Iyini i-adaptha yamandla?

Noma iyiphi impahla kagesi idinga i-adaptha yamandla ye-DC ukuze inikeze isekethe, ikakhulukazi imikhiqizo ye-elekthronikhi enikwa amandla i-adaptha yamandla egridi. Ukuze uvumelane nokuguquguquka kwamandla kagesi wegridi kanye nokushintsha kwesimo sokusebenza sesekethe, kubaluleke kakhulu ukuthi kube ne-adaptha yamandla elawulwa yi-DC ukuze ivumelane nokushintsha kwamandla kagesi wegridi nomthwalo. I-adaptha elawulwayo yokuhlinzeka amandla ibona ukuguqulwa kwamandla kagesi kanye nokuzinza kwamandla kagesi ngokuguqula i-DC ibe yi-high-frequency pulse kanye nokuguqulwa kwe-electromagnetic. I-adaptha yamandla elawulwa ngomugqa ixhunywe ngokuqondile ochungechungeni ngento elungiswayo elawulekayo ukuze ihlukanise i-voltage ye-DC yokufaka ukuze kubonakale ukuguqulwa kwe-voltage nokuzinza kwe-voltage. Empeleni, ilingana nokuxhuma i-resistor eguquguqukayo ochungechungeni.

I-adaptha elawulwayo yokunikezwa kwamandla iyasebenza kakhulu futhi ingakhuphula noma icindezele. I-adaptha yamandla elawulwayo inganciphisa kuphela i-voltage futhi isebenze kahle kancane. Ukushintsha i-adaptha yamandla elawulwayo kuzokhiqiza ukuphazamiseka kwemvamisa ephezulu, kuyilapho i-adaptha yamandla elawulwa ngomugqa ngeke ibe nokuphazamiseka. Ngayinye inezinzuzo zayo kanye nokubi.

Eminyakeni yamuva nje, ngokuthuthukiswa kobuchwepheshe be-elekthronikhi kanye nocwaningo lwabantu lwendlela yokuthuthukisa ukusebenza kahle kokuguqulwa kwe-adaptha yamandla elawulwayo, ukuthuthukisa ukuguquguquka kwegridi yamandla, ukunciphisa ivolumu nokunciphisa isisindo, i-adaptha yamandla yaba khona. Ngawo-1970, i-adaptha yamandla yasetshenziswa kumamukeli we-TV wasendlini. Manje isisetshenziswe kabanzi kumabonakude wemibala, ikhamera yevidiyo, ikhompuyutha, uhlelo lokuxhumana, imishini yezokwelapha, i-meteorology nezinye izimboni, futhi kancane kancane yashintsha uchungechunge lwendabuko olulawulwa yi-adaptha yamandla elawulwayo, ukuze ukusebenza, ukusebenza kahle nokuthembeka kwawo wonke umshini ube nawo. ithuthukisiwe.

Uchungechunge olujwayelekile lwama-adaptha wamandla alawulwayo afakwe ama-adaptha aguquguqukayo, anezinzuzo ze-voltage ephumayo ezinzile kanye ne-ripple encane, kodwa ububanzi bamandla kagesi buncane futhi ukusebenza kahle kuphansi. I-voltage ephumayo ye-adaptha yamandla elawulwa ngokuhambisana izinzile ikakhulukazi, kodwa umthamo wokulayisha uphansi kakhulu. Ngokuvamile, isetshenziswa kuphela njengereferensi ngaphakathi kwethuluzi.
