Kushandiswa kwemafirimu capacitors mumotokari yemagetsi OBC: YMIN capacitor sarudzo chirongwa

Paunenge uchikurukura zvitsva uye kuvandudzwa kwemagadzirirwo emagetsi emotokari dzemagetsi, kutarisa kunowanzoiswa pazvikamu zvakakosha zvakadai sechikamu chikuru chekutonga nemagetsi emagetsi, nepo zvikamu zvekubatsira se capacitors zvinowanzogamuchira zvishoma. Nekudaro, izvi zvekubatsira zvikamu zvine chekuita nemhedzisiro pakuita kwese kwehurongwa. Ichi chinyorwa chichaongorora mashandisirwo eYMIN firimu capacitor mune onboard charger uye kuongorora kusarudzwa uye kushandiswa kwemacapacitor mumotokari dzemagetsi.

Pakati pemhando dzakasiyana dze capacitors,aluminium electrolytic capacitorsvane nhoroondo refu uye vakabata chinzvimbo chakakosha mumunda wemagetsi emagetsi. Nekudaro, nekushanduka kwezvinodiwa zvetekinoroji, izvo zvinogumira zve electrolytic capacitors zvave kuwedzera kuoneka. Somugumisiro, imwe nzira yepamusoro-yefirimu capacitor-yakabuda.

Kuenzaniswa ne electrolytic capacitors, mafirimu capacitors anopa zvakakosha zvakakosha maererano nevoltage endurance, yakaderera yakaenzana yakatevedzana kuramba (ESR), isiri-polarity, kugadzikana kwakasimba, uye hupenyu hurefu. Aya maitiro anoita kuti mafirimu capacitor ave akatanhamara mukurerutsa sisitimu dhizaini, kusimudzira ripple ikozvino kugona, uye nekupa kuita kwakaringana kuita pasi pemamiriro ekunze akaomarara.

Tafura: Kuenzanisa kuita kwakanakira kwemafirimu capacitorsuye aluminium electrolytic capacitors

 

Nokuenzanisa kushanda kwemafirimu capacitors nemamiriro ekushandiswa kwemotokari yemagetsi, zviri pachena kuti kune hupamhi hwekuenderana pakati pezviviri. Sezvo zvakadaro, mafirimu capacitors hapana mubvunzo kuti zvikamu zvinosarudzwa mukugadzirisa magetsi emotokari dzemagetsi. Nekudaro, kuti ive nechokwadi chekukodzera kwavo kushandiswa kwemotokari, aya macapacitor anofanirwa kusangana neyakaomarara miyero yemotokari, senge AEC-Q200, uye kuratidza kuita kwakavimbika pasi pemamiriro akanyanya. Zvichienderana nezvinodiwa izvi, kusarudzwa uye kushandiswa kwema capacitors kunofanirwa kutevedzera iyi misimboti.

 

01 Mafirimu capacitors muOBC

An OBC (On-Board Charger) system inowanzove nezvikamu zviviri zvikuru: rectifier circuit inoshandura AC mains simba kuita DC, uye DC-DC inoshandura magetsi inogadzira inodiwa DC voltage yekuchaja. Mukuita uku,mafirimu capacitorstsvaga application munzvimbo dzakati wandei, kusanganisira:

02 Mamiriro ekushandisa emafirimu capacitors muOBC

EV OBC DC-link MDP(H)
Sefa yekubuda Input Sefa MDP

YMINinopa huwandu hwemafirimu capacitor zvigadzirwa akakodzera DC-Link uye inobuda kusefa maapplication. Zvikuru, zvese izvi zvigadzirwa ndezveAEC-Q200 mota-giredhi yakasimbiswa. Pamusoro pezvo, YMIN inopa yakasarudzika mhando dzakagadzirirwa kukwirisa-tembiricha uye yakakwirira-humidity (THB) nharaunda, ichipa vanogadzira kuchinjika kukuru mukusarudza kwechikamu.

DC-Link Capacitors

Mune OBC sisitimu, DC-Link capacitor yakakosha pakutsigira ikozvino uye kusefa pakati peiyo rectifier wedunhu uye DC-DC inoshandura. Basa rayo rekutanga nderekutora mapuruzi akakwira pabhazi reDC-Link, kudzivirira kukwira kwemhepo pamhepo yeDC-Link uye kudzivirira mutoro kubva pakuwedzeredza.

Masikirwo emufirimu capacitor-akadai seyakakwira voltage kushivirira, yakakura capacitance, uye isiri-polarity-inoaita akanakira DC-Link kusefa maapplication.

YMIN'sMDP(H)akatevedzana isarudzo yakanakisa yeDC-Link capacitors, inopa:

  • Capacitance kukosha kusvika ku500μF
  • Yakaderera ESR uye yepamusoro ripple ikozvino kubata
  • Hupenyu hunopfuura maawa e100,000
  • Tembiricha yepamusoro yekushanda inosvika 125°C, nekugona kwenguva pfupi pa150°C

Output Sefa Capacitors

Kuti uwedzere hunhu hwekupindura hwenguva pfupi yeOBC's DC inobuda, yakakura-capacitance, yakaderera-ESR inobuda sefa capacitor inodiwa. YMIN inopa iyoMDPlow-voltage DC-Link film capacitors, ine:

  • Capacitance kukosha kusvika ku500μF
  • Yakasiyana-siyana yakayerwa magetsi (500Vdc kusvika 1500Vdc)

Izvi zvigadzirwa zvinopa kuita kwakakasharara, kuvimbika, uye kuchinjika kune inoda mota application, kuve nechokwadi chekushanda uye kwakagadzikana OBC kushanda.

03 Mhedziso

Sezvinoratidzwa nekuongorora kuri pamusoro, mafirimu capacitors ari kuwedzera kufarirwa nevainjiniya muindasitiri yesimba rinogoneka nekuda kweyavo yakasarudzika mabhenefiti uye akabatanidzwa zvakanyanya mumhinduro dzine hukama. Kunyanya mukugadzirwa kwemotokari, maitiro ekushandisa emafirimu capacitors ave kuwedzera mukurumbira.
