Amasekhethi okuphakela amandla, noma amasekhethi okuphakela amandla emkhakheni we-propulsion, asetshenziswa nakanjaniAma-MOSFET, okuyizinhlobo eziningi futhi ezinemisebenzi eminingi. Ukushintsha ukunikezwa kwamandla noma izinhlelo zokusebenza zokuhambisa, kungokwemvelo ukusebenzisa umsebenzi wayo wokushintsha.
Ngaphandle kohlobo lwe-N noma uhlobo lwe-PI-MOSFET, umgomo uyafana, i-MOSFET yengezwa esangweni lokuphela kwesibopho samanje ukuze kulawulwe uhlangothi oluphumayo lwe-drain current, i-MOSFET iyidivayisi elawulwa yi-voltage esekelwe okwamanje engezwe esangweni ku-drain current. ukuxhashazwa kwezici zedivayisi, akujwayele ukushintsha njenge-transistor ngenxa yesisekelo samanje esibangelwa umphumela omuhle wesitoreji, ngakho-ke, ohlelweni lokushintsha, izinga lokushintsha le-MOSFET kufanele lisheshe kune-transistor. Izinga lokushintsha kufanele lisheshe kune-triode.
I-MOSFETizimbangela zokushisa zamanje ezincane
1, umgomo wesekethe wenkinga ukuvumela i-MOSFET ukuthi isebenze esimweni sokusebenza esilandelanayo, hhayi esimweni sokushintshwa. Lokhu futhi kuyimbangela yokushisa kwe-MOSFET. Uma ukushintsha kwe-N-MOS, i-voltage yokusebenza yeleveli ye-G kunogesi oshintshayo ongu-V embalwa, ukuze uvule futhi ucishwe ngokuphelele, i-P-MOS ingenye indlela. Akuvuliwe ngokuphelele futhi ukulahlekelwa kukhulu kakhulu okuholela ekulahlekeni kwamandla okukhiphayo, i-impedance yesici yesekethe efanayo ye-DC inkulu, ukulahlekelwa kuyanwetshwa, ngakho-ke i-U * I nayo iyanwetshwa, ukuncipha kumelela ukushisa. Lona futhi umjikelezo wokulawula uhlelo olungalungile olugwenywe kakhulu.
2, imvamisa iphezulu kakhulu, ikakhulukazi kwesinye isikhathi ukuphishekela ivolumu ephelele kakhulu, okuholela ekuthuthukisweni kwemvamisa, i-MOSFET ekwandeni kokusetshenziswa, ngakho-ke ukushisa nakho kukhuphuke.
I-3, ayizange yenze uhlelo lokuklama okwanele lokungabandakanyi ukushisa, okwamanje kuphezulu kakhulu, inani lamanje lokubekezelela i-MOSFET, ngokuvamile kufanele kugcinwe ukukhishwa okuhle kokushisa kungenziwa. Ngakho-ke, i-ID iphansi kuneyamanje ephezulu, futhi kungenzeka ukuthi ifudumale kakhulu, kufanele yanele ukusiza usinki wokushisa.
I-4, ukukhethwa kwemodeli ye-MOSFET akulungile, amandla okukhiphayo awalungile, ukumelana kwe-MOSFET akunakwa, okuholela ekwandeni kokuphazamiseka kwesici sokushintsha.
Ukushisisa okuncane kwe-MOSFET kubucayi kakhulu ukuthi kuxazululwa kanjani?
1.thola uhlelo lwedizayini yokukhishwa kokushisa kwe-MOSFET, siza inombolo ethile yamasinki okushisa.
2.Namathisela iglue yokukhishwa kokushisa.
