T: 5. Ta yaya masu ƙarfin lantarki na YMIN masu haɗakar ruwa suke tabbatar da aminci na dogon lokaci tare da tsawon rai sama da awanni 4000 a zafin jiki na 135°C?
A: Masu ƙarfin YMIN suna amfani da kayan polymer tare da juriya mai zafi, cikakken gwajin CCD, da kuma gwajin tsufa mai sauri (135°C yayi daidai da kimanin awanni 30,000 a 105°C) don tabbatar da aiki mai dorewa a cikin yanayin zafi mai yawa kamar sassan injin.
T:6. Menene kewayon bambancin ESR na capacitors masu ƙarfi-ruwa masu haɗin YMIN bayan sake haɗa su? Ta yaya ake sarrafa karkatarwa?
A: Bambancin ESR da aka auna na capacitors na YMIN shine ≤0.002Ω (misali, 0.0078Ω → 0.009Ω). Wannan saboda tsarin haɗakar ruwa mai ƙarfi yana hana rushewar electrolyte mai zafi, kuma tsarin ɗinki da aka haɗa yana tabbatar da daidaiton hulɗar lantarki.
T:7. Ta yaya ya kamata a zaɓi capacitors don rage yawan amfani da wutar lantarki a cikin da'irar matattarar shigarwar OBC?
A: Ana fifita samfuran YMIN masu ƙarancin ESR (misali, VHU_35V_270μF, ESR ≤8mΩ) don rage asarar matakin shigarwa. A lokaci guda, kwararar wutar lantarki ya kamata ta kasance ≤20μA don guje wa ƙaruwar amfani da wutar lantarki mai jiran aiki.
T:8. Menene fa'idodin capacitors na YMIN masu yawan ƙarfin capacitance (misali, VHT_25V_470μF) a matakin daidaita ƙarfin fitarwa na DCDC?
A: Babban ƙarfin aiki yana rage ƙarfin fitar da wutar lantarki mai ƙarfi kuma yana rage buƙatar tacewa daga baya. Tsarin da aka tsara (10×10.5mm) yana rage alamun PCB kuma yana rage ƙarin asara da ke faruwa sakamakon inductance na parasite.
T: 9. Shin sigogin capacitor na YMIN za su yi kasa kuma su shafi amfani da wutar lantarki a ƙarƙashin yanayin girgizar mota?
A: Na'urorin YMIN suna amfani da ƙarfafa tsarin (kamar ƙirar lantarki mai roba ta ciki) don tsayayya da girgiza. Gwaji ya nuna cewa canjin ESR da kwararar wutar lantarki bayan girgiza ba su wuce 1% ba, yana hana lalacewar aiki saboda matsin lamba na injiniya.
T: 10. Menene buƙatun tsari ga capacitors na YMIN yayin aikin sake haɗa soldering na 260°C?
A: Ana ba da shawarar cewa na'urorin capacitor su kasance nesa da ≥5mm daga abubuwan da ke samar da zafi (kamar MOSFETs) don guje wa zafi mai yawa a wurare daban-daban. Ana amfani da ƙirar kushin solder mai daidaiton zafi don rage damuwa a lokacin hawa.
T: 11. Shin capacitors masu ƙarfi da ruwa masu haɗaka na YMIN sun fi tsada fiye da capacitors na lantarki na gargajiya?
A: Na'urorin YMIN suna ba da tsawon rai (135°C/4000h) da ƙarancin amfani da wutar lantarki (yana adana farashin tsarin sanyaya), yana rage farashin zagayowar rayuwar na'urar gaba ɗaya da sama da 10%.
T:12. Shin YMIN zai iya samar da sigogi na musamman (kamar ƙananan ESR)?
A: Eh. Za mu iya daidaita tsarin lantarki bisa ga mitar sauyawar abokin ciniki (misali, 100kHz-500kHz) don ƙara rage ESR zuwa 5mΩ, don biyan buƙatun OBC masu inganci sosai.
T:13. Shin na'urorin haɗin gwiwa na YMIN masu ƙarfi da ruwa suna tallafawa dandamalin ƙarfin lantarki mai ƙarfi na 800V? Waɗanne samfura ne aka ba da shawarar?
A: Eh. Jerin VHT yana da ƙarfin juriya mafi girma na 450V (misali, VHT_450V_100μF) da kuma kwararar iska ta ≤35μA. An yi amfani da shi a cikin na'urorin DC-DC don motocin 800V da yawa.
T:14. Ta yaya masu haɗakar solid-liquid hybrid na YMIN ke inganta ƙarfin lantarki a cikin da'irori na PFC?
A: Ƙarancin ESR yana rage asarar ripple mai yawan gaske, yayin da ƙarancin ƙimar DF (≤1.5%) yana hana asarar dielectric, yana haɓaka ingancin matakin PFC zuwa ≥98.5%.
T:15. Shin YMIN tana ba da zane-zanen tunani? Ta yaya zan iya samun su?
A: Ana samun ɗakin karatu na ƙirar yanayin wutar lantarki na OBC/DCDC (gami da samfuran kwaikwayo da jagororin shimfidar PCB) a gidan yanar gizon mu na hukuma. Yi rijistar asusun injiniya don saukar da shi.
