[Umhlahlandlela Wokukhetha] Ungabhalansisa Kanjani Amandla Kagesi Aphezulu kanye Nempilo ende kuma-OBC amancane? Ukuhlaziywa kwe-YMIN LKD High-Voltage Capacitors

[Umhlahlandlela Wokukhetha] Ungabhalansisa Kanjani Amandla Kagesi Aphezulu kanye Nempilo ende kuma-OBC amancane? Ukuhlaziywa kwe-YMIN LKD High-Voltage Capacitors

Isingeniso

Kumiklamo ye-800V OBC kanye ne-DC-DC, ukukhetha kwe-capacitor sekuyinto ebalulekile ethinta ukuminyana kwamandla, ukusebenza kahle, nokuthembeka. Ama-electrolytic capacitor e-aluminium endabuko, ngenxa yosayizi wawo omkhulu, ubude besikhathi sokuphila okufushane, kanye nezici ezingezinhle zamaza aphezulu, awakwazi ukuhlangabezana nalezi zidingo. Lesi sihloko sizohlaziya izinzuzo zokusebenza zochungechunge lwe-YMIN Electronics' LKD high-voltage aluminium electrolytic capacitor ngokuya nge-miniaturization, ukumelana okuphezulu kwamanje, nempilo ende, ihlinzeka onjiniyela umhlahlandlela wokukhetha.

I-OBC – YMIN Aluminium Electrolytic Capacitor LKD Solution

Ngokusabalala kwamadivayisi e-SiC nokwanda kwamaza okushintsha, ama-capacitor kumamojula we-OBC kufanele amelane nokunyuka kwamagagasi aphezulu kanye nezingcindezi ezishisayo. Ama-capacitor e-aluminium electrolytic evamile ajwayele ukushisa ngokweqile futhi anesikhathi esifushane sokuphila. Ukuthola amandla aphezulu, ukumelana ne-voltage ephezulu, i-ESR ephansi, nokuphila isikhathi eside ngosayizi ohlangene kuye kwaba iphuzu eliyinhloko lobuhlungu ekwakhiweni kwe-OBC.

- Imbangela Ukuhlaziywa Kobuchwepheshe -

Umsuka wenkinga usekukhawulweni kwezinto kanye nenqubo yama-capacitor endabuko:

Ama-electrolyte ajwayelekile aguquguquka kalula emazingeni okushisa aphezulu, okuholela ekufipheleni kwe-capacitance kanye nokwanda kwe-ESR;

Imiklamo yesakhiwo evamile ine-capacitance density ephansi, okwenza kube nzima ukulinganisa amandla aphezulu kanye namandla;

Ukwethenjwa kokufakwa uphawu okunganele kuholela ekuvuzeni ezindaweni zokudlidliza.

Amapharamitha angukhiye afana ne-capacitance density, ESR @ 100kHz, i-ripple current @ 105°C, kanye neminyaka yokuphila kunomthelela ngokuqondile empumelelweni yesistimu.

- Izixazululo ze-YMIN kanye Nezinzuzo Zenqubo -

Uchungechunge lwe-YMIN LKD lusebenzisa izinqubo ezimbalwa ezintsha:

1. I-foil ye-electrode ene-high-density: Inyusa amandla ngevolumu yeyunithi ngayinye, inciphisa ivolumu ngo-20% kuya ku-40% uma kuqhathaniswa nemikhiqizo efanayo;

2. I-electrolyte ephansi ye-impedance: Yehlisa ngokuphumelelayo i-ESR futhi ithuthukise ukubekezelelana kwe-ripple high-frequency;

3. Ukufakwa uphawu okuqinisiwe kanye nesakhiwo sokuvikela ukuqhuma: Kudlula ukuhlolwa kokumelana nokudlidliza kwe-10G, ukuqeda izingozi zokuvuza;

4. Idizayini ye-high-voltage redundancy: Ihlinzeka ngemajini eyanele kagesi, ilungele izinhlelo zokusebenza ezisekelweni ezingu-800V nangaphezulu.

Ukuqinisekiswa Kwedatha Okuthembekile & Izincomo Zokukhetha

Njengoba kubonakala, uchungechunge lwe-LKD ludlula kakhulu imikhiqizo evamile ngokuya ngosayizi, i-ESR, ukumelana ne-ripple, kanye nempilo yokuphila.

- Izimo Zohlelo Lokusebenza Namamodeli Anconyiwe - Uchungechunge lwe-LKD lufanele: I-OBC PFC yokuthuthukisa ukuhlunga kokuphuma kwesekethe; Ukwesekwa kwe-DC-Link kanye nokubhafa; kanye nokuhlunga kwe-DC-DC.

- Amamodeli Anconyiwe -

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

I-LKD 500V 330μF 25×50: Ifanele ukuhlunga okunamandla aphezulu kumasistimu angu-800V;

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

I-LKD 500V 220μF: Ifanele ukusetshenziswa ezinhlelweni ezibambezeleke kakhulu endaweni.

Isiphetho

Uchungechunge lwe-YMIN's LKD, ngokusebenzisa izinto ezintsha nezakhiwo, lusingatha ngempumelelo ukuthembeka nezimfuneko zikasayizi ohlangene wama-capacitor ku-high-voltage, high-frequency, kanye nezinhlelo zokusebenza ezishisa kakhulu. Isiphenduke i-capacitor yokuzikhethela kumaphrojekthi we-OBC ezinkampanini eziningi ezihamba phambili zezimoto. Sisekela izinhlelo zokusebenza zesampula nokusekelwa kobuchwepheshe, sisiza onjiniyela basebenzise amaphrojekthi ngokushesha.
