Ukuqhekeza ii-Capacitors eziQinisekileyo ze-YMIN ze-ESR eziphantsi: Ukusuka kwiingenelo zeParameter ukuya kwiNtsebenzo yokwenyani, Ungawupholisa njani kwaye uphucule ukusebenza kakuhle kuYilo loNikezo lwaMandla?

Intshayelelo

Iinjineli zombane ezithandekayo, ngaba wakha wakhathazwa zii-capacitor ezihlala ziphezulu kunye nokushisa kakhulu xa ulungisa iiprototypes? Ingakumbi ekufuneni amandla aphezulu, i-ESR kunye nobuchule bamandla e-ripple ye-capacitors ziye zaba yimiqobo engabonakaliyo emisela impumelelo okanye ukungaphumeleli koyilo. Eli nqaku liza kuthatha uthotho lwe-VPX/VPT lwe-YMIN njengomzekelo wohlalutyo olunzulu lobuchwephesha, olubonisa indlela olusombulula ngayo la manqaku entlungu ngedatha ebonakalayo.

Isisombululo se-YMIN kunye neeNzuzo

Ukuthatha itshaja eqhelekileyo ye-65W 2C2A GaN fast njengomzekelo, kufuneka iphathe amaza okutshintsha afikelela kumakhulu aliqela e-kHz kwindawo evalekileyo. Ukuba kusetyenziswa ii-capacitors eziqinileyo eziqhelekileyo (ESR malunga ne-40mΩ), ukulahleka kwazo kumaza aphezulu akufuneki kuthathelwe ingqalelo. Siqaphele ukuba phantsi komthwalo opheleleyo, ubushushu obuphambili bee-capacitors ezinjalo bunokudlula i-85℃, nto leyo engeyiyo nje kuphela ingozi yokhuseleko lobushushu kodwa ikwabangela ukubola kwe-capacitance kunye nokunyuka kwe-ESR ngenxa yobushushu obuphezulu, nto leyo ephakamisa imibuzo malunga nokuthembeka kwexesha elide.

Ingxaki ephambili ikwi-ESR. Ukulahleka kwamandla P_loss = I_rms² × ESR. Xa i-switching frequency inyuka iye kwi-100kHz, i-capacitive reactance (Xc) iyancipha kakhulu, kwaye i-ESR iba yinxalenye ephambili ye-impedance. Xa kuthathwa i-capacitor ene-ESR ye-40mΩ ephethe i-2A ripple current njengomzekelo, ukulahleka kwayo kweseli enye kuphezulu njenge-0.16W. Kwindawo encinci, obu bushushu kunzima kakhulu ukubuchitha.Isisombululo se-YMINkunciphisa i-ESR ukuya kwi-20mΩ, kunciphisa ilahleko ukuya kwi-0.08W phantsi kweemeko ezifanayo, kunciphisa ngokuthe ngqo ukuveliswa kobushushu kwaye kusombulula ingxaki yokunyuka kobushushu ngokusisiseko.

- Isisombululo se-YMIN kunye neeNzuzo zeNkqubo: Utshintsho oluphindwe kabini kwiZixhobo kunye noLwakhiwo -

I-ESR ephantsi ye-YMIN ayisiyongozi, kodwa yimiphumo yobunjineli obucwangcisiweyo:

Utshintsho lwe-Electrolyte: Sisebenzisa i-polymer ene-patent high-conductivity polymer, i-ionic conductivity inyuswa ngaphezulu kwe-30%, okuqinisekisa ukuba i-ion migration impedance iphantsi kakhulu kumaza aphezulu.

Ukuphucula i-Anode Foil: Ngokusebenzisa i-electrochemical etching, kwakheka isakhiwo esifana ne-tunnel-porous, nto leyo eyenza indawo yomphezulu ibe ngcono kwaye iphucule i-instantaneous charge throughput.

Ulwakhiwo oluphantsi lokumelana kwangaphakathi: Uyilo oluphantsi lokumelana kuyo yonke inkqubo, ukusuka kwityesi ye-aluminiyam kunye neplagi yerabha ukuya kwiileyiti, kunciphisa ukumelana okungafunekiyo kwe-parasitic kunye ne-inductance.

- Ingxelo yokuqinisekiswa kwedatha kunye nokuthembeka kwayo: Vumela idatha izithethele ngokwayo -

Sithelekise idatha yovavanyo lwee-capacitors eziqinileyo ze-YMIN VPX 25V 100μF ngaphambi nasemva kokutsalwa kwakhona kwe-soldering. Izinga lotshintsho lwe-ESR lilonke lilawulwa ngaphakathi koluhlu oluthile. Ukunyuka kwexabiso layo le-ESR kwakuyi-15.1% kuphela. Oku kubonisa uzinzo oluhle kakhulu lobushushu bemveliso kunye nokuthembeka kwenkqubo, okuqinisekisa ukusebenza kombane okuzinzileyo nasemva kokuhlanganiswa kwe-SMT.

Imizekelo yezicelo zehlabathi lokwenyani

Umzekelo, itshaja ekhawulezayo yeBaseus 65W GaN isebenzisaUthotho lwe-YMIN VPX,ukusasazwa kobushushu okusebenzayo kunye nemveliso ezinzileyo ezibonisa ngokupheleleyo ezi parameters zokusebenza kwimveliso yokugqibela.

Isiphelo

Kwiinjineli ezifuna ukusebenza okuphezulu, ixabiso le-ESR le-capacitor enye linokuba yinto ethatha isigqibo ekusebenzeni kwenkqubo iyonke. I-YMIN Electronics iyaqonda oku kakuhle, kunye nokubekwa kwayo kwindawo ethi “Kwizicelo ze-capacitor, jonga kuI-YMIN yezisombululo"Isekelwe kubuchule bayo bokusombulula iingxaki zobugcisa ezinzima. Ngokubonelela ngeemveliso eziphezulu ezinee-ESR eziphantsi njenge-20mΩ, i-YMIN ifezekisa ngokuthe ngcembe injongo yayo yemveliso "yokutshintsha abakhuphisana nabo bamazwe ngamazwe kwaye ibe luphawu oluphambili," ibonelela abayili bombane basekhaya ngezisombululo zecandelo leetshiphusi ezibalaseleyo nezithembekileyo eziveliswe apha ekhaya.
