1. Q: I-Yongming Capacitors ithi ukumelana kwayo nokungcangcazela kuphucukile ukusuka kwi-5-10g ukuya kwi-10-30g. Zeziphi iimeko ezithile zovavanyo ezibhekisele kulo “g”? Ingaba kukungcangcazela okungacwangciswanga okanye kukungcangcazela kwe-sinusoidal? Zithini imigangatho yovavanyo?
A: Apha, igama elithi “g” libhekisa ekukhawulezisweni komxhuzulane, iyunithi yokukhawulezisa kuvavanyo lokungcangcazela. Ipharamitha yokumelana nokungcangcazela eyi-10-30g idla ngokusekwe kuvavanyo lokungcangcazela lwe-sinusoidal, olulinganisa uxinzelelo lokungcangcazela olufunyanwa yimveliso ngexesha lokuthuthwa nokusetyenziswa. Imigangatho yovavanyo lwemveliso ibhekisa kwiinkcukacha zomgangatho weshishini ezifana ne-IEC 60068-2-6 (umgangatho weKhomishini ye-Electrotechnical yeHlabathi) ukuqinisekisa ukomelela kwayo koomatshini kwiindawo ezinokungcangcazela okuphezulu.
2. Q: Ngaphandle kokumelana nokungcangcazela, zeziphi iingenelo ezithile ezinazo ezi capacitor yolwelo xa kuthelekiswa nee capacitors eziqhelekileyo ze-chip yolwelo kunye nee capacitors ze-solid-state ezineenkcazo ezifanayo ngokwe-ESR (Equivalent Series Resistance) kunye nokukwazi ukusebenza kwe-ripple current?
A: Xa kuthelekiswa nee-capacitors eziqhelekileyo zolwelo, le mveliso, ngokusebenzisa i-electrode foil elungiselelweyo kunye ne-electrolyte formulation, ibonisa i-ESR ephantsi kunye ne-ripple current ephezulu kuluhlu olubanzi lobushushu ukusuka kwi--40°C ukuya kwi-+105°C/125°C. Oku kubalulekile ekuphatheni ii-current pulses ezinkulu kwiinkqubo zolawulo lwe-elektroniki. Xa kuthelekiswa nee-capacitors ze-solid-state, inika ukusebenza ngcono kweendleko kumaqondo obushushu aphezulu kunye novavanyo lwe-voltage ephezulu, kwaye ithintela iimpawu ze-DC bias zee-capacitors ze-solid-state, nto leyo ekhokelela kwi-capacitance ezinzileyo ngakumbi ngotshintsho lwe-voltage.
3. Q: Ingakanani iqondo lobushushu lokusebenza kwale mveliso? Ingakumbi kwiindawo eziphakamileyo nezinobushushu obuphantsi ezinokubonwa ziintaka ezisezantsi, injani indlela esebenza ngayo i-capacitor kubushushu obuphantsi (umz., i-ESR itshintsha kwi -40°C)?
A: Uluhlu lobushushu bokusebenza kwemveliso eqhelekileyo luphakathi kwe -40°C ukuya kwi +105°C, kwaye ezinye iimodeli zifikelela kwi +125°C. Kwiindawo eziphakamileyo nezinobushushu obuphantsi, silungiselele ngokukodwa ukwakheka kwe-electrolyte ukuqinisekisa ukuba ukunyuka kwe-ESR kuhlala kukwinqanaba elilawulekayo kumaqondo obushushu aphantsi kakhulu angama -40°C, okuqinisekisa uzinzo lwenkqubo ngexesha lokuqala kokubanda kunye nokusebenza kobushushu obuphantsi.
4. Q: Yintoni kanye kanye isakhiwo se-capacitor "esifakelwa kwi-mount-mount"? Inceda njani ekuphuculeni ukumelana nokungcangcazela? Ingaba ifezekiswa ngokusebenzisa i-potting compound ekhethekileyo, isakhiwo se-base mechanical, okanye uyilo lwesakhelo se-lead?
A: I-capacitor "yokukhwelisa" ibhekisa kwiphakheji ye-capacitor core efakwe ngokukhuselekileyo kwisiseko sesinyithi okanye se-resin, ize ibekwe phezu komhlaba (SMT) ngee-pads kwisiseko. Ukumelana nokungcangcazela okuphuculweyo kuxhomekeke kakhulu ku: 1) isakhiwo sesiseko esomeleleyo esasaza uxinzelelo lokungcangcazela ukusuka kwi-PCB ukuya kwisiseko sonke; 2) ukulungiswa okuqinileyo kwephakheji ye-internal core ukuthintela intshukumo ye-electrode yangaphakathi; kunye 3) i-potting compound esebenza kakhulu ukuze iqhubeke nokubopha kunye nokufunxa amandla okungcangcazela. Olu yilo luneenxantathu luhlangene lufezekisa inqanaba elikhulu ekuchaseni ukungcangcazela.
5. Q: Zeziphi iingxaki ezijongene nee-capacitors kubaqhubi beempompo zamanzi/zeoyile kwiinkqubo zolawulo lobushushu beemoto (ezifana nobushushu obuphezulu kunye nomsinga omkhulu we-ripple)? UYung-Ming ujongana njani nale mingeni?
A: Ii-capacitors ezikwii-water pump/oil pump drivers zihlala zisetyenziselwa ukucoca kunye nokufaka i-buffer kwi-inverter output, zijongene nemisinga emikhulu ye-ripple eyenziwe kukutshintsha kwe-high-frequency, amaqondo obushushu aphezulu e-injini, kunye nokungcangcazela kwe-injini ngokwayo. Iimveliso zethu, ezinomthamo wazo we-ripple current ophezulu, umlinganiselo wobushushu ophezulu we-105°C/125°C, kunye nokumelana nokutshayiswa kwe-10-30g, zinokusebenza ngokuzinzileyo kwiimeko ezinzima kangaka, ukuqinisekisa ukuchaneka kunye nokuthembeka kolawulo lwemoto.
6: Q: Kwiinkqubo ezibalulekileyo zokhuseleko ezifana ne-Electric Power Steering (EPS), zeziphi iindlela zokungaphumeleli kwee-capacitors? I-Yongming ikwenza njani ukuba ukungaphumeleli okubulalayo njengeesekethe ezimfutshane kunye neesekethe ezivulekileyo kuphepheke?
A: Kwi-EPS, ukusilela kwe-capacitor (ingakumbi ii-short circuits) kunokukhokelela ekuphazamisekeni kwenkqubo. Siphucula ukuthembeka ngeendlela ezilandelayo: 1) Ukusebenzisa izinto eziluhlaza ezicocekileyo kakhulu kunye nolawulo oluqinileyo lwenkqubo ukunciphisa ukungcola kwangaphakathi; 2) Uyilo lwevalvu olungenakuqhuma (nangona luhlobo lokufakelwa kumphezulu, lunendlela yokunciphisa uxinzelelo kwisakhiwo salo); 3) Umbane onyukayo we-100% kwaye umelana novavanyo lwe-voltage ukususa ukusilela kwangethuba. Ngaphezu koko, ukumelana kwayo okugqwesileyo kokutshayiswa kuthintela ngokuthe ngqo ukwaphuka kwangaphakathi (ii-open circuits) okanye ii-short circuits ezibangelwa kukungcangcazela.
7: Q: Kwinkqubo yokulawula ukubhabha kweenqwelo-moya ezisezantsi, yintoni umsebenzi ophambili wee-capacitors? Ngaba zisetyenziselwa ukucoca amandla, ukugcina amandla, okanye ukudibanisa isignali?
A: Isetyenziswa kakhulu kwiisekethe zombane zeekhompyutha zolawulo lokubhabha kunye nabaqhubi beemoto ze-servo, isebenza njengomlawuli wevolthi, isihluzi, kunye nomboneleli we-instantaneous pulse current. Iinkqubo zolawulo lokubhabha zinemfuno ephezulu kakhulu yokucoceka kwevolthi kunye nokuphendula kwangoko; ukusebenza okuzinzileyo kwe-capacitor kubalulekile ekuqinisekiseni idatha ye-sensor echanekileyo kunye nempendulo ye-servo ekhawulezayo.
8: Q: I-spectrum yokungcangcazela ebangelwa lutshintsho lokuhamba komoya olufunyanwa zinqwelo-moya iyinkimbinkimbi. Ngaba le mveliso ilungiselelwe ukungcangcazela kuluhlu oluthile lwamaza (umz., 50Hz-2000Hz)?
A: Ewe, uvavanyo lwethu lokungcangcazela lugubungela uluhlu oluqhelekileyo lwefrikhwensi ebanzi (umz., 10Hz ukuya kwi-2000Hz), ngakumbi kwiibhendi zefrikhwensi eziphakathi ukuya kweziphezulu ezinxulumene nemithombo eqhelekileyo yokungcangcazela kweenqwelo moya (umz., iimoto, iipropellers). Ngokusebenzisa uyilo lwesakhiwo, ifrikhwensi yayo evakalayo iyaziphepha ezi bhendi zefrikhwensi zibalulekileyo, ngaloo ndlela igcina ukusebenza phantsi kweemeko ezinzima zokungcangcazela.
9: Umbuzo: Iinqwelo-moya ezisezantsi zinovelwano kakhulu kubunzima. Le capacitor ifikelela njani kukumelana nokungcangcazela okuphezulu ngelixa ilawula ubunzima bayo kunye nobukhulu bayo? Ngaba kukho uyilo olukhaphukhaphu?
A: Silinganisela ukumelana nokungcangcazela kunye ne-miniaturization ngexesha lenkqubo yoyilo. Ngokusebenzisa i-foil ye-electrode ene-capacitance ephezulu ukunciphisa umthamo wephakheji eyintloko ukuze kube namandla afanayo, nangokuphucula ubungakanani bezinto ezisisiseko kunye nezixhobo zokugquma, ngelixa sihlangabezana nomlinganiselo wokumelana nokutshayiswa we-10-30g, umthamo wayo kunye nobunzima bayo zihlala zikwinqanaba elifanayo neemveliso zesiqhelo zeenkcukacha ezifanayo, zihlangabezana neemfuno ezilula zeenqwelo-moya.
10Q: Xa kuthelekiswa nee-capacitors eziqinileyo, ii-capacitors ezingamanzi zihlala ixesha elide (i-electrolyte yomile). UYung-Ming uyiphelisa njani le ngxaki?
A: Sandisa ubomi ngokusebenzisa ubuchwepheshe obubini obuphambili: 1) sisebenzisa i-electrolyte edibeneyo ene-flash voltage ephezulu kunye noxinzelelo lomphunga oluphantsi ukunciphisa ilahleko yomphunga kumaqondo obushushu aphezulu; 2) sisebenzisa isithinteli serabha sokutywina esisebenza kakuhle ukunciphisa kakhulu ukuvuleka kwe-electrolyte. Oku kwandisa kakhulu ubomi be-capacitors zethu ezingamanzi kumaqondo obushushu aphezulu.
