Ibikoresho by'inyongera

Amplifier nigikoresho cyongerera imbaraga imbaraga cyangwa ibimenyetso byinjiza.Igizwe numuyoboro wa elegitoroniki cyangwa transistor, transformateur, nibindi bikoresho byamashanyarazi.Ikoreshwa mu itumanaho, gutangaza, radar, televiziyo, kugenzura byikora n'ibindi bikoresho.

Igikoresho cyongera amplitude cyangwa imbaraga z'ikimenyetso.Nibintu byingenzi byo gutunganya ibimenyetso mubikoresho byikora.Imikorere ya amplification ya amplifier igerwaho nikimenyetso cyo kwinjiza kugirango igenzure ingufu, kandi ingufu zikenewe kugirango amplification zitangwa ningufu.Kumurongo wongerera imbaraga, ibisohoka nibisubiramo no kuzamura ibimenyetso byinjira.Kubyongerewe umurongo utari umurongo, ibisohoka nigikorwa cyo kwinjiza ibimenyetso.Ukurikije ubwinshi bwumubiri wibikoresho byo gutunganya ibimenyetso bigabanijwemo ibyuma byongerera imbaraga, ibyuma byongera amashanyarazi, ibyuma byongera ibikoresho bya elegitoronike, hydraulic amplifier na pneumatic amplifier, muri byo bikoreshwa cyane ni ibyuma byongera ibikoresho bya elegitoroniki.Hamwe no gukwirakwiza ikoranabuhanga rya efflux (reba element efflux), ikoreshwa rya hydraulic cyangwa pneumatic amplifiers ryagiye ryiyongera buhoro buhoro.Ibyuma bya elegitoroniki bigabanijwemo ibyuma byongera imbaraga za vacuum, amplistiers ya tristoriste, ibyuma byongera imbaraga hamwe na magnetiki byongera imbaraga ukurikije ibikoresho bifatika byakoreshejwe, muri byo byongera imbaraga za transistor.Amashanyarazi ya Transistor akoreshwa kenshi mugukoresha ingufu za voltage hamwe no kongera ibimenyetso byubu mubikoresho byikora, cyane cyane muburyo bwo kongera imbaraga imwe hamwe no gusunika gukurura.

Ihame: Imbaraga zongera imbaraga zikoreshwa murwego rwanyuma rwohereza.Igikorwa cyayo ni ukongera imbaraga za signal yumurongo mwinshi wahinduwe kugirango wuzuze ibisabwa byo kohereza ingufu, hanyuma ukayirasa mu kirere unyuze muri antene kugirango umenye neza ko uwakiriye mu gace runaka ashobora kwakira urwego rwibimenyetso rushimishije, kandi ntirukore kubangamira itumanaho ryimiyoboro yegeranye.

Umuvuduko mwinshi wumurongo wa amplifier nikintu cyingenzi cyibikoresho byohereza muri sisitemu yitumanaho.Ukurikije ubugari bwumurongo wacyo ukora, irashobora kugabanywamo imirongo migari-nini-y-imbaraga-y-imbaraga-nini-nini-nini-nini-y-imbaraga.Narrow-band high-frequency power amplifier mubisanzwe ifata umurongo wo gutoranya imirongo hamwe numurimo wo guhitamo inshuro zungurura nkibisohoka, bityo nanone byitwa tuned power amplifier cyangwa resonant power amplifier.Ibisohoka byumuzunguruko mugari wumuvuduko mwinshi wumurongo wumurongo wumurongo woguhindura umurongo cyangwa guhinduranya umurongo mugari, bityo nanone byitwa imbaraga zidasanzwe.Amashanyarazi yihuta cyane ni ubwoko bwigikoresho cyo guhindura ingufu, gihindura ingufu za DC zitangwa n amashanyarazi mumashanyarazi menshi asohoka.Birazwi mugihe cy "Umuyoboro muke wa elegitoroniki Yumuzingi".Ukurikije imiyoboro itandukanye ya Angle, amplifier irashobora kugabanywamo A, B, C ubwoko butatu bwibikorwa.Ibiriho ubu Inguni yo mucyiciro A amplifier ni 360o, ikwiranye nibimenyetso bito hamwe no kongera ingufu nke.Ibiriho ubu Inguni yicyiciro cya B amplifier ni 180o;Icyiciro C amplifier igezweho Inguni iri munsi ya 180o.Byombi B B na C C birakwiriye kubikorwa byimbaraga nyinshi.Ibisohoka imbaraga nubushobozi bwicyiciro C cyakazi nikintu kiri hejuru mubintu bitatu byakazi.Imbaraga zongererwa imbaraga nyinshi zikora mubyiciro C. Nyamara, kugoreka imiterere yumurongo wubu wibyiciro bya C byongerewe imbaraga ni nini cyane kuburyo byakoreshwa mugukwirakwiza ingufu nkeya, kandi birashobora gukoreshwa gusa muburyo bwo kongera ingufu za resonant hamwe nu muzingo uhujwe nku umutwaro.Kubera ubushobozi bwo kuyungurura ubushobozi bwumuzunguruko, imiyoboro yumuzunguruko na voltage biracyari hafi cyane ya sinusoidal waveform kandi kugoreka ni bito cyane.
