Kusanthula kwazifukwa za kusagwira ntchito kwa MOSFET

Panthawi imeneyi pakugwiritsa ntchito makampani, kugwiritsa ntchito zida za adaputala zoyambira pagulu la ogula zamagetsi. Pamalo achiwiri ndi mavabodi apakompyuta, ma adapter apakompyuta, zowunikira za LCD ndi zinthu zina. Chachitatu ndi maukonde olankhulana, makina owongolera mafakitale, zamagetsi zamagalimoto ndi zida zina zamagetsi. Zogulitsa izi zomwe zimafunikira MOSFET ndizokuliraponso, makamaka zamagetsi zamagalimoto zamagalimoto masiku ano zomwe zimafunikira MOSFET zikuwoneka kuti zikugwirizana ndi kufunikira kwamagetsi ogula.
Kuchokera ku chitsanzo pamwambapa, titha kumvetsetsa kufunikira kwa ma MOSFET mdziko muno kunayamba kupitiliza kukula, koma kugwiritsa ntchitoZithunzi za MOSFETaliyense akumvetsa zifukwa zomwe MOSFETs ndi osagwira ntchito? Kenako, ndikuwonetsa zifukwa zisanu ndi chimodzi zakulephera kwa MOSFET:

1, kulephera kwamagetsi nthawi zambiri kumanenedwa kuti kutayikira pakati pa gwero la voteji ya BVdss kumapitilira voteji ya mosfet, komanso kupitilira kuthekera kwina komwe kungayambitse kulephera kwa mosfet.

2, kulephera kwapano komwe kuli kopitilira muyeso wotetezeka wa mosfet ndi wosavomerezeka, womwe umagawidwa mu Id umaposa zomwe zidachitika ndipo kulephera komwe kumachitika chifukwa cha ID yake ndikokulirapo, kutha kung'ambika komanso kung'ambika komwe kumabweretsa kudzikundikira kwa nthawi yayitali kwa matenthedwe. chipangizo ndi kulephera.

3, mu mlatho, LLC ndi zina zogwira mtima ku diode ya thupi kuti ikwaniritse ma topology apano, chifukwa diode yathupi yawonongeka komanso yosavomerezeka.

4, munjira yofananira yogwiritsira ntchito, chipata chokhala ndi magawo a parasitic wozungulira chimayambitsa kusinthasintha kungayambitse kulephera kwa resonance.

5, pamalo owuma, chifukwa thupi la munthu ndi zida ndi magetsi osasunthika opangidwa ndi chipangizocho zipangitsa kuti static isagwire ntchito.

6. Mphamvu yamagetsi pachipata ndi yosavomerezeka chifukwa champhamvu yamagetsi yamagetsi pachipata.

Zomwe zili pamwambazi zachokeraMOSFETkuwunika zomwe zimayambitsa kulephera, timapanga magwiridwe antchito ofananira, pali zina zolandilidwa kuti mutifunse pa intaneti kampani ya Guanhua Weiye, ingakupatseni mayankho ogwira mtima komanso malingaliro abwino a utumiki.
olukeykampani kupulumuka ngongole, kutsatira "khalidwe loyamba, utumiki woyamba" cholinga ndi mabizinezi zambiri zamakono kunyumba ndi kunja, fakitale choyambirira kukhazikitsa ubwenzi wabwino, ndi zaka zambiri akatswiri zinachitikira kugawa, ndi ngongole zabwino, ntchito yabwino kwambiri, kupeza kudalirika kosiyanasiyana ndi chithandizo.
