumakwera, kukana kumawonjezeka pang'onopang'ono.
Poyerekeza ndi ma transistors, ma MOSFET ndiwoyeneranso kufananitsa zomwe zikuchitika mumagetsi ofanana. Chifukwa chake ngati mphamvu yamagetsi ikakhala yayikulu, timalimbikitsa kugwiritsa ntchito ma MOSFET ofanana pa shunt. Tikasankha MOSFETs kuti tifanane ndi zamakono, ndipo mwa njira imodzi yomwe panopa imadutsa njira ina ya MOSFET yamakono, zamakono za MOSFET zomwe zimayambitsidwa ndi kutentha kwa MOSFETs zazikulu, zomwe zidzachititsa kuti kukana kukhale kokulirapo. , kuchepetsa kutsika kwa magetsi; Ma MOSFET kutengera kusiyana komwe kulipo kuti asinthe nthawi zonse, ndipo pomaliza amazindikira bwino pakati pa ziwiriziZithunzi za MOSFET.
Chimodzi mwa zinthu zomwe tiyenera kuzindikira: ma transistors amathanso kulumikizidwa mofanana kuti amalize kutuluka kwa katundu wamakono, koma muyeneranso kukhazikika pamunsi pa mndandanda wazitsulo zomwe zimayendetsa galimoto kuti zigwirizane ndi zomwe zilipo panopa. ofanana transistor pakati pa vuto.
Mavuto omwe amapezeka pakugwirizana kwa transistor:
(1), chipata cha transistor aliyense sangathe mwachindunji chikugwirizana aliyense pagalimoto resistor mu mndandanda kuchita pagalimoto, pofuna kupewa oscillation.
(2), kusintha transistor iliyonse(MOSFET)nthawi yotseguka ndi nthawi yotseka kuti mukhalebe osasinthasintha, chifukwa ngati sichingafanane, choyamba chitsegule payipi kapena kutseka chitsekocho chidzawonongeka chifukwa cha kulowa mkati mopitirira muyeso.
(3), ndipo potsiriza, tikufuna kuti athe gwero la aliyense transistor mu mndandanda ndi equalizing resistor, ndithudi, si koyenera kuchita, basi.
Olueky wakhala m'modzi mwa othandizira komanso omwe akukula mwachangu ku Asia chifukwa cha chitukuko chamsika chamsika komanso kuphatikiza kwazinthu zothandiza. Kukhala wothandizira wamtengo wapatali kwambiri padziko lapansi ndiolukey ndicholinga.
