Mubvunzo: Panguva yekuchaja mota itsva ine simba, dashboard kana central control screen inodzima kana kutangazve kwechinguva. Chii chingave chikonzero?
A: Chiitiko ichi chingangoitika nekuti panguva yekuchaja mota, bhatiri remagetsi rinodzima magetsi kwenguva pfupi kuti riongorore kuchengetedzeka. Panguva ino, michina yemagetsi ine voltage shoma yemotokari yese (senge dashboard uye infotainment system) inotsamira zvachose paDC-DC converter. Kana capacitance paDC-DC output isina kukwana kana kusagadzikana, haigone kuzadza simba nenguva apo mutoro unowedzera kamwe kamwe, zvichikonzera kudzikira kwechinguva kwevoltage inobuda uye zvichikonzera kupenya kwechiso. YMIN VHT/VHU series automotive-grade capacitors ine capacitance yavo inodzorwa zvakasimba mukati mehuwandu hwepamusoro hweindasitiri hwe0~+20%, zvichiita kuti capacitor yega yega igone kupa simba rakakwana uye rakagadzikana, zvichibvisa matambudziko ekudonha kwevoltage anokonzerwa nekusakwana kwecapacitance kana kupararira kukuru.

Q: Ungasarudza sei ma capacitor echikamu che output filter cheDC-DC converter mumotokari itsva yesimba kuti uve nechokwadi chekuti magetsi agadzikana?
A: Chinhu chikuru pakusarudza capacitor chiri mukugadzikana kwayo kwe capacitance uye kushivirira kwe ripple current. Chekutanga, capacitance yakayerwa ye capacitor inofanira kunge yakakura zvakakwana kuchengetedza kugadzikana kwe voltage pasi pemitoro yakasiyana-siyana. Chinonyanya kukosha ndechekuti capacitance chaiyo inofanira kusiyana zvishoma kubva pa nominal value. YMIN automotive-grade capacitors, kuburikidza nekudzora kwakasimba kwe process, inodzora zvakananga capacitance deviation mukati me 0 ~ + 20% (zviri nani pane indasitiri-common ± 20%). Izvi zvinoreva kuti kugadzikana kwesimba kunovimbiswa zviri nyore panguva yekugadzira uye kuyedza, kudzivirira njodzi dzesystem dzinokonzerwa nemiganhu yakaderera ye capacitance.

Mubvunzo: Kusashanda zvakanaka kwema capacitance pakati pema capacitor akasiyana kunotungamira mukuchinja-chinja kwe goho panguva yekuedzwa kweDC-DC board factory. Izvi zvingagadziriswa sei?
A: Iri idambudziko rinowanzo shandiswa pakudzora hunhu hwema "supply chain". YMIN capacitors inoita kuti zvigadzirwa zvayo zvirambe zvakafanana, kunyanya capacitance, nekuisa 100% CCD detection uye bvunzo dzakasimba dzekukwegura mukati memaitiro ese ekugadzira (akadai se riveting, winding, impregnation, uye assembly). Nekudzikamisa capacitance tolerance mukati mechikamu chidiki che0% kusvika +20%, kushanda kwakafanana kwemabhodhi ako eDCDC muma "batches" akasiyana kunovimbiswa, zvichivandudza goho remufekitori uye kuvimbika kwechigadzirwa.

Mubvunzo: Sei kurongeka kwe capacitor capacitance kuchikosha zvikuru mukugadzirwa kweDCDC circuit? Hapana here nzira yekugadzirisa mhinduro?
A: Kunyange zvazvo feedback loop ichigona kugadziriswa, kumhanya kwayo kwekupindura kwakaganhurirwa. Kana yakatarisana nekuchinja kwemutoro we microsecond kana millisecond instantaneous, feedback loop haigone kupindura nenguva. Mumamiriro ezvinhu aya, mutoro wekuchengetedza kugadzikana kwevoltage unowira zvachose pakugona kwe "instantaneous discharge" kwe output capacitor. Kana capacitance chaiyo ye capacitor iri pasi pe design value (semuenzaniso, nominal 330μF capacitor ine kukosha chaiko kwe270μF chete), kuchengetedza kwayo simba hakuzokwani kuti ikwanise kugadzirisa current demands instantaneous, zvichikonzera kudzikira kwevoltage uye kusagadzikana kwesystem. YMIN Capacitors inovimbisa capacitance shoma isiri pasi pe nominal value, ichipa hwaro hwakasimba hwehardware ye high-speed dynamic response yako.

Mubvunzo: Pane ma capacitor emhando yepamusoro emotokari here kana kuti emhando yehybrid anokurudzirwa, anoda capacitance yakakura uye kugara zvakanaka, kuma DC-DC modules mumotokari itsva dzemagetsi dzemhando yepamusoro?
A: Tinokurudzira ma capacitor eYMIN eVHT neVHU series polymer hybrid solid-state capacitors. Iyi nhevedzano yakagadzirirwa mashandisirwo emagetsi emotokari, ichipa kwete chete huwandu hwe capacitance hwakakwira kuti husvike pazvinodiwa zvehukuru, asiwo, chinonyanya kukosha, kushivirira capacitance kwakadzora mukati me0~+20%, zvichiita kuti munhu mumwe nemumwe agare zvakanaka. Semuenzaniso, mamodheru eVHT_35V_330μF neVHU_35V_270μF anoshandiswa zvakanyanya muma converter eDC-DC ane voltage yakawanda mumotokari itsva dzesimba, zvichinyatsoona kuchena uye kugadzikana kwesimba rinobuda uye kusangana nezvinodiwa zvakasimba zvemamodheru emhando yepamusoro.
Mubvunzo Mukuru: Bhodhi redu reDC-DC rinowana magetsi akawanda anobuda mushure mekusonerazve, zvichikonzera kushandiswa kwesimba risingachinji. Pane ma capacitor anochengetedza magetsi mashoma anobuda mushure mekusonera nekupisa kwakanyanya here?

Mubvunzo: Mushure mekusonerazve pamusoro peSMT, simba rinoshandiswa pabhodhi remagetsi reDC-DC rinodarika mwero wezvinodiwa. Kuferefeta kwakaratidza kuti izvi zvinokonzerwa nekuwedzera kwe capacitor leakage current. Izvi zvingadziviswa sei?
A: Iri idambudziko rinowanzoitika muindasitiri, rinobva mukukuvadzwa kudiki kunokonzerwa nemukati me dielectric yema capacitors nekuda kwekumanikidzwa kwekupisa kwakanyanya kwe reflow soldering. YMIN Capacitors inogadzirisa dambudziko iri kuburikidza nezviyero zviviri zvikuru: Chekutanga, maCCD anoiswa mumaitiro akakosha akadai se riveting uye winding panguva yekugadzira kuti aongorore 100% kubvisa zvikanganiso zvekutanga; chechipiri, bvunzo dzakawanda dzakasimba dzekukwegura dzinoitwa usati watumirwa, 100% kubvisa zvigadzirwa zvine leakage current parameters zvinogona kuora mushure mekupiswa nekupisa. Izvi zvinoita kuti ma capacitor anounzwa kufekitori yako, mushure meku reflow soldering, achiri ne leakage current iri pasi pezvinodiwa zvakajairwa, zvichivimbisa kuti kushandiswa kwesimba restandby kunosangana nezvinodiwa.
Rudzi rweMubvunzo: Kuedzwa uye Kusimbiswa
Mubvunzo: Unogona here kupa ruzivo rwekuti leakage current yema capacitor ako inoramba yakagadzikana mushure mekusonerazve?
A: Hongu. Tichitora data rekuyedza reYMIN VHU_35V_270μF_10*10.5 semuenzaniso, bvunzo inoratidza kuti mushure mekusonerazve, avhareji yekuwedzera kwesimba rekubuda kwe100 samples iri pasi pe1μA. Data iri rinoratidza zvizere kugadzikana kwesimba rekubuda kweYMIN capacitors mushure mekusonera kupisa, zvichisangana nezvinodiwa zvakanyanya zvekushandisa simba rakamira.

Mubvunzo: Kuti kuderedze kushandiswa kwesimba remagetsi panguva yekumirira kwemamodule eDC-DC, ndeapi maparameter anofanira kufungwa nezvawo pakusarudza ma capacitor?
A: Kunze kwe capacitance neESR, leakage current chinhu chakakosha, kunyanya mumashandisirwo anoda mwero we standby une simba shoma. Unofanira kutarisisa kwete chete kukosha kwekutanga kwe leakage current pa capacitor datasheet, asi chinonyanya kukosha, kushanda kwayo mushure mekusangana nekupisa kwakanyanya kwekutenderera kwe reflow. Mitemo yekuongorora yefekitori yeYMIN capacitors inosanganisira kudzora kwakasimba pamusoro pechinhu ichi, ichiva nechokwadi chekuti chigadzirwa chinochengetedza leakage current yakaderera mushure mekusungirirwa, nokudaro zvichikubatsira zvakananga kuderedza kushandiswa kwesimba re static remuchina.

Mubvunzo: Zvigadzirwa zvedu zvemagetsi zvemotokari zvine zvinodiwa zvakanyanya zvekukundikana (zvisina kukwana). Ndezvipi zviyero zvekutonga mhando zvinoshandiswa nema capacitor ako kutsigira izvi?
A: YMIN Capacitors inoshandisa sisitimu yekudzora mhando ine "zero-defect". Kunyanya, kudzivirira kuwanda kwekubuda kwemvura, takaisa michina yekuongorora otomatiki yeCCD mumabasa ese akakosha panguva yekugadzira, akadai seriveting, winding, impregnation, uye assembly, kuti tiite ongororo ye100% uye kudzivirira chero zvigadzirwa zvakapera kukuvara kuti zvisapinde mumaitiro anotevera. Chekupedzisira, kuburikidza nemaitiro akawanda ekuongorora anosanganisira power-on older uye parameter testing, tinova nechokwadi chekuti chero zvigadzirwa zvinogona kusangana ne parameter degradation mushure mekugadziriswazve kwe solder panzvimbo yemutengi zvinobviswa pachine nguva. Iyi nzira yakazara yekudzora inopa vimbiso yakasimba yekuvimbika kwako kwakanyanya.
