Tsananguro yakadzama yemusimboti wekushanda wesimba repamusoro MOSFET

High-power MOSFETs (metal-oxide-semiconductor field-effect transistors) inoita basa rakakosha muinjiniya yemazuva ano yemagetsi. Ichi chishandiso chave chinhu chakakosha mumagetsi emagetsi uye yakakwirira-simba maapplication nekuda kwekuita kwayo kwakanaka uye kwakasiyana maapplication. Chinyorwa ichi chichaongorora misimboti yekushanda kwe-high-simba MOSFETs kupa mainjiniya nevanofarira zvemagetsi kunzwisisa kwakadzama uye kwakadzama.

Chii chinonzi high power MOSFET?

High power MOSFET is a semiconductor switch inokwanisa kubata yakakwira ikozvino uye yakakwirira voltage. Inoumbwa nezvikamu zvitatu zvikuru: Kwakabva, Draini uye Gedhi. Gedhi rakaparadzaniswa nekwakabva uye rinodonhedzwa neyakaonda oxide layer, inova iyo "oxide" chikamu chechimiro cheMOS.

Simba rakakwirira sei MOSFET inoshanda

Iyo yekushanda musimboti wepamusoro-simba MOSFET yakavakirwa pakutonga kwemagetsi munda. Kana mhepo yekumberi ichiiswa pakati pegedhi uye sosi, chiteshi chekufambisa chinoumbwa mune semiconductor zvinhu pasi pegedhi, ichibatanidza kwainobva uye kudonhedza, ichibvumira ikozvino kuyerera. Nekugadzirisa magetsi egedhi, tinogona kudzora maitiro eiyo conductive chiteshi, nekudaro tichiwana kunyatso kudzora kwezvino.

Iyi yemagetsi yekudzora munda wemagetsi inopa MOSFET akawanda mabhenefiti, anosanganisira yakaderera pa-resistance, yakakwirira-kumhanya switching kugona uye yakakwirira yekupinza impedance. Aya maitiro anoita epamusoro-simba MOSFETs kunyanya akakodzera kune maapplication anoda hunyanzvi hwepamusoro uye nekukurumidza kupindura.

Zvakanakira zvesimba repamusoro MOSFETs

Kunyanya kushanda zvakanaka: Nekuda kwekudzikira-kupokana, epamusoro-simba MOSFETs anoshandisa simba shoma mu-nyika, nekudaro achivandudza kuita kwese.

Kuchinja nekukurumidza: High-power MOSFETs inogona kushandura kubva kudzima ichienda munguva pfupi yakanyanyisa yenguva, iyo yakakosha ku frequency kutendeuka uye pulse-width modulation (PWM) control.

High-frequency operation: Vanokwanisa kushanda pamatunhu akakwirira, zvichiita kuti magetsi ekushandura ave maduku uye anoshanda zvakanyanya.

Nzvimbo dzekushandisa

High-simba MOSFETs anoshandiswa zvakanyanya mumhando dzakasiyana-siyana dzemagetsi emagetsi, senge mota dzemagetsi, masisitimu emagetsi anovandudzwa, magetsi ekuchinja, uye maindasitiri otomatiki emidziyo.

Pfupisa

High-power MOSFETs yave chikamu chakakosha chemazuva ano tekinoroji tekinoroji nekuda kwekuita kwavo kwakanaka uye kuchinjika mashandisirwo. Nekunzwisisa misimboti yayo yekushanda uye mabhenefiti, mainjiniya nevagadziri vanogona kushandisa zvirinani mudziyo une simba uyu kuunza zvakanyanya kushanda uye zvakavimbika zvigadziriso zvemagetsi kupasi. Izvi hazvikurudziri kufambira mberi kwetekinoroji, asi zvakare zvinounza kurerukirwa kuhupenyu hwedu hwezuva nezuva.
