Inverter yobuchwephesha idala amathuba angenasiphelo.

Intshayelelo yeInverter

I-inverter sisixhobo sombane esiguqula umsinga oguqukayo ube ngumbane othe ngqo, osetyenziswa ikakhulu ukunika amandla kumthwalo.I-Inverter sisixhobo esiguqula umthombo wombane we-DC ube ngumthombo wombane we-AC.Ingasetyenziswa kwi-microcomputer okanye kwi-single-chip microcomputer inkqubo kunye nesixhobo sokwenza umqondiso.

Abaguquliinokwahlulwa ibe yinqanaba elinye, inqanaba lesithathu kunye ne-full-bridge inverters ngokwenqanaba lamandla.Isigaba esinye kunye nabaguquli besigaba esithathu baqulunqwe ngabaguquli, izihluzi kunye nezihluzi zeLC, kwaye imveliso ye-waveform yi-sine wave;ii-inverters zebhulorho epheleleyo zenziwe ngesekethe yokucoca i-rectifier, i-Schottky diode (PWM) isekethe kunye nesekethe ye-drive, kwaye i-wave waveform yi-square wave.

Abaguquliinokuthi ihlelwe ngokweendidi ezintathu: uhlobo olusisigxina lwe-off-off, uhlobo lolawulo lwendawo efileyo (indlela ye-sine wave) kunye nohlobo lolawulo lokutshintsha (indlela ye-square wave).Ngophuhliso lwetekhnoloji ye-elektroniki yamandla, ii-inverters zisetyenziswa ngokubanzi kwiinkalo ezahlukeneyo.

Iingcamango ezisisiseko

I-inverter sisixhobo sombane sombane esiguqula umsinga othe ngqo ube ngumsinga otshintshanayo.I-inverter iqukethe isiphaluka sokucoca i-rectifier, i-Schottky diode (SOK) isiphaluka kunye nesekethe ye-drive.

I-inverter inokohlulwa ibe yi-inverter esebenzayo kunye ne-inverter esebenzayo, i-inverter esebenzayo, ekwabizwa ngokuba yi-inverter circuit okanye i-voltage regulator circuit, ngokubanzi ngenqanaba lokufaka, inqanaba eliphakathi (LC) filter, inqanaba lokuphuma (rectifier), njl. i-inverter esebenzayo yigalelo lokuguqulwa kwesignali yombane ukuze ufumane i-DC ezinzileyo.

I-inverter ye-passive ngokuqhelekileyo ine-capacitor yembuyekezo kwibhulorho yokulungisa, ngelixa i-inverter esebenzayo ine-inductor yokucoca kwibhuloho yokulungisa.

Isekethe ye-inverter ineenzuzo zobukhulu obuncinci, ubunzima obulula, ukusebenza kakuhle okuphezulu njalo njalo.Yinxalenye ephambili yazo zonke iintlobo zezixhobo zombane zamandla.

Ukuhlelwa

Ngokwe-topology ye-inverter inokwahlulwa ibe yi-inverter egcweleyo, i-push-pull inverter.

Iyakwazi ukwahlula kwi-PWM (i-pulse width modulation) inverter, i-SPWM (i-quadrature signal modulation) inverter kunye ne-SVPWM (i-modulation ye-voltage ye-voltage vector) inverter.

Ngokohlelo lwesekethe yokuqhuba lunokwahlulwa lube yi: half-bridge, push-pull type.

Ngokohlobo lomthwalo, lunokwahlulwa lube lunikezelo lwamandla ombane olukwinqanaba elinye, unikezelo lwamandla ombane amanqanaba amathathu, isiguquli seDC, isihluzi esisebenzayo sombane, njl njl.

Ngokwendlela yokulawula inokwahlulwa ibe: imowudi yangoku kunye nemo yombane.

Indawo yosetyenziso

Ii-inverters zisetyenziswa kakhulu kwimizi-mveliso, izixhobo zomkhosi, i-aerospace kunye namanye amasimi.Ngokomzekelo, kwi-industrial automation, izixhobo zembuyekezo yamandla asebenzayo ikakhulu asetyenziswa kwiinkqubo zamandla zinokuhlengahlengisa unikezelo lwamandla ombane aphezulu, ukuphucula ukusebenza kakuhle kwemveliso, ukonga amandla ombane kunye nokubonelela ngombane ozinzileyo kwimveliso yamashishini;kunxibelelwano, izixhobo zembuyekezo yamandla asebenzayo zingasetyenziselwa ukunyenyisa umbane weenkqubo zombane ophantsi ukuzinzisa phakathi koluhlu olufanelekileyo nokuqonda unxibelelwano lomgama omde;kwezothutho, zingasetyenziswa kwinkqubo yokuqalisa injini yemoto kunye nenkqubo yokutshaja ibhetri yemoto;kwizixhobo zomkhosi, zinokusetyenziswa kunikezelo lwamandla kunye nenkqubo yokulawula ngokuzenzekelayo izixhobo zezixhobo;kwi-aerospace, zingasetyenziswa kwi-injini yenqwelomoya eqala unikezelo lwamandla kunye nonikezelo lwamandla lokutshaja ibhetri.
