Metal-oxide-semiconductor field-effect transistors (MOSFETs) e fetotse indasteri ea lisebelisoa tsa elektroniki, ea fetoha likarolo tse fumanehang hohle lipotolohong tse fapaneng. Leha mosebetsi oa bona oa mantlha e le ho laola le ho holisa mats'oao a motlakase, li-MOSFET le tsona li na le ntho eo hangata e hlokomolohuoang empa e le ea bohlokoa: diode ea kahare ea 'mele. Sengoliloeng sena sa blog se shebisisa lintho tse rarahaneng tsa diode tsa 'mele oa MOSFET, ho lekola maano a ho fokotsa tahlehelo ea bona le ho ntlafatsa ts'ebetso ea potoloho ka kakaretso.
Ho utloisisa Tahlehelo ea 'Mele oa MOSFET Diode
'Mele oa diode, motsoako oa tlhaho oa likokoana-hloko ka har'a sebopeho sa MOSFET, o bonts'a phallo ea hona joale e sa lekanyetsoang, e lumellang hore hona joale ho fete ho tloha ho drain ho ea mohloling empa eseng ka tsela e fapaneng. Le hoja e sebeletsa merero ea bohlokoa, diode ea 'mele e ka hlahisa tahlehelo ea matla e fokotsang katleho ea potoloho.
Litahlehelo tsa Ts'ebetso: Nakong ea boemo ba MOSFET, diode ea 'mele e tsamaisa hona joale ka lehlakoreng le ka morao, e hlahisa mocheso le matla a ho qhala.
Ho Fetola Litahlehelo: Nakong ea phetoho ea MOSFET, diode ea 'mele e tsamaisa hona joale nakong ea ho hlaphoheloa, e lebisang ho tahlehelo e fetohang.
Maano a ho Fokotsa Tahlehelo ea 'Mele ea MOSFET
Ho Khetha Li-MOSFET tse Nepahetseng: Khetha li-MOSFET tse nang le motlakase o tlase oa diode pele 'me u khutlisetse nako ea ho khutlisa ho fokotsa tahlehelo ea ho tsamaisa le ho fetola ka ho latellana.
Ho ntlafatsa Lipontšo tsa Drive: Sebelisa matšoao a nepahetseng a liheke ho fokotsa nako eo diode ea 'mele e e tsamaisang nakong ea ho chencha, ho fokotsa tahlehelo ea switching.
Ho sebelisa Lipotoloho tsa Snubber: Kenya ts'ebetsong li-circuits tsa snubber, tse nang le li-resistors le capacitor, ho qhala matla a bolokiloeng ka li-inductances tsa likokoana-hloko le ho fokotsa li-spikes tsa motlakase, ho fokotsa tahlehelo ea ho fetola.
Parallel Body Diode: Nahana ka ho bapisa diode tsa kantle le diode ea 'mele ho arolelana hona joale le ho fokotsa ho felloa ke matla, haholo lits'ebetsong tsa morao-rao.
Moralo o Mong oa Potoloho: Maemong a mang, li-topologies tse ling tsa potoloho tse felisang tlhoko ea tsela ea ho tsamaisa diode ea 'mele li ka nkoa e le ho fokotsa tahlehelo.
Melemo ea ho Fokotsa Tahlehelo ea Diode ea 'Mele ea MOSFET
Katleho e Ntlafetseng: Ho fokotsa tahlehelo ea diode ea 'mele ho lebisa katlehong e kholo ea potoloho, ho fetolela tšebeliso e tlaase ea matla le ho boloka matla.
Phokotso ea Mocheso o Fokotseng: Ho fokotsa tahlehelo ho fokotsa ho hlahisa mocheso ka har'a MOSFET le likarolo tse potolohileng, ho ntlafatsa ts'ebetso ea mocheso le ho atolosa nako ea bophelo ea karolo.
Tšepahala e Ntlafetseng: Lithempereichara tse tlase tsa ts'ebetso le khatello e fokotsehileng ea khatello ea likarolo li kenya letsoho ho matlafatseng ho ts'epahala ha potoloho le bophelo bo bolelele.
Qetello
Li-diode tsa 'mele tsa MOSFET, leha hangata li hlokomolohuoa, li ka ama haholo ts'ebetso ea potoloho le ts'ebetso. Ho utloisisa mehloli ea tahlehelo ea diode ea 'mele le ho kenya ts'ebetsong maano a ho fokotsa ho bohlokoa bakeng sa ho rala lisebelisoa tsa elektroniki tse sebetsang hantle, tse tšepahalang. Ka ho sebelisa mekhoa ena, baenjiniere ba ka ntlafatsa ts'ebetso ea potoloho, ba fokotsa tšebeliso ea matla, le ho lelefatsa nako ea bophelo ea meralo ea bona ea elektroniki.
