Amakilasi we-Car Amplifier

Ama-ABDs we-Car Power Amps

Wonke amps amandla asebenza ngokuyinhloko umsebenzi ofanayo futhi asebenze ngaphansi kwemigomo eyisisekelo efanayo, kodwa lokho akusho ukuthi zonke amakilasi amplifier emoto adalwe alinganayo. Amanye ama-amps angcono kakhulu ekusetshenzisweni okukhethekile kunabanye, futhi indlela elula yokutshela ukuthi yiluphi uhlobo oludingayo ukuthi ubuke ekilasini. Iklasi ngalinye libhekiswe encwadini yama-alfabhethi futhi lichazwe kahle ngokucacile, nakuba kunezinhlanganisela kanye nama-hybrid ahlanganisa izici ezingaphezu kweyodwa.

Inhloko Yekilasi

Ezingeni eliyisisekelo kakhulu, kunezinhlobo ezimbili kuphela zokukhulisa amandla: ama-analog amps nokushintsha amps. Lezi zinhlobo eziyisisekelo ziphinde zaphulwa zibe ngaphezu kwamakilasi aphindwe kabili. Amanye alawa makilasi, afana no-T no-Z, angama-proprietary, imiklamo yokuthengisa, nabanye, njengo-A no-B, bakhiqizwa ngabakhiqizi abahlukahlukene.

Kuzo zonke izigaba ezahlukene zokukhulisa, kunezinhlobo ezine kuphela ezisetshenziselwa izinhlelo zomsindo wezimoto, futhi enye yazo yinto ehlanganisiwe. Lezi zigaba ezine ze-amplifier yi-A, B, AB, no-D.

Amaplifiers e-Class A Car

Ngencazelo, iklasi A amplifiers "njalo." Lezi amps zihlanganiswe ndawonye ngenxa yokuthi basebenzisa izifunda zangaphakathi ezihloswe ukuba kube njalo wamanje edlula transistors okukhiphayo. Lo mklamo oyisisekelo uhambisana nezinzuzo zombili nezimo ezenza iklasi A amps ifaneleke kahle kwezinye izinhlelo zokusebenza futhi ezingafanelanga abanye.

Inkinga enkulu uma kuziwa eklasini A amps emisebenzini yemoto stereo isayizi.

I-Class B Car Amplifiers

Ngokungafani nesigaba se-A amps, ama-amplifiers we-class B amandla ashintshiwe. Lokho kusho ukuthi basebenzisa izifunda zangaphakathi ezibavumela ukuba "baqede" ngokuphumelelayo ukukhishwa kwabo okukhiphayo uma kungekho isignali yomsindo ukukhulisa. Lokhu kubangela ukusebenza kahle okukhulu, okwenza isigaba B sifaneleke ngokufanele emisebenzini yomsindo wezimoto, kodwa futhi siza nokuncipha ukuthembeka kwezwi.

Ama-AB AB Amaplifiers wezimoto

Lezi-amps ziyimpumelelo ye-hybrid yamakilasi wendabuko A no B. Nakuba ama-transistors awo ahlale enezikhathi zamanje, asebenzisa ukujikeleza okukwazi ukunciphisa inani lamanje uma kungekho isignali ekhona. Lokhu kuphumela ngezinga eliphakeme kakhulu lokusebenza kahle kunama-amps afundela ahlanzekile ngaphandle kokuphazamiseka okukhulu njengoklasi B amp. Ngenxa yalezi zinzuzo, ama-amplifiers we-class AB abesebenzisa ama-amps egcwele ngokugcwele emiphakathini yomsindo wezimoto.

Ama-Class D Car Amplifiers

Izigaba ze-Class A, B, ne-AB ziyizibonelo zamakilasi a-analog amplifier, okwenza isigaba D yi-class kuphela "eshintshile" yamaklasi ajwayelekile asetshenziselwa izinhlelo zomsindo wezimoto. Ngokungafani nesigaba A, B no-AB, ama-amps wekilasi D asebenza ngokushintsha nokuvala okwamanje amaphetheli abo ngokushesha.

Lokhu kudala ngokuphumelelayo isignali eshintshiwe, noma i-pulsed, okukhiphayo evezwe kusignali yokufaka i-analog.

Ngenkathi i-class D car amps ephumelela ngokweqile, indlela yokushintsha / ukudonsa inomphumela othile wokuphazamiseka emazingeni aphezulu. Lokhu kuvame ukukhishwa isihlungi esiphansi ngoba ama-frequencies aphansi ahlukumezi okufanayo. Eziningi ze-mono subwoofer amps ziyi-class D, kodwa izinzuzo nezibonelelo zamandla zenza kube omunye wamakilasi athandwa kakhulu okukhulisa amakheli aphelele .

Ngaphandle kwe-A, B, no-D

Ama-amplifiers amaningi alalelwayo angama-A / B noma a-D, kodwa ukuhluka kwalezi zinhlobo ezimbili eziyinhloko nakho kuyatholakala.

Lezi ezinye amakilasi amplifier ngokuvamile zikhetha futhi zikhethe izici ezivela ezinhlobonhlobo ezinkulu ze-amps emzamweni wokwandisa ukusebenza ngaphandle kokudela kakhulu ngokubuyisela.

Ngokwesibonelo, ngendlela efanayo, ukuthi ama-amplifiers e-AB ahlanganisa imiklamo ye-A no-B, ama-amps BD amamitha aklanyelwe ukunikeza ukuphazamiseka okuncane emazingeni aphakeme kunama-amps e-Class D nangokwenza kahle okulindelekile kusuka ekilasini B.

Yisiphi Isigaba Se-Amplifier Kufanele Ukhethe?

Ngokusungulwa kwe-bD, i-GH nezinye izinhlobo zama-amplifiers, ukukhetha iklasi elungile kungabonakala kunzima kakhulu kunanini ngaphambili. Uma ufuna nje umsindo ozwakalayo, ngaphandle kokungena kakhulu, umthetho oyisisekelo wesithupha ungukuthi ama-amplifiers A / B angcono kakhulu ebangeni eligcwele kanye nezikhulumi eziningi, ngenkathi izikhulumi ze-class D zingcono ekushayela i-subwoofers. Ungenza kube nzima kakhulu kunalokho uma uthanda, kodwa ukunamathela kuleso sisekelo esiyisisekelo kuyokubeka endleleni elungile.
