I-DC (Ngqo ngoku) Guqula kwi-DC Transformer
I-DC/DC transformer licandelo okanye isixhobo esiguqula i-DC (ngokuthe ngqo) ukuya kwi-DC, ibhekisa ngokukodwa kwicandelo elisebenzisa i-DC ukuguqula ukusuka kwinqanaba lombane ukuya kwelinye inqanaba lombane.I-DC/DC yohlulwe yangamacandelo amabini asekelwe kuguquko lwenqanaba lombane: I-transformer eyenza i-voltage engaphantsi kwe-voltage yokuqala ibizwa ngokuba yi-"step-down transformer";I-transformer eyenza i-voltage ephezulu kune-voltage yokuqala ibizwa ngokuba yi-"boost transformer".Kwaye inokwahlulwa ibe yinkxaso yombane ezimeleyo kunye nonikezelo lwamandla olungabodwa olusekwe kubudlelwane begalelo/isiphumo.Umzekelo, i-DC/DC converter eqhagamshelwe kwi-DC yesithuthi sombane iguqula i-high-voltage DC ibe yi-low-voltage DC.Kwaye amacandelo e-elektroniki anje ngee-IC aneendlela ezahlukeneyo zombane osebenzayo, ngoko ke kufuneka aguqulelwe kumbane ohambelanayo.
Ngokukodwa, ibhekisa ekuguquleni igalelo le-DC libe yi-AC ngesekethe ye-Self-oscillation, emva koko iguqulelwe kwi-DC output emva kokutshintsha i-voltage nge-transformer, okanye ukuguqula i-AC ibe yi-high-voltage output ye-DC ngokusebenzisa i-voltage ephinda-phinda kabini isekethe yokubuyisela.
Iinzuzo ezineenkcukacha ziboniswe apha ngezantsi:
(1) Ukuvuza okuvuzayo kunokulawulwa ngaphakathi kwe-1% -10% ye-inductance engundoqo;
(2) Undoqo weMagnetic unonxibelelwano olululo lwe-electromagnetic, ulwakhiwo olulula kunye nokusebenza kakuhle kwemveliso;
(3) I-frequency ephezulu yokusebenza, ukuxinana kwamandla aphezulu, ukuphindaphinda phakathi kwe-50kHz ~ 300kHz.
(4) Iimpawu ezigqwesileyo zokutshatyalaliswa kobushushu, kunye nommandla ophezulu ukuya kumlinganiselo wevolumu, umjelo omfutshane kakhulu wokushisa, olungele ukutshatyalaliswa kobushushu.
(5) Ukusebenza okuphezulu, ulwakhiwo olungundoqo lwamagnetic lobume bejometri ekhethekileyo lunokunciphisa ngokufanelekileyo ilahleko engundoqo.
(6) Ukuphazamiseka kwemitha ye-electromagnetic encinci.Ukulahlekelwa kwamandla aphantsi, ukunyuka kweqondo lokushisa eliphantsi, ukusebenza kakuhle okuphezulu.
1. Inokufakwa kwimagnethi yokugcwala okuphezulu;
2. Ubushushu obuphezulu beCurie, ilahleko yentsimbi ephantsi kunye nokunyanzeliswa;
3. Ukutshatyalaliswa kobushushu obuhle, ingxolo ephantsi kunye nokusebenza okuphezulu;
4. Ukungangeni kwamanzi, ukufuma, ukungenwa luthuli kunye nokungcangcazela;
5. Ukuxinana kwamandla aphezulu;
6. Ukuchaneka okuphezulu kokuvuza kwe-inductance;
7. Ukuthembeka okuphezulu, ukuzinza okuphezulu, ukuhambelana okuphezulu;
Ibhodi yemoto kunye neseva yamandla.
