Q: Pa nthawi yochaja galimoto yatsopano yamagetsi, dashboard kapena chinsalu chowongolera chapakati chimazimitsa kapena kuyambiranso kwakanthawi. Kodi chifukwa chake chingakhale chiyani?
Yankho: Izi mwina ndi chifukwa chakuti panthawi yochaja galimoto, batire yamagetsi imadula mphamvu kwakanthawi kuti iwonetse chitetezo. Pakadali pano, zida zamagetsi zotsika mphamvu za galimoto yonse (monga dashboard ndi infotainment system) zimadalira kwathunthu chosinthira cha DC-DC. Ngati capacitance pa DC-DC output sikokwanira kapena kusakhazikika, sizingathe kubwezeretsanso mphamvu pakapita nthawi pamene katunduyo akuwonjezeka mwadzidzidzi, zomwe zimapangitsa kuti mphamvu yotulutsa itsike kwakanthawi ndipo zimapangitsa kuti chinsalu chizizire. Ma capacitor a YMIN VHT/VHU series automotive-grade ali ndi capacitance yawo yolamulidwa mwamphamvu mkati mwa mulingo wapamwamba kwambiri wa makampani a 0~+20%, kuonetsetsa kuti capacitor iliyonse imatha kupereka mphamvu yokwanira komanso yokhazikika, makamaka kuthetsa mavuto otsika kwa magetsi omwe amayamba chifukwa cha capacitance yosakwanira kapena kufalikira kwakukulu.

Q: Kodi mungasankhe bwanji ma capacitor a circuit yotulutsira fyuluta ya DC-DC converter mu galimoto yatsopano yamagetsi kuti muwonetsetse kuti magetsi ali olimba?
A: Chinsinsi chosankha capacitor chili mu kukhazikika kwa capacitance yake ndi kulolerana kwa ripple current. Choyamba, capacitance yoyesedwa ya capacitor iyenera kukhala yayikulu mokwanira kuti isunge kukhazikika kwa voltage pansi pa katundu wosiyanasiyana. Chofunika kwambiri, mtengo weniweni wa capacitance uyenera kusiyana pang'ono ndi mtengo wamba. Ma capacitor a YMIN automotive-grade, kudzera mu kuwongolera kokhwima kwa njira, amawongolera molondola kupotoka kwa capacitance mkati mwa 0 ~ + 20% (bwino kuposa ± 20%) wamba wamakampani. Izi zikutanthauza kuti kukhazikika kwa mphamvu yotulutsa kumakhala kotsimikizika mosavuta panthawi yopanga ndi kuyesa, kupewa zoopsa zomwe zimachitika chifukwa cha malire otsika kwambiri a capacitance.

Q: Kusagwira bwino ntchito kwa ma capacitor osiyanasiyana kumapangitsa kuti pakhale kusinthasintha kwa mphamvu panthawi yoyesa fakitale ya DC-DC board. Kodi izi zingathetsedwe bwanji?
A: Iyi ndi vuto lachizolowezi lowongolera khalidwe la unyolo woperekera zinthu. Ma capacitor a YMIN amatsimikizira kusinthasintha kwakukulu m'magawo ofunikira, makamaka capacitance, ya zinthu zake mwa kuyambitsa kuzindikira 100% CCD ndi mayeso okhwima okalamba panthawi yonse yopanga (monga riveting, winding, impregnation, ndi assembly). Mwa kukhazikika kwa capacitance tolerance mkati mwa 0% mpaka +20%, magwiridwe antchito okhazikika a ma DCDC board anu m'magulu osiyanasiyana amatsimikizika, zomwe zimapangitsa kuti zokolola za fakitale ndi kudalirika kwa zinthu ziyende bwino.

Q: Nchifukwa chiyani kulondola kwa capacitor capacitance ndikofunikira kwambiri pakupanga ma DCDC circuit? Kodi palibe njira yosinthira mayankho?
A: Ngakhale kuti feedback loop ingasinthidwedi, liwiro lake loyankha ndi lochepa. Mukakumana ndi kusintha kwa katundu wa microsecond kapena millisecond, feedback loop singayankhe pakapita nthawi. Pachifukwa ichi, udindo wosunga kukhazikika kwa magetsi umagwera pa mphamvu ya "kutulutsa mwachangu" ya capacitor yotulutsa. Ngati capacitance yeniyeni ya capacitor ndi yotsika kuposa mtengo wopangidwira (monga capacitor ya 330μF yokhala ndi mtengo weniweni wa 270μF yokha), malo ake osungira mphamvu sadzakwanira kuthana ndi kufunikira kwamphamvu kwamagetsi nthawi yomweyo, zomwe zimapangitsa kuti magetsi agwe komanso kusakhazikika kwa dongosolo. YMIN Capacitors imatsimikizira capacitance yocheperako kuposa mtengo wamba, kupereka maziko olimba a hardware kuti muyankhe mwachangu kwambiri.

Q: Kodi pali ma capacitor a solid-state kapena hybrid omwe amalimbikitsidwa, omwe amafunikira capacitance yayikulu komanso kusinthasintha kwabwino, pama module a DC-DC m'magalimoto atsopano amphamvu apamwamba?
A: Tikukulimbikitsani ma capacitor a YMIN a VHT ndi VHU series polymer hybrid solid-state capacitors. Mndandanda uwu wapangidwira makamaka kugwiritsa ntchito zamagetsi zamagalimoto, osati kokha kupereka mphamvu zambiri kuti zikwaniritse zofunikira zazikulu, komanso, chofunika kwambiri, kulekerera mphamvu mkati mwa 0 ~ + 20%, kuonetsetsa kuti munthu aliyense ali ndi mphamvu zokwanira. Mwachitsanzo, mitundu ya VHT_35V_330μF ndi VHU_35V_270μF imagwiritsidwa ntchito kwambiri mu ma converter a DC-DC okhala ndi mphamvu zambiri m'magalimoto atsopano amphamvu, kuonetsetsa kuti mphamvu zotulutsa mphamvu zimakhala zoyera komanso zokhazikika komanso kukwaniritsa zofunikira zodalirika za mitundu yapamwamba.
Funso Lalikulu: Bodi yathu ya DC-DC imakumana ndi mphamvu yotulutsa madzi ambiri ikagwiritsidwanso ntchito, zomwe zimapangitsa kuti mphamvu yokhazikika isagwiritsidwe ntchito bwino. Kodi pali ma capacitor omwe amasunga mphamvu yotulutsa madzi yochepa akagwiritsidwa ntchito ndi solder yotentha kwambiri?

Q: Pambuyo pa SMT surface mount reflow soldering, mphamvu yogwiritsidwa ntchito nthawi zonse ya DC-DC power board imaposa muyezo. Kafukufuku wasonyeza kuti izi zimachitika chifukwa cha kuchuluka kwa capacitor leakage current. Kodi izi zingapewedwe bwanji?
Yankho: Ili ndi vuto lofala kwambiri m'makampani, chifukwa cha kuwonongeka pang'ono komwe kumachitika chifukwa cha dielectric yamkati mwa ma capacitor chifukwa cha kutentha kwambiri kwa kutentha kwa reflow soldering. YMIN Capacitors imathetsa vutoli kudzera mu njira ziwiri zazikulu: Choyamba, ma CCD amayikidwa munjira zazikulu monga riveting ndi winding panthawi yopanga kuti ayang'anire 100% kuti athetse zolakwika zoyambirira; chachiwiri, mayeso ambiri okhwima okalamba amachitika asanatumizidwe, kuchotsa 100% zinthu zomwe ma current current parameters ake amatha kuwonongeka pambuyo pa kutentha. Izi zimatsimikizira kuti ma capacitor omwe amatumizidwa ku fakitale yanu, pambuyo pa reflow soldering, akadali ndi leak current yotsika kwambiri kuposa zofunikira zonse, kutsimikizira kuti kugwiritsa ntchito mphamvu zonse zoyimirira kumakwaniritsa miyezo.

Q: Kuti muchepetse kugwiritsa ntchito mphamvu yokhazikika ya ma module a DC-DC, ndi magawo ati omwe ayenera kuganiziridwa posankha ma capacitor?
A: Kupatula capacitance ndi ESR, leakage current ndi gawo lofunika kwambiri, makamaka pa ntchito zomwe zimafuna miyezo yokhazikika ya mphamvu zochepa. Muyenera kusamala osati kokha pa mtengo woyamba wa leakage current pa datasheet ya capacitor, komanso chofunika kwambiri, pa momwe leakage current imagwirira ntchito mutatha kuwona kutentha kwakukulu kwa reflow soldering. Miyezo yowunikira mafakitale a YMIN capacitors imaphatikizapo kuwongolera mwamphamvu mbali iyi, kuonetsetsa kuti chinthucho chimasunga leakage current yotsika kwambiri mutatha soldering, motero kukuthandizani kuchepetsa kugwiritsa ntchito mphamvu yonse yosasinthasintha ya chipangizocho.

Q: Zinthu zathu zamagetsi zamagalimoto zimafunika kwambiri pamlingo wolephera (zolakwika pafupifupi zero). Ndi njira ziti zowongolera khalidwe zomwe ma capacitor anu amagwiritsa ntchito kuti athandizire izi?
A: YMIN Capacitors imagwiritsa ntchito njira yowongolera khalidwe yomwe imayang'ana "zopanda vuto lililonse". Makamaka, kuti tipewe kutayikira kwamphamvu kwa magetsi, tayika zida zowunikira zodziwikiratu za CCD m'njira zonse zofunika popanga, monga kuponya, kuzunguliza, ndi kusonkhanitsa, kuti tichite kuwunika 100% ndikuletsa zinthu zilizonse zomwe zawonongeka kuti zisalowe munjira yotsatira. Pomaliza, kudzera munjira zambiri zowunikira kuphatikiza kukalamba ndi kuyesa magawo, timatsimikiza kuti zinthu zilizonse zomwe zingawonongeke pambuyo pobwezeretsanso solder pamalo a kasitomala zachotsedwa pasadakhale.
