DC (Toos ah hadda) U beddel beddelka DC
Transformer-ka DC/DC waa qayb ama qalab u beddela DC ( hadda toos ah) una beddela DC, gaar ahaan waxa loola jeedaa qayb ka faa'iidaysata DC si looga beddelo hal heer danab oo loo beddelo heer danab kale.DC/DC waxa loo qaybiyaa laba qaybood oo ku salaysan isbedelka heerka danab: Transformer-ka dhaliya koronto ka hoosaysa ta hore waxa loo yaqaan "Transformer";Transformer-ka dhaliya koronto ka sarraysa ta hore waxa loo yaqaan "boost transformer".Waxa kale oo loo qaybin karaa sahay koronto oo go'doonsan iyo koronto aan go'doon ahayn oo ku salaysan xidhiidhka wax-gelinta/soo-saarka.Tusaale ahaan, beddelaha DC/DC ee ku xidhan sahayda korantada DC ee baabuurka waxay u beddeshaa koronto-sarre DC ah oo u beddela DC-yar.Qaybaha elektiroonigga ah sida IC-yada waxay leeyihiin kala duwanaansho koronto oo shaqeynaya, sidaas darteed waxay sidoo kale u baahan yihiin in loo beddelo danab u dhigma.
Gaar ahaan, waxa ay tilmaamaysaa in wax-soo-saarka DC-ga loo beddelo AC iyada oo loo marayo wareegga is-oscillation-ka, ka dibna loo beddelo wax-soo-saarka DC ka dib marka la beddelo tamarta iyada oo loo marayo transformer, ama u beddelashada AC wax-soo-saarka koronto-sare ee DC iyada oo loo marayo wareegga laba-laabashada danab.
Faa'iidooyinka faahfaahsan ayaa lagu muujiyay hoos:
(1) Inductance dareere ah waxaa lagu xakameyn karaa 1% -10% ee inductance ugu weyn;
(2) Xuddunta magnetic waxay leedahay isku-xidhka elektromagnetic-ka wanaagsan, qaab-dhismeedka fudud iyo wax-soo-saarka sare;
(3) Inta jeer ee shaqada, cufnaanta awoodda sare, inta jeer ee u dhaxaysa 50kHz ~ 300kHz.
(4) Sifooyin kuleyl aad u fiican, oo leh meel sare oo dusha sare ah ilaa saamiga mugga, kanaalka kulaylka oo aad u gaaban, oo ku habboon kuleylka kuleylka.
(5) Waxtarka sare, qaab-dhismeedka asaasiga ah ee magnetic ee qaabka gaarka ah ee joomatari wuxuu si wax ku ool ah u yareeyn karaa khasaaraha asaasiga ah.
(6) Faragelin yar oo shucaaca korantada.Luminta tamarta hoose, heerkulka hooseeya, waxtarka sare.
1. Leh saturation magnetic induction sare;
2. Heerkulka Curie oo sarreeya, luminta birta oo yar iyo qasab;
3. Kulaylka wanaagsan ee kuleylka, qaylada hoose iyo waxtarka sare;
4. Biyo-celinta, qoyaan-celinta, boodhka-celinta iyo gariir-celinta;
5. Cufnaanta awoodda sare;
6. Saxnaanta sare ee dheecaanka inductance;
7. Isku halaynta sare, xasilloonida sare, joogteynta sare;
Boodhka korontada ee gaadiidka iyo serverka.
