Ho Utloisisa Pulse Rectifiers le Polarity Reverse Rectifiers

Liphapang tsa Bohlokoa le Lisebelisoa

Li-rectifiers ke likarolo tsa bohlokoa lipotolohong tse fapaneng tsa elektroniki le lits'ebetso tsa phepelo ea motlakase. Ba fetola alternating current (AC) ho tsamaisa hona joale (DC), ho fana ka matla a hlokahalang bakeng sa lisebelisoa tse ngata le lisebelisoa. Har'a mefuta e fapaneng ea li-rectifiers, li-pulse rectifiers le polarity reverse rectifiers li tsebahala ka litšobotsi tsa tsona tse ikhethang le ts'ebeliso. Sengoliloeng sena se shebana le phapang lipakeng tsa mefuta ena e 'meli ea li-rectifiers, melao-motheo ea bona ea ts'ebetso, melemo, mathata le ts'ebeliso.

Li-Pulse Rectifiers

Li-pulse rectifiers, tse tsejoang hape e le li-pulsed rectifiers kapa rectifiers tse laoloang, ke lisebelisoa tse fetolelang AC ho DC ka ho sebelisa lisebelisoa tse laoloang tsa semiconductor tse kang thyristors kapa silicon-controlled rectifiers (SCRs). Li-rectifiers tsena hangata li sebelisoa lits'ebetsong tse hlokang taolo e nepahetseng holim'a matla a motlakase le a hona joale.

Molao-motheo oa ho Sebetsa

Ts'ebetso ea "pulse rectifier" e kenyelletsa ho laola sekhahla sa motlakase oa AC. Ka ho fetola sekhahla sa "triggering angle" sa SCRs, motlakase oa DC o ka laoloa. Ha SCR e qala, e lumella hona joale hore e fete ho fihlela potoloho ea AC e fihla ho zero, ka nako eo SCR e tima. Ts'ebetso ena e pheta-pheta bakeng sa potoloho e 'ngoe le e' ngoe ea karolo ea AC, e hlahisa tlhahiso ea DC.

Melemo

Taolo e Nepahetseng: Li-Pulse rectifiers li fana ka taolo e ntle holim'a motlakase o hlahisoang le oa hajoale, li li etsa tse loketseng lits'ebetso tse hlokang tlhahiso e feto-fetohang ea DC.

Sebetsa se Phahameng: Li-rectifiers tsena li sebetsa hantle haholo, kaha li fokotsa tahlehelo ea matla nakong ea phetoho.

Ho feto-fetoha ha maemo: Li-pulse rectifiers li khona ho sebetsana le meroalo e fapaneng 'me li loketse mefuta e fapaneng ea lisebelisoa tsa AC.

Mefokolo

Ho rarahana: Potoloho ea li-pulse rectifiers e rarahane ho feta ea li-rectifiers tse bonolo, tse hlokang likarolo tse ling bakeng sa ho qala le ho laola.

Litšenyehelo: Ka lebaka la ts'ebeliso ea lisebelisoa tse laoloang tsa semiconductor le li-circuits tsa taolo tse eketsehileng, li-pulse rectifier hangata li bitsa chelete e ngata.

Lisebelisoa

Li-rectifiers tsa Pulse li sebelisoa haholo lits'ebetsong tsa indasteri, ho kenyelletsa:

1.Li-driable Speed ​​​​Drives: Bakeng sa ho laola lebelo la li-motors tsa AC.

2.Lisebelisoa tsa Motlakase: Ka lisebelisoa tsa motlakase tse laoloang bakeng sa lisebelisoa tsa elektroniki.

3.Welding: Ka thepa ea tjheseletsa moo taolo e nepahetseng ea tlhahiso ea hona joale e leng bohlokoa.

4.Phetiso ea HVDC: Lits'ebetsong tsa phetisetso ea motlakase oa motlakase o phahameng haholo (HVDC) bakeng sa katleho

Li-rectifiers tsa polarity

Li-reverse rectifiers tsa polarity, tse tsejoang hape e le li-reverse polarity protection rectifiers kapa reverse voltage protection rectifiers, li etselitsoe ho sireletsa lipotoloho tšenyong e bakiloeng ke likhokahano tse fosahetseng tsa polarity. Ba etsa bonnete ba hore potoloho e sebetsa ka nepo le haeba polarity ea phepelo ea motlakase e khutlisetsoa morao.

Molao-motheo oa ho Sebetsa

Karolo ea mantlha ea polarity reverse rectifier ke diode kapa motsoako oa diode. Ha e kopantsoe letoto le phepelo ea matla, diode e lumella hona joale hore e phalle ka tsela e nepahetseng feela. Haeba polarity e fetoha, diode e thibela hona joale, e thibela tšenyo ea potoloho.

Meralong e tsoetseng pele ho feta, li-MOSFET (metal-oxide-semiconductor field-effect transistors) li sebelisoa ho fana ka ho theoha ho tlase ha motlakase o eang pele le ho sebetsa hantle haholo ha ho bapisoa le diode. Li-rectifiers tsena tse thehiloeng ho MOSFET li ikamahanya le polarity e nepahetseng le ho netefatsa ts'ebetso e nepahetseng ea potoloho.

Melemo

Tšireletso ea Potoloho: Li-reverse rectifiers tsa polarity li sireletsa ka katleho likarolo tsa elektronike tse tebileng hore li se ke tsa senyeha ka lebaka la likhokahano tse fosahetseng tsa polarity.

Bonolo: Moqapi o batla o le bonolo 'me o ka kopanngoa habonolo le lipotoloho tse teng.

E na le Litšenyehelo: Li-rectifiers tsa polarity reverse tse thehiloeng ho diode ha li turu ebile li fumaneha habonolo.

Mefokolo

Voltage Drop: Li-rectifiers tse thehiloeng ho diode li hlahisa ho theoha ha matla a pele, ho ka fokotsang katleho ea potoloho.

Taolo e Lekanyelitsoeng: Li-rectifiers tsena ha li fane ka taolo holim'a motlakase o tsoang kapa oa hona joale, kaha mosebetsi oa bona oa mantlha ke ts'ireletso.

Lisebelisoa

Li-reverse rectifiers tsa polarity li sebelisoa lits'ebetsong tse fapaneng moo tšireletso khahlanong le polarity e fapaneng e leng bohlokoa, ho kenyelletsa:

1.Consumer Electronics: Ka har'a lisebelisoa tse kang li-smartphone, li-laptops, le lisebelisoa tse ling tsa elektronike tse nkehang habonolo ho thibela tšenyo e bakoang ke likhokahano tse fosahetseng tsa phepelo ea motlakase.

2.Likoloi: Ka lisebelisoa tsa elektroniki tsa likoloi ho sireletsa li-circuits ho likhokahano tsa betri tse ka morao.

3.Solar Power Systems: Ho netefatsa ts'ebetso e nepahetseng ea liphanele tsa letsatsi le ho thibela tšenyo e tsoang ho polarity e ka morao.

4.Li-charger tsa Battery: Ho sireletsa li-circuits tsa ho tjhaja likhokelong tse fosahetseng tsa betri.

Qetello

Li-pulse rectifiers le polarity reverse rectifiers ke likarolo tsa bohlokoa lits'ebetsong tsa sejoale-joale tsa elektroniki, e 'ngoe le e 'ngoe e na le sepheo se ikhethileng. Li-rectifiers tsa Pulse li fana ka taolo e nepahetseng le ts'ebetso e nepahetseng phetohong ea AC ho ea ho DC, e li etsang hore li tšoanelehe bakeng sa lits'ebetso tsa indasteri. Ka lehlakoreng le leng, li-reverse rectifiers tsa polarity li fana ka tšireletso ea bohlokoa khahlanong le likhokahano tse fosahetseng tsa polarity, ho netefatsa polokeho le ts'epahalo ea lisebelisoa le litsamaiso tse fapaneng tsa elektroniki. Ho utloisisa phapang lipakeng tsa li-rectifiers tsena ho thusa ho khetha karolo e nepahetseng bakeng sa lits'ebetso tse ikhethileng, qetellong ho ntlafatsa ts'ebetso le bophelo bo bolelele ba lipotoloho tsa elektroniki.
