Ndeapi maparamita andinofanira kutarisisa pakusarudza Triode uye MOSFET?

Zvigadzirwa zvemagetsi zvine magetsi emagetsi, uye zvakakosha kusiya muganhu wakakwana wezvikamu zvemagetsi pakusarudza rudzi rwekusimbisa kugadzikana uye kushanda kwenguva refu kwezvikamu zvemagetsi. Tevere suma muchidimbu nzira yekusarudza yeTriode uye MOSFET.

Triode mudziyo unodzorwa-kuyerera, MOSFET mudziyo unodzorwa nemagetsi, pane zvakafanana pakati pezviviri izvi, pakusarudza kwechido chekufunga nezvekutsungirira voltage, ikozvino uye mamwe ma paramita.

 

1, zvinoenderana neyakakura inomira kusarudzwa kwemagetsi

Triode muunganidzi C uye emitter E inogona kumira nemhepo yakakura pakati peparameter V (BR) CEO, iyo voltage pakati peEC panguva yekushanda haingapfuuri kukosha kwakatarwa, zvikasadaro Triode ichakuvadzwa zvachose.

Iyo yakanyanya voltage iripo zvakare pakati peiyo D uye sosi S yeMOSFET panguva yekushandiswa, uye voltage paDS panguva yekushanda haifanire kudarika kukosha kwakatarwa. Kazhinji kutaura, iyo voltage inomira kukosha kweMOSFETyakakwira zvakanyanya kupfuura Triode.

 

2, iyo yakanyanya overcurrent kugona

Triode ine ICM parameter, kureva, muunganidzi overcurrent kugona, uye overcurrent kugona kweMOSFET kunoratidzwa maererano neID. Kana iko iko kushanda, ikozvino inoyerera kuburikidza neTriode / MOSFET haigoni kudarika kukosha kwakatarwa, zvikasadaro mudziyo uchapiswa.

Tichifunga nezve kugadzikana kwekushanda, muganho we30% -50% kana kutopfuura unobvumidzwa.

3,Kushanda tembiricha

Commerce-giredhi machipisi: general range ye0 kusvika +70 ℃;

Industrial-giredhi machipisi: huwandu hwakawanda hwe -40 kusvika +85 ℃;

Military giredhi machipisi: general range ye -55 ℃ kusvika +150 ℃;

Paunenge uchisarudza MOSFET, sarudza chip yakakodzera maererano nechiitiko chekushandiswa kwechigadzirwa.

 

4, zvinoenderana neiyo switching frequency kusarudzwa

Zvose Triode uyeMOSFETiva nemiganhu yekuchinja frequency / yekupindura nguva. Kana yakashandiswa mumatunhu akakwirira-frequency, nguva yekupindura yechubhu yekushandura inofanira kuonekwa kuti inosangana nemamiriro ekushandiswa.

 

5,Mamwe mamiriro ekusarudza

Semuenzaniso, iyo on-resistance Ron parameter yeMOSFET, iyo VTH yekutendeuka-on voltage yeMOSFET, zvichingoenda zvakadaro.

 

Wese munhu ari muMOSFET kusarudzwa, unogona kusanganisa ari pamusoro mapoinzi ekusarudza.
