[Ubuyobozi bwo Guhitamo] Nigute Wakoresha Ubushobozi bwo Kuringaniza Voltage Nyinshi no Kuramba mu Bice Bito bya OBC? Isesengura rya YMIN LKD High-Voltage Capacitors

Intangiriro

Mu miterere ya 800V OBC na DC-DC, guhitamo capacitor byabaye ikintu cy'ingenzi bigira ingaruka ku bucucike bw'ingufu, imikorere myiza, no kwizerwa. Capacitors gakondo za aluminium electrolytic, bitewe n'ingano yazo nini, igihe gito cyo kumara, ndetse n'imiterere mibi ya frequency yo hejuru, ntizishobora kuzuza ibi bisabwa. Iyi nkuru izasesengura ibyiza by'imikorere ya capacitors za aluminium electrolytic za YMIN Electronics za LKD series mu bijyanye no gukora capacitors ntoya, ubushobozi bwo guhangana n'umuriro mwinshi, no kuramba igihe kirekire, ibaha abahanga ubuyobozi bwo guhitamo.

OBC – YMIN Aluminium Electrolytic Capacitor LKD Igisubizo

Bitewe n’ubwinshi bw’ibikoresho bya SiC no kwiyongera kw’imivuduko yo guhinduranya, capacitors muri module za OBC zigomba kwihanganira imigezi myinshi ya ripple n’ubushyuhe. Capacitors zisanzwe za aluminium electrolytic zikunze gushyuha cyane kandi zimara igihe gito. Kugera ku bushobozi bwinshi, ubudahangarwa bw’amashanyarazi menshi, ESR nke, no kuramba mu bunini buto byabaye ikibazo gikomeye mu gishushanyo cya OBC.

- Isesengura rya tekiniki ry'impamvu nyamukuru -

Impamvu nyamukuru y'ikibazo iri mu nzitizi z'ibikoresho n'imikorere ya capacitors gakondo:

Electrolyte zisanzwe zihinduka byoroshye iyo ubushyuhe bwinshi bukabije, bigatuma ubushobozi bwo gukora bugabanuka kandi ESR yiyongera;

Imiterere isanzwe y'inyubako ifite ubushobozi buke bwo gukoresha, bigatuma bigorana kuringaniza ingufu nyinshi z'amashanyarazi n'ubushobozi bwo gukoresha ingufu;

Kudakora neza kw'ifungwa bituma habaho gusohoka kw'amazi mu bice bihindagurika.

Ibipimo by'ingenzi nka capacitance density, ESR @ 100kHz, rated ripple current @ 105°C, hamwe n'ubuzima bw'igihe bizagira ingaruka zitaziguye ku ntsinzi ya sisitemu.

- Ibisubizo bya YMIN n'Ibyiza by'Imikorere -

Uruhererekane rwa YMIN LKD rukoresha inzira nyinshi zigezweho:

1. Agapapuro k'amashanyarazi gafite ubucucike bwinshi: Kongera ubushobozi bwo gukoresha kuri buri gice cy'ingano, bigabanya ingano ho 20% kugeza kuri 40% ugereranije n'ibindi bisa;

2. Electrolyte ifite impedance nke: Igabanya neza ESR kandi ikongera ubushobozi bwo kwihanganira amajwi menshi;

3. Imiterere yo gufunga no kwirinda guturika: Ipima 10G irwanya guhindagurika, ikavanaho ibyago byo gusohoka kw'amazi;

4. Igishushanyo mbonera cy’ingufu nyinshi: Gitanga ingano ihagije y’amashanyarazi, ikwiriye gukoreshwa ku mbuga za 800V no hejuru yayo.

Ibyifuzo byo kugenzura amakuru no guhitamo neza

Nkuko bigaragara, uruhererekane rwa LKD rurusha cyane ibicuruzwa bisanzwe mu bunini, ESR, kurwanya amagufwa, ndetse n'igihe rumaze.

- Imiterere y'Ikoreshwa n'Ibyitegererezo Byifuzwa – Uruhererekane rwa LKD rukwiriye: Gushungura umusaruro wa OBC PFC; Gushyigikira no gufunga DC-Link; no Gushungura DC-DC.

- Moderi zisabwa -

LKD 700V 150μF 25×50: Ikwiriye sisitemu za DC-Link za 1200V;

LKD 500V 330μF 25×50: Ikwiriye gukoreshwa mu gushungura bifite ubushobozi bwo hejuru muri sisitemu za 800V;

LKD 450V 330μF: Ipima ingano n'ubushobozi bw'ibikoresho;

LKD 500V 220μF: Ikwiriye gukoreshwa mu bintu bito cyane.

Umwanzuro

Uruhererekane rwa YMIN rwa LKD, binyuze mu bikoresho n'imiterere bishya, rukemura neza ibisabwa mu buryo bwizewe no mu bunini buto bya capacitors mu mikoreshereze ya voltage nyinshi, frequency nyinshi, n'ubushyuhe bwinshi. Rwabaye capacitor ikundwa cyane mu mishinga ya OBC mu bigo byinshi bikomeye by'imodoka. Dushyigikira ingero z'ikoreshwa n'ubufasha bwa tekiniki, dufasha injeniyeri gushyira mu bikorwa imishinga vuba.
