1. U: Ama-Yongming Capacitors athi ukumelana kwawo nokudlidliza kuthuthukile kusuka ku-5-10g kuya ku-10-30g. Yiziphi izimo zokuhlola ezithile ezibhekiselwa kuzo leli “g”? Ingabe ukudlidliza okungahleliwe noma ukudlidliza kwe-sinusoidal? Yiziphi izindinganiso zokuhlola?
A: Lapha, “g” ibhekisela ekusheshisweni kwamandla adonsela phansi, iyunithi yokusheshisa ekuhlolweni kokudlidliza. Ipharamitha yokumelana nokudlidliza engu-10-30g ngokuvamile isekelwe ekuhlolweni kokudlidliza kwe-sinusoidal, okulingisa ukucindezeleka kokudlidliza okwenziwa umkhiqizo ngesikhathi sokuthuthwa nokusetshenziswa. Izindinganiso zokuhlola zomkhiqizo zibhekisela ezinhlotsheni zezinga lomkhakha ezifana ne-IEC 60068-2-6 (izinga le-International Electrotechnical Commission) ukuqinisekisa ukuqina kwayo kwemishini ezindaweni ezinokudlidliza okuphezulu.
2. U: Ngaphandle kokumelana nokudlidliza, yiziphi izinzuzo ezithile ezinazo le capacitor yoketshezi uma kuqhathaniswa nama-capacitor ajwayelekile e-liquid chip kanye nama-capacitor e-solid-state anezincazelo ezifanayo ngokwe-ESR (Equivalent Series Resistance) kanye nekhono lamanje le-ripple?
A: Uma kuqhathaniswa nama-capacitor ajwayelekile oketshezi, lo mkhiqizo, ngokusebenzisa i-electrode foil elungiselelwe kanye nokwakheka kwe-electrolyte, ubonisa i-ESR ephansi kanye nomthamo we-ripple olinganiselwe ophezulu ebangeni lokushisa elibanzi elisukela ku--40°C kuya ku-+105°C/125°C. Lokhu kubalulekile ekuphatheni ama-current pulse amakhulu ezinhlelweni zokulawula ze-elekthronikhi. Uma kuqhathaniswa nama-capacitor e-solid-state, unikeza ukusebenza kahle kwezindleko ezingcono emazingeni okushisa aphezulu kanye nezilinganiso ze-voltage ephezulu, futhi ugwema izici ze-DC bias zama-capacitor e-solid-state, okuholela ekuqineni okukhulu kwe-capacitance ngokushintsha kwe-voltage.
3. U: Lingakanani izinga lokushisa lokusebenza lalo mkhiqizo? Ikakhulukazi ezindaweni eziphakeme kakhulu neziphansi lapho izindiza eziphakeme kakhulu zingase zibhekane khona, ukusebenza kwe-capacitor ekushiseni okuphansi (isb., i-ESR iyashintsha ku--40°C)?
A: Ububanzi bokushisa bokusebenza komkhiqizo ojwayelekile bungu--40°C kuya ku-+105°C, kanti amanye amamodeli afinyelela ku-+125°C. Ezindaweni eziphakeme kakhulu nezinokushisa okuphansi, sithuthukise ngokukhethekile ukwakheka kwe-electrolyte ukuqinisekisa ukuthi ukwanda kwe-ESR kuhlala kungaphakathi kobubanzi obulawulwayo emazingeni okushisa aphansi kakhulu angu--40°C, okuqinisekisa ukuzinza kohlelo ngesikhathi sokuqala kokubanda kanye nokusebenza kwezinga lokushisa eliphansi.
4. U: Iyini ngempela isakhiwo se-capacitor “yokufaka esikhundleni”? Isiza kanjani ekuthuthukiseni ukumelana nokudlidliza? Ingabe kufezwa nge-potting compound ekhethekile, isakhiwo se-base mechanical, noma ukwakheka kohlaka lwe-lead?
A: I-capacitor “yokufaka endaweni” ibhekisela kuphakheji ye-capacitor core efakwe ngokuphephile esisekelweni sensimbi noma se-resin, bese ifakwa endaweni (SMT) ngama-pads esisekelweni. Ukumelana nokudlidliza okuthuthukisiwe kuncike kakhulu ku: 1) isakhiwo sesisekelo esiqinile esasakaza ukucindezeleka kokudlidliza kusuka ku-PCB kuya esisekelweni sonke; 2) ukuqina okuqinile kwephakheji ye-core yangaphakathi ukuvimbela ukunyakaza kwe-electrode yangaphakathi; kanye no-3) i-potting compound esebenza kahle kakhulu ukuze iqhubeke nokubopha nokumunca amandla okudlidliza. Lo mklamo onezinhlangothi ezintathu ngokubambisana ufeza igxathu elikhulu ekumelaneni nokudlidliza.
5. U: Yiziphi izinselele ama-capacitor abhekana nazo kubashayeli bephampu yamanzi/iphampu kawoyela ezinhlelweni zokuphatha ukushisa kwezimoto (njengokushisa okuphezulu kanye nomsinga omkhulu we-ripple)? I-Yung-Ming ibhekana kanjani nalezi zinselele?
A: Ama-capacitor kuma-driver e-water pump/oil pump ngokuvamile asetshenziselwa ukuhlunga nokufaka i-buffer ku-inverter output, ebhekene ne-ripple currents enkulu ekhiqizwa ukushintshashintsha kwemvamisa ephezulu, amazinga okushisa aphezulu enjini, kanye nokudlidliza kwenjini uqobo. Imikhiqizo yethu, enekhono layo eliphezulu le-ripple current, izinga lokushisa eliphezulu elingu-105°C/125°C, kanye nokumelana nokushaqeka okungu-10-30g, ingasebenza kahle ezindaweni ezinzima kangaka, iqinisekisa ukunemba nokuthembeka kokulawulwa kwemoto.
6: U: Ezinhlelweni ezibalulekile zokuphepha njenge-Electric Power Steering (EPS), yiziphi izindlela zokwehluleka kwama-capacitor? I-Yongming ikwandisa kanjani ukugwema ukwehluleka okubulalayo njengezifunda ezimfushane kanye nezifunda ezivulekile?
A: Ku-EPS, ukwehluleka kwe-capacitor (ikakhulukazi amasekethe amafushane) kungaholela ekukhubazekeni kwesistimu. Sithuthukisa ukuthembeka ngalezi zindlela ezilandelayo: 1) Ukusebenzisa izinto zokusetshenziswa ezihlanzekile kakhulu kanye nokulawula inqubo okuqinile ukunciphisa ukungcola kwangaphakathi; 2) Umklamo wevalvu engaqhumi (yize iwuhlobo lokufaka phezulu, inendlela yokukhulula ingcindezi esakhiweni sayo); 3) Ugesi wamandla angu-100% futhi imelana nokuhlolwa kwamandla kagesi ukuze kuqedwe ukwehluleka kwasekuqaleni. Ngaphezu kwalokho, ukumelana kwayo okuhle kakhulu kokushaqeka kuvimbela ngqo ukuqhekeka kwangaphakathi (amasekethe avulekile) noma amasekethe amafushane abangelwa ukudlidliza.
7: U: Ohlelweni lokulawula izindiza zezindiza ezisezingeni eliphansi, uyini umsebenzi oyinhloko wama-capacitor? Ingabe asetshenziselwa ukuhlunga amandla, ukugcina amandla, noma ukuxhumanisa isignali?
A: Isetshenziswa kakhulu kumasekethe okuphakelwa kwamandla amakhompyutha okulawula izindiza kanye nabashayeli bezimoto ze-servo, isebenza njengomlawuli we-voltage, isihlungi, kanye nomhlinzeki wamanje wokushaya kwenhliziyo okusheshayo. Izinhlelo zokulawula izindiza zinezidingo eziphakeme kakhulu zokuhlanzeka kwe-voltage kanye nokuphendula okusheshayo; ukusebenza okuzinzile kwe-capacitor kubalulekile ekuqinisekiseni idatha yenzwa enembile kanye nokuphendula okusheshayo kwe-servo.
8: U: I-spectrum yokudlidliza ebangelwa izinguquko zokuhamba komoya ezitholwa yizindiza iyinkimbinkimbi. Ingabe lo mkhiqizo ulungiselelwe ukudlidliza ebangeni elithile lemvamisa (isb., 50Hz-2000Hz)?
A: Yebo, ukuhlolwa kwethu kokudlidliza kuhlanganisa ububanzi obujwayelekile bemvamisa ebanzi (isb., 10Hz kuya ku-2000Hz), ngokunaka kakhulu amabhendi emvamisa ephakathi kuya phezulu ahlotshaniswa nemithombo evamile yokudlidliza kwezindiza (isb., ama-motor, ama-propeller). Ngokuklanywa kwesakhiwo, imvamisa yayo ezwakalayo igwema la mabhendi emvamisa abalulekile, ngaleyo ndlela igcine ukusebenza ngaphansi kwezimo eziyinkimbinkimbi zokudlidliza.
9: U: Izindiza eziphansi zizwela kakhulu isisindo. Le capacitor ifinyelela kanjani ukumelana nokudlidliza okuphezulu ngenkathi ilawula isisindo nosayizi wayo? Ingabe kukhona umklamo olula?
A: Silinganisela ukumelana nokudlidliza kanye ne-miniaturization ngesikhathi senqubo yokuklama. Ngokusebenzisa i-foil ye-electrode enamandla aphezulu ukunciphisa ivolumu yephakheji eyinhloko ukuze kube nomthamo ofanayo, nangokwenza ngcono inani lezinto eziyisisekelo kanye nezinto zokufaka, ngenkathi kuhlangatshezwana nesilinganiso sokumelana nokushaqeka esingu-10-30g, ivolumu kanye nesisindo sayo kuhlala kusezingeni elifanayo nemikhiqizo evamile enezincazelo ezifanayo, kuhlangatshezwana nezidingo ezilula zezindiza.
10Q: Uma kuqhathaniswa nama-capacitor aqinile, ama-capacitor aketshezi ngokuvamile anesikhathi sokuphila esilinganiselwe (ukoma kwe-electrolyte). I-Yung-Ming iyiqeda kanjani le nkinga?
A: Sandisa isikhathi sokuphila ngokusebenzisa ubuchwepheshe obubili obubalulekile: 1) sisebenzisa i-electrolyte ehlanganisiwe ene-voltage ephezulu ye-flash kanye nomfutho ophansi womusi ukuze sinciphise ukulahlekelwa ukuhwamuka emazingeni okushisa aphezulu; 2) sisebenzisa isivikelo senjoloba sokuvala esisebenza kahle kakhulu ukuze sinciphise kakhulu ukugeleza kwe-electrolyte. Lokhu kwandisa kakhulu isikhathi sokuphila kwama-capacitor ethu oketshezi emazingeni okushisa aphezulu.
