[Umhlahlandlela Wokukhetha] Ungalinganisa Kanjani I-High Voltage kanye Nempilo Ende Kuma-OBC Amancane? Ukuhlaziywa Kwama-Capacitors Aphezulu E-YMIN LKD

[Umhlahlandlela Wokukhetha] Ungalinganisa Kanjani I-High Voltage kanye Nempilo Ende Kuma-OBC Amancane? Ukuhlaziywa Kwama-Capacitors Aphezulu E-YMIN LKD

Isingeniso

Kumiklamo engu-800V OBC kanye ne-DC-DC, ukukhetha i-capacitor kube yinto ebalulekile ethinta ukuminyana kwamandla, ukusebenza kahle, kanye nokuthembeka. Ama-capacitor e-aluminium electrolytic endabuko, ngenxa yobukhulu bawo obukhulu, isikhathi esifushane sokuphila, kanye nezici ezingezinhle zemvamisa ephezulu, awakwazi ukuhlangabezana nalezi zidingo. Lesi sihloko sizohlaziya izinzuzo zokusebenza kwama-capacitor e-aluminium electrolytic e-YMIN Electronics' LKD series high-voltage aluminium electrolytic ngokuya nge-miniaturization, ukumelana kwamanje kwe-ripple ephezulu, kanye nesikhathi eside sokuphila, sinikeze onjiniyela umhlahlandlela wokukhetha.

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

Njengoba amadivayisi e-SiC evame kakhulu kanye nokwanda kwama-switching frequency, ama-capacitor kumamojula e-OBC kumele amelane nemisinga ephezulu ye-ripple kanye nokucindezeleka kokushisa. Ama-capacitor e-aluminium electrolytic avamile athambekele ekushiseni ngokweqile futhi aphila isikhathi esifushane. Ukufinyelela amandla aphezulu, ukumelana namandla aphezulu, i-ESR ephansi, kanye nokuphila isikhathi eside ngobukhulu obuncane sekuyinto ebuhlungu kakhulu ekwakhiweni kwe-OBC.

- Ukuhlaziywa Kobuchwepheshe Bembangela Eyinhloko -

Imbangela eyinhloko yale nkinga isekulinganiselweni kwezinto ezibonakalayo kanye nezinqubo zama-capacitor endabuko:

Ama-electrolyte avamile ashintshashintsha kalula emazingeni okushisa aphezulu, okuholela ekuncipheni kwamandla kanye nokwanda kwe-ESR;

Imiklamo yesakhiwo evamile inomthamo ophansi wokusebenza, okwenza kube nzima ukulinganisela i-voltage ephezulu kanye nomthamo;

Ukwethenjelwa kokuvala okunganele kuholela ekuvuza ezindaweni zokudlidliza.

Amapharamitha abalulekile njengobuningi be-capacitance, i-ESR @ 100kHz, i-ripple current elinganisiwe @ 105°C, kanye nokuphila kwesikhathi kuthinta ngqo impumelelo yesistimu.

- Izixazululo ze-YMIN kanye Nezinzuzo Zenqubo -

Uchungechunge lwe-YMIN LKD lusebenzisa izinqubo eziningana ezintsha:

1. I-foil ye-electrode enobukhulu obuphezulu: Yandisa amandla ngevolumu yeyunithi ngayinye, yehlisa ivolumu ngo-20% kuya ku-40% uma kuqhathaniswa nemikhiqizo efanayo;

2. I-electrolyte ephansi yokuvimbela: Yehlisa ngempumelelo i-ESR futhi ithuthukise ukubekezelelana kwama-ripple amaningi;

3. Ukuqina kokuvala kanye nesakhiwo esingavimbeli ukuqhuma: Kudlula ukuhlolwa kokumelana nokudlidliza okungu-10G, kususa izingozi zokuvuza;

4. Umklamo wokuphindaphinda kwamandla kagesi aphezulu: Uhlinzeka nge-voltage margin eyanele, efanele ukusetshenziswa kumapulatifomu angu-800V nangaphezulu.

Ukuqinisekiswa Kwedatha Nokukhethwa Kokuthembeka

Njengoba kungabonakala, uchungechunge lwe-LKD ludlula kakhulu imikhiqizo evamile ngokuya ngobukhulu, i-ESR, ukumelana nama-ripple, kanye nesikhathi sokuphila.

- Izimo Zokusebenza Namamodeli Anconyiwe – Uchungechunge lwe-LKD lufanelekela: Ukuhlunga kokukhipha kwesekethe yokukhulisa i-OBC PFC; Ukusekelwa kwe-DC-Link kanye nokubhafa; kanye nokuhlunga kwe-DC-DC.

- Amamodeli Anconyiwe -

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

I-LKD 500V 330μF 25×50: Ifanelekela ukuhlunga okunamandla aphezulu ezinhlelweni ze-800V;

I-LKD 450V 330μF: Ilinganisa usayizi nezidingo zomthamo;

I-LKD 500V 220μF: Ifanele ukusetshenziswa ezindaweni ezincishisiwe kakhulu.

Isiphetho

Uchungechunge lwe-YMIN lwe-LKD, ngokusebenzisa izinto ezintsha nezakhiwo, lubhekana ngempumelelo nezidingo zokuthembeka kanye nosayizi omncane wama-capacitor kuzinhlelo zokusebenza ze-voltage ephezulu, imvamisa ephezulu, kanye nokushisa okuphezulu. Sekuyi-capacitor ekhethwayo yamaphrojekthi e-OBC ezinkampanini eziningi zezimoto ezihamba phambili. Sisekela izinhlelo zokusebenza zesampula kanye nokusekelwa kobuchwepheshe, sisiza onjiniyela ukuthi baqalise amaphrojekthi ngokushesha.
