Isingeniso sikaI-Inverter
I-inverter iyithuluzi likagesi eliguqula i-alternating current ibe yi-direct current, esetshenziswa kakhulu ukunikeza amandla kumthwalo. I-Inverter iyithuluzi eliguqula umthombo we-DC voltage ube umthombo we-AC voltage. Ingasetshenziswa kukhompyutha encane noma ohlelweni lwekhompyutha encane kanye nemishini yokucubungula isignali.
Ama-Inverteringahlukaniswa ibe ama-inverter esigaba esisodwa, esigaba sesithathu kanye nama-bridge agcwele ngokwezinga lamandla. Ama-inverter esigaba esisodwa kanye nesigaba sesithathu akhiwe ngama-transformer, izihlungi kanye nezihlungi ze-LC, kanti i-output waveform iyi-sine wave; ama-full-bridge inverter akhiwe yi-rectifier filter circuit, i-Schottky diode (PWM) circuit kanye ne-drive circuit, kanti i-output waveform iyi-square wave.
Ama-Inverterzingahlukaniswa ngezinhlobo ezintathu: uhlobo oluqinile oluvuliwe, uhlobo lokulawula oluyi-dead-zone (umzila we-sine wave) kanye nohlobo lokulawula iswishi (umzila we-square wave). Ngokuthuthuka kobuchwepheshe be-elekthronikhi yamandla, ama-inverter asetshenziswa kabanzi emikhakheni eyahlukahlukene.
Imiqondo eyisisekelo
I-inverter iyithuluzi likagesi elinamandla eliguqula i-direct current ibe yi-alternating current. I-inverter iqukethe i-rectifier filter circuit, i-Schottky diode (SOK) circuit kanye ne-drive circuit.
I-inverter ingahlukaniswa ibe yi-inverter esebenzayo kanye ne-inverter engasebenzi, i-inverter engasebenzi, eyaziwa nangokuthi isekethe ye-inverter noma isekethe yokulawula i-voltage, ngokuvamile ngesigaba sokufaka, isihlungi sesigaba esiphakathi (LC), isigaba sokukhipha (i-rectifier), njll., kanti i-inverter esebenzayo ingukuguqulwa kwesignali ye-voltage yokufaka ukuze kutholakale i-voltage ye-DC ezinzile.
I-inverter engasebenzi ivame ukuba ne-capacitor yesinxephezelo ebhulohweni lokulungisa, kuyilapho i-inverter esebenzayo ine-inductor yesihlungi ebhulohweni lokulungisa.
Isekethe ye-inverter inezinzuzo zobukhulu obuncane, isisindo esilula, ukusebenza kahle okuphezulu njalo njalo. Iyingxenye ebalulekile yazo zonke izinhlobo zemishini kagesi enamandla.
Ukuhlukaniswa
Ngokusho kwe-topology ye-inverter ingahlukaniswa ibe yi: i-inverter egcwele ibhuloho, i-inverter ecindezelayo.
Ingahlukaniswa ibe yi-inverter ye-PWM (pulse width modulation), i-inverter ye-SPWM (quadrature signal modulation) kanye ne-inverter ye-SVPWM (space voltage vector modulation).
Ngokusho kwesigaba sokushayela, ukuhlukaniswa kwesekethe yokushayela kungahlukaniswa kube: uhlobo lwe-half-bridge, uhlobo lwe-push-pull.
Ngokusho kohlobo lomthwalo, ingahlukaniswa ngogesi we-inverter wesigaba esisodwa, ugesi we-inverter wesigaba esithathu, i-DC converter, ugesi we-inverter wesihlungi esisebenzayo, njll.
Ngokusho kwemodi yokulawula ingahlukaniswa ibe yi: imodi yamanje kanye nemodi ye-voltage.
Insimu Yesicelo
Ama-inverter asetshenziswa kabanzi emishinini yezimboni, imishini yezempi, izindiza kanye neminye imikhakha. Isibonelo, emishinini yezimboni, amadivayisi okunciphisa amandla asabelayo asetshenziswa kakhulu ezinhlelweni zamandla angalungisa ukunikezwa kwamandla aphezulu, athuthukise ukusebenza kahle kokukhiqiza, onge amandla kagesi futhi ahlinzeke ngokunikezwa kwamandla okuzinzile kokukhiqiza kwezimboni; ekuxhumaneni, amadivayisi okunciphisa amandla asabelayo angasetshenziswa ukulungisa i-voltage yezinhlelo ze-voltage ephansi ukuze azinze ngaphakathi kobubanzi obufanele futhi afeze ukuxhumana okude; kwezokuthutha, angasetshenziswa ohlelweni lokuqala injini yezimoto kanye nohlelo lokushaja ibhethri yezimoto; emishinini yezempi, angasetshenziswa ohlelweni lokulawula amandla kanye nolwe-othomathikhi lwemishini yezikhali; ezindizayo, angasetshenziswa ekuhlinzekweni kwamandla okuqala injini yezindiza kanye nokunikezwa kwamandla okushaja ibhethri.
