I-DC (Direct Current) Guqula ibe yi-DC Transformer
Isiguquli se-DC/DC siyingxenye noma idivayisi eguqula i-DC (yamanje eqondile) ibe yi-DC, iqondise ngokukhethekile engxenyeni esebenzisa i-DC ukuze iguqule isuka kwelinye izinga likagesi iye kwelinye izinga likagesi.I-DC/DC ihlukaniswe yaba izigaba ezimbili ezisekelwe ekuguquleni izinga likagesi: I-transformer eyenza i-voltage ephansi kune-voltage yokuqala ibizwa ngokuthi "i-step-down transformer";I-transformer eyenza i-voltage ephakeme kune-voltage yokuqala ibizwa ngokuthi "i-boost transformer".Futhi ingahlukaniswa ibe yiphakeli yamandla eyodwa kanye nokuphakelwa kwamandla okungahlukanisiwe ngokusekelwe ebudlelwaneni bokufaka/okukhiphayo.Isibonelo, isiguquli se-DC/DC esixhunywe kugesi wemoto we-DC siguqula i-high-voltage DC ibe i-low-voltage DC.Futhi izingxenye ze-elekthronikhi ezifana nama-IC zinamabanga ahlukene kagesi wokusebenza, ngakho-ke nazo zidinga ukuguqulelwa kuma-voltage ahambisanayo.
Ngokukhethekile, kubhekiselwa ekuguquleni okokufaka kwe-DC kuya ku-AC ngokusebenzisa isekethe ye-Self-oscillation, bese kuguqulelwa ku-DC okukhiphayo ngemva kokushintsha i-voltage nge-transformer, noma ukuguqula i-AC iye ekuphumeni kwamandla kagesi aphezulu kwe-DC ngokusebenzisa isekethe yokuphinda iphindwe kabili kagesi.
Izinzuzo ezinemininingwane ziboniswa ngezansi:
(1) Ukuvuza kwe-inductance kungalawulwa ngaphakathi kwe-1% -10% ye-inductance eyinhloko;
(2) I-Magnetic core inokuhlangana okuhle kwe-electromagnetic, isakhiwo esilula nokusebenza kahle kokukhiqiza okuphezulu;
(3) Imvamisa yokusebenza ephezulu, ukuminyana kwamandla aphezulu, imvamisa phakathi kwe-50kHz ~ 300kHz.
(4) Izici ezinhle kakhulu zokukhipha ukushisa, ezinendawo ephezulu kuya kumthamo wevolumu, isiteshi sokushisa esifushane kakhulu, esilungele ukushabalalisa ukushisa.
(5) Ukusebenza kahle okuphezulu, ukwakheka kukazibuthe okuyinhloko komumo okhethekile wejometri kunganciphisa ngempumelelo ukulahlekelwa okuyinhloko.
(6) Ukuphazamiseka kwemisebe ye-electromagnetic emincane.Ukulahlekelwa kwamandla aphansi, ukukhuphuka kwezinga lokushisa eliphansi, ukusebenza kahle okuphezulu.
1. Ine-saturation ephezulu yokungenisa kazibuthe;
2. Izinga lokushisa eliphezulu le-Curie, ukulahlekelwa kwensimbi ephansi kanye nokuphoqelela;
3. Ukushisa okuhle kokushisa, umsindo ophansi nokusebenza kahle okuphezulu;
4. Ingangeni manzi, ingangenwa amanzi, ingangenwa uthuli futhi ingadlidlizi;
5. Ukuminyana kwamandla aphezulu;
6. Ukunemba okuphezulu kokuvuza kwe-inductance;
7. Ukuthembeka okuphezulu, ukuzinza okuphezulu, ukungaguquguquki okuphezulu;
Ibhodi lamandla emoto neseva.
