Amandla ombane emveliso yeeadaptha ze-AC DC kufuneka afane nomlinganiselo olinganisiweyo wombane wegalelo lomthwalo (isixhobo esiphathwayo), okanye ngaphakathi koluhlu lwamandla ombane anokumelana nomthwalo (isixhobo esiphathwayo) ngaphandle koko, umthwalo (isixhobo esiphathwayo) sinokumelana nomthwalo (isixhobo esiphathwayo) zitshiswe;
3. Imveliso yangoku yeeadaptha ze-ac dc kufuneka ilingane okanye ibe nkulu kunomthamo wangoku womthwalo (isixhobo esiphathwayo) ukunika amandla awoneleyo;
Yintoni eyenza iiadaptha ze-ac dc ezilungileyo?
Xa sifundile malunga nokusetyenziswa kweeadaptha ze-AC DC, kufuneka sazi ukuba sinokukhetha njani iiadaptha ezilungileyo ze-AC DC.I-adapter elungileyo inokunceda iprojekthi yakho iphumelele impumelelo enkulu
Ukuthembeka kweeadaptha zeDC
Ngokomsebenzi ophambili weeadaptha ze-ac dc, ezifana nokukhusela i-overcurrent, umthombo we-EMI radiation, i-voltage offset esebenzayo, ukunyanzeliswa kwe-harmonic distortion, ukulayisha okunqamlezayo, ukuphindaphinda kwewotshi, ukubonwa okuguquguqukayo, njl., kuchongwa ukuba iadaptha yamandla inokusebenza kakuhle. ixesha elide.
Ukulungeleka kweeadaptha zeDC
Ubulula yenye yezinto zokuqala ekufuneka wonke umntu azithathele ingqalelo.Izixhobo ze-elektroniki zikhula ngokuthe ngcembe kwicala elincinci kwaye eligqwesileyo.Ewe kunjalo, kukwanjalo nakwiiadaptha ze-ac dc.Ukuze uyithwale ngcono, kufuneka ucinge ngokukhetha i-AC ukuya kwi-DC Adapter kwikhompyuter ekhaphukhaphu.
Ukhuseleko lokusingqongileyo kunye nokongiwa kwamandla kwiiadaptha zeDC
Isitshixo kwiiadaptha ze-ac dc kukuguqulwa okusebenzayo.Ukusebenza koguqulo oluphezulu lonikezelo lwamandla okutshintsha ekuqaleni kwakuyi-60% kuphela.Ngoku inokufezekisa ngaphezulu kwe-70% kunye ne-80% engcono.BTW, oku kukwalingana nexabiso.
Imowudi yokuhambelana yeeadaptha zeDC
Ngenxa yokuba iiadaptha ze-ac dc zingenalo ujongano olusemgangathweni oludityanisiweyo, izixhobo zangoku kwimarike kunokuthiwa zahlukile kwinqanaba lomnxibelelanisi.Wonke umntu kufuneka ahlolisise ngenyameko xa ekhetha.iiadaptha ze-ac dc zihlala zinexabiso elidadayo lamandla ombane osebenzayo kunye neeadaptha ze-ac dc ezinombane ofanayo.Iyahambelana nezicelo, ngaphandle nje kokuba ingagqithisi umda omkhulu wezixhobo zombane.
Ukuqina kweeadaptha zeDC
Ukuba ufumanisa ukuba iadaptha zonakele phambi kokuba uzisebenzise, ngoko ndiyakholelwa ukuba abantu abaninzi baya kuziva benxunguphele ngenxa yoku, kuba ukuqina kweeadaptha ze-ac dc kubaluleke kakhulu ngenxa yendalo esingqongileyo yesicelo.Ukongeza kwisicelo esiqhelekileyo sombane wonxibelelwano kunye neemveliso ze-elektroniki, abantu abaninzi bahlala bethatha iiadaptha ze-AC dc ngeenxa zonke, ukukhubeka akunakuphepheka, kwaye intambo iya kuhlala iqhekeza, eqinisekisa ukuba izinga lokuguga liyakhawuleza, ubomi benkonzo abunjalo. phezulu.
Ubume beeadaptha ze-ac dc
Phakathi kwabo, i-DC-DC converter isetyenziselwa ukuguqulwa kwamandla, eyona nxalenye engundoqo ye-ac dc adapters.Ukongeza, kukho iisekethe ezinjengokuqalisa, ukhuseleko olugqithileyo kunye nokhuseleko olugqithisileyo, kunye nokucoca ingxolo.Isekethe yesampula yokuphuma (R1R2) ibona utshintsho lwe-voltage ye-output kwaye ithelekisa kunye nereferensi.I-Voltage U, i-voltage yempazamo yothelekiso iyandiswa kwaye i-pulse wide modulation (PWM) yesekethe, kwaye emva koko umjikelo womsebenzi wesixhobo samandla ulawulwa yisekethe yokuqhuba, ukuze kufezekiswe injongo yokulungelelanisa umbane wemveliso.
Abaguquleli be-DC-DC baneentlobo ngeentlobo zeesekethe, ezidla ngokusetyenziswa ngabaguquli be-PWM abasebenzisa i-wave wave i-square wave kunye nabaguquli be-resonant abasebenzisa i-wave wave i-quasi-sine wave.
Kuluhlu olulawulwa ngumbane olulawulweyo, iimpawu zokuphendula ezidlulayo zesiphumo kwigalelo zimiselwa ikakhulu ziimpawu zokuphindaphinda kwetyhubhu yokupasa.Nangona kunjalo, kwi-quasi-sine wave resonant converter, kwi-switching elawulwayo yonikezelo lwamandla, utshintsho olufutshane lwegalelo lubonakaliswa ngakumbi ekupheleni kwemveliso.Ngelixa unyusa i-frequency switching, ingxaki yokuphendula okwethutyana yeeadaptha ze-ac dc nayo inokuphuculwa ngenxa yeempawu eziphuculweyo ze-frequency amplifier.Ukuphendula okwethutyana kotshintsho lomthwalo kumiselwa ikakhulu ziimpawu zesihluzi seLC ekupheleni kwemveliso, ngoko ke iimpawu zokuphendula okwethutyana zinokuphuculwa ngokunyusa isantya sokutshintsha kunye nokunciphisa imveliso yeLC yesihluzo semveliso.
