Intshayelelo

Kwi-800V OBC kunye ne-DC-DC designs, ukukhethwa kwe-capacitor kube yinto ephambili echaphazela uxinano lwamandla, ukusebenza kakuhle, kunye nokuthembeka. Ii-capacitor ze-aluminium electrolytic zemveli, ngenxa yobukhulu bazo obukhulu, ubomi obufutshane, kunye neempawu ezingezizo ze-high-frequency, azikwazi ukuhlangabezana nezi mfuno. Eli nqaku liza kuhlalutya iingenelo zokusebenza kwee-capacitor ze-aluminium electrolytic ze-YMIN Electronics' LKD series high-voltage aluminium electrolytic ngokubhekiselele kwi-miniaturization, ukumelana nombane ophezulu, kunye nobomi obude, zibonelela iinjineli ngesikhokelo sokukhetha.

Isisombululo se-LKD se-OBC – YMIN Aluminium Electrolytic Capacitor

Ngenxa yokuxhaphaka kwezixhobo zeSiC kunye nokwanda kwamaza okutshintsha, ii-capacitors kwiimodyuli ze-OBC kufuneka zimelane nemisinga ephezulu ye-ripple kunye noxinzelelo lobushushu. Ii-capacitors ze-aluminium ze-electrolytic eziqhelekileyo zinobunzima bokushushu kakhulu kwaye zihlala ixesha elifutshane. Ukufikelela kwi-capacitance ephezulu, ukumelana ne-voltage ephezulu, i-ESR ephantsi, kunye nobomi obude kubukhulu obuncinci kube yeyona nto inzima kuyilo lwe-OBC.

- Uhlalutyo loBugcisa lweMpembelelo -

Unobangela oyintloko wale ngxaki ukwimida yezinto kunye neenkqubo zee-capacitors zemveli:

Ii-electrolyte eziqhelekileyo zitshintshatshintsha lula xa kushushu kakhulu, nto leyo ekhokelela ekuphelelweni kwamandla kunye nokwanda kwe-ESR;

Uyilo lwezakhiwo oluqhelekileyo lunoxinano oluphantsi lwe-capacitance, nto leyo eyenza kube nzima ukulinganisela i-voltage ephezulu kunye ne-capacitance;

Ukuthembeka kokutywina okunganelanga kukhokelela ekuvuzeni kwamanzi kwiindawo zokungcangcazela.

Iiparameter eziphambili ezifana noxinano lwe-capacitance, i-ESR @ 100kHz, i-ripple current elinganiswe kwi-105°C, kunye nobomi bexesha lokusebenzisa i-intanethi buchaphazela ngqo impumelelo yenkqubo.

- Izisombululo ze-YMIN kunye neeNzuzo zeNkqubo -

Uthotho lwe-YMIN LKD lusebenzisa iinkqubo ezininzi ezintsha:

1. Ifoyile ye-electrode enoxinano oluphezulu: Yonyusa umthamo ngeyunithi nganye, inciphisa umthamo nge-20% ukuya kwi-40% xa kuthelekiswa neemveliso ezifanayo;

2. I-electrolyte engasebenzi kakuhle: Inciphisa i-ESR kwaye iphucula ukunyamezelana kwamaza amaninzi;

3. Ulwakhiwo oluqinisiweyo lokutywina kunye nolungenakuqhuma: Ludlula uvavanyo lokumelana nokungcangcazela lwe-10G, lususa iingozi zokuvuza;

4. Uyilo lokuphinda-phinda amandla e-voltage ephezulu: Ibonelela nge-voltage margin eyaneleyo, efanelekileyo kwiiplatifomu ze-800V nangaphezulu.

Ukuqinisekiswa kwedatha yokuthembeka kunye neengcebiso zokukhetha

Njengoko kunokubonwa, uthotho lwe-LKD luphumelela kakhulu kwiimveliso zesiqhelo ngokobukhulu, i-ESR, ukumelana ne-ripple, kunye nobomi bokuphila.

- Iimeko zoSetyenziso kunye neeModeli eziCetyisiweyo – Uthotho lwe-LKD lufanelekile kwi: Ukucoca i-OBC PFC boost circuit output filtering; Inkxaso ye-DC-Link kunye ne-buffering; kunye nokucoca i-DC-DC.

- Iimodeli ezicetyiswayo -

I-LKD 700V 150μF 25×50: Ifanelekile kwiinkqubo ze-DC-Link ze-1200V;

I-LKD 500V 330μF 25×50: Ifanelekile ekuhluzweni okunamandla aphezulu kwiinkqubo ze-800V;

I-LKD 450V 330μF: Ibhalansisa ubungakanani kunye neemfuno zomthamo;

I-LKD 500V 220μF: Ifanelekile ukusetyenziswa kwiindawo ezixineneyo kakhulu.

Isiphelo

Uthotho lwe-YMIN's LKD, ngokusebenzisa izixhobo ezintsha kunye nezakhiwo, lujongana ngempumelelo neemfuno zokuthembeka kunye nobukhulu obuncinci bee-capacitors kwizicelo ze-high-voltage, high-frequency, kunye ne-high-temperature. Luye lwaba yi-capacitor ekhethwayo kwiiprojekthi ze-OBC kwiinkampani ezininzi eziphambili zeemoto. Sixhasa izicelo zeesampulu kunye nenkxaso yobugcisa, sinceda iinjineli ukuba ziqalise iiprojekthi ngokukhawuleza.
