Yintoni iadaptha yamandla?

Nasiphi na isixhobo sombane sidinga iadaptha yamandla yeDC ukubonelela ngesekethe, ngakumbi iimveliso zombane eziqhutywa yiadaptha yamandla egridi. Ukuze ulungelelanise ukuguquguquka kwamandla ombane wegridi kunye notshintsho lwemo yokusebenza yesekethe, kuyimfuneko ngakumbi ukuba i-DC elawulwa yi-adaptha yamandla ukulungelelanisa nokutshintsha kombane wegridi kunye nomthwalo. I-adaptha yonikezelo lombane elawulayo elawulayo iqonda ukuguqulwa kwamandla ombane kunye nokuzinziswa kwamandla ombane ngokuguqula i-DC ibe yi-high-frequency pulse kunye nokuguqulwa kwe-electromagnetic. I-adaptha yamandla elawulwa ngumgca iqhagamshelwe ngokuthe ngqo kuthotho kunye nesixhobo esilawulekayo sokulungelelanisa ukwahlula igalelo lombane weDC ukuqonda uguqulo lombane kunye nokuzinzisa umbane. Ngokwenyani, ilingana nokudibanisa i-resistor eguquguqukayo kuthotho.

Ukutshintshwa kwe-adapter yonikezelo lwamandla elawulwayo kunokusebenza okuphezulu kwaye kunokunyusa okanye ukudandatheka. I-adaptha yamandla elawulwa ngumgca inokunciphisa amandla ombane kwaye inokusebenza okuphantsi. Ukutshintshela i-adaptha yamandla elawulwayo kuya kuvelisa uphazamiseko lwe-high-frequency, ngelixa i-adaptha yamandla elawulwa ngumgca ayiyi kuba nokuphazamiseka. Nganye ineengenelo zayo kunye nezinto ezingeloncedo ngayo.

Kwiminyaka yakutshanje, ngophuhliso lwetekhnoloji ye-elektroniki kunye nophando lwabantu malunga nendlela yokuphucula ukusebenza kakuhle kweadaptha yamandla elawulwayo, ukuphucula ukuguquguquka kwigridi yamandla, ukunciphisa umthamo kunye nokunciphisa ubunzima, iadaptha yamandla yabakho. Ngeminyaka yee-1970, i-adapter yamandla yasetyenziswa kwi-TV yendlu. Ngoku isetyenziswe ngokubanzi kumabonakude wemibala, ikhamera yevidiyo, ikhompyuter, inkqubo yonxibelelwano, izixhobo zonyango, i-meteorology kunye namanye amashishini, kwaye ngokuthe ngcembe ithathe indawo yeadaptha yamandla elawulwayo yemveli, ukuze ukusebenza, ukusebenza kakuhle kunye nokuthembeka kwawo wonke umatshini. iphuculwe ngakumbi.

Iiadaptha zamandla ezilungelelanisiweyo ezilawulwayo zixhotyiswe nge-adaptha ye-adaptha yamandla, enenzuzo yombane wokuphuma okuzinzileyo kunye ne-ripple encinci, kodwa uluhlu lombane luncinci kwaye ukusebenza kakuhle kuphantsi. Umbane wemveliso we-parallel elawulwayo iadaptha yamandla uzinzile ngokukodwa, kodwa umthamo womthwalo umbi kakhulu. Ngokuqhelekileyo, isetyenziswa kuphela njengesalathiso ngaphakathi kwesixhobo.
