Intshayelelo

Kuyilo lwe-800V OBC kunye ne-DC-DC, ukhetho lwe-capacitor lube yinto ephambili echaphazela ukuxinana kwamandla, ukusebenza kakuhle, kunye nokuthembeka. Ii-capacitors ze-aluminiyam ze-aluminiyam ze-electrolytic, ngenxa yobukhulu bazo obukhulu, ubomi obufutshane, kunye neempawu ezisezantsi ze-frequency, azikwazi ukuhlangabezana nezi mfuno. Eli nqaku liza kuhlalutya iingenelo zokusebenza ze-YMIN Electronics 'LKD series high-voltage aluminiyam electrolytic capacitors ngokwemiqathango ye-miniaturization, ukuxhathisa okuphezulu kwangoku, kunye nobomi obude, ukubonelela ngeenjineli ngesikhokelo sokukhetha.

OBC - YMIN Aluminium Electrolytic Capacitor LKD Solution

Ngokuxhaphaka kwezixhobo ze-SiC kunye nokunyuka kwee-frequencies zokutshintsha, ii-capacitors kwiimodyuli ze-OBC kufuneka zimelane nemisinga ephezulu ye-ripple kunye noxinzelelo lwe-thermal. Ii-capacitors ze-aluminiyam eziqhelekileyo ze-aluminiyam ziyakwazi ukutshisa kakhulu kwaye ziphila ubomi obufutshane. Ukufezekisa i-capacitance ephezulu, ukuchasana nombane ophezulu, i-ESR ephantsi, kunye nobomi obude kwi-compact size ibe yintlungu engundoqo kwi-OBC design.

- Uhlalutyo lobuGcisa lweMbangela enguMbangela -

Oyena nobangela wengxaki ulele kwizinto kunye nenkqubo yokunciphisa i-capacitors yendabuko:

I-electrolyte eqhelekileyo iguquguquka ngokulula kumaqondo okushisa aphezulu, okukhokelela kwi-capacitance fading kunye nokunyuka kwe-ESR;

Uyilo oluqhelekileyo lwesakhiwo lunoxinano oluphantsi lwe-capacitance, okwenza kube nzima ukulinganisa amandla ombane aphezulu kunye ne-capacitance;

Ukuthembeka kokutywina okungonelanga kukhokelela ekuvuzeni kokusingqongileyo kokungcangcazela.

Iiparamitha eziphambili ezifana nokuxinana kwe-capacitance, ESR @ 100kHz, i-ripple current current @ 105 ° C, kunye nexesha lokuphila lichaphazela ngqo impumelelo yenkqubo.

-Izisombululo ze-YMIN kunye neNkqubo eluncedo -

Uthotho lwe-YMIN LKD lusebenzisa iinkqubo ezininzi ezintsha:

1. I-high-density electrode foil: Ukwandisa i-capacitance ngeyunithi yomthamo, ukunciphisa umthamo nge-20% ukuya kwi-40% xa kuthelekiswa neemveliso ezifanayo;

2. I-electrolyte ephantsi kwe-impedance: Ukunciphisa ngokufanelekileyo i-ESR kunye nokuphucula ukunyamezela kwe-ripple-frequency ripple;

3. Ukutywinwa okuqinisiweyo kunye nesakhiwo sobungqina bokuqhuma: Idlula uvavanyo lwe-10G lokuxhathisa i-vibration, ukuphelisa umngcipheko wokuvuza;

4. Uyilo lwe-high-voltage redundancy: Ibonelela ngomlinganiselo omkhulu wombane, olungele ukusetyenziswa kwiiplatifti ze-800V nangaphezulu.

Ukuthembeka kweDatha yoQinisekiso kunye neeNgcebiso zokuKhetha

Njengoko kunokubonwa, uchungechunge lwe-LKD lugqithisa kakhulu iimveliso eziqhelekileyo ngokobungakanani, i-ESR, ukuxhathisa i-ripple, kunye nobomi.

- Iimeko zeSicelo kunye neeModeli ezicetyiswayo - Uluhlu lwe-LKD lufanelekile: I-OBC PFC yokunyusa i-circuit output filtering; Inkxaso ye-DC-Link kunye ne-buffering; kunye nokucoca iDC-DC.

- Iimodeli ezicetyiswayo -

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

I-LKD 500V 330μF 25 × 50: Ifanelekile ukucoca umthamo ophezulu kwiinkqubo ze-800V;

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

I-LKD 500V 220μF: Ifanelekile ukuba isetyenziswe kwizicelo ezinobunzima kakhulu kwisithuba.

Ukuqukumbela

Uchungechunge lwe-LKD lwe-YMIN, ngokusebenzisa izinto ezintsha kunye nezakhiwo, zijongene ngokuphumelelayo nokuthembeka kunye neemfuno zesayizi ezidibeneyo ze-capacitors kwi-high-voltage, i-high-frequency, kunye ne-high-temperature applications. Iye yaba yicapacitor yokuzikhethela kwiiprojekthi ze-OBC kwiinkampani ezininzi eziphambili zeemoto. Sixhasa izicelo zesampula kunye nenkxaso yobugcisa, ukunceda iinjineli ngokukhawuleza ukuphumeza iiprojekthi.
