Ma capacitor emagetsi epamusoro ane tekinoroji yekuzvirapa inodzorwa ndeimwe yemhinduro dzemagetsi emagetsi dzinogona kushandiswa nemainjiniya eEV neHEV kuti dzisangane nehukuru hwakasimba, huremu, mashandiro, uye kuvimbika kwemusika uyu unoda simba.
Ma capacitor emagetsi emagetsi anokwanisa kupa mhinduro dzekugadzira dzakavimbika dzeEV neHEV dzinofanira kusangana nematanho akati wandei maererano nezvinhu zvefirimu zvakagadzirwa nesimbi, kugadzirisa, uye dhizaini.
Chinhu
Kubudirira kunogara kwenguva refu kwave chinhu chakakosha uye chiripo nguva dzese munguva ino. Kunyanya, muindasitiri yesimba, mhinduro dzesimba rakachena, rinodzokororwa dziri kutsiva nzira dzechinyakare dzinoshandisa mafuta. NeEV neHEV zviri musika uri kukura, ma inverters anofanirwa kunge aine saizi diki, simba rakawanda, gap yakafara (WGB) uye zero-catastrophic-failure kuitira kutsiva injini yemukati yekupisa yetsika (ICE). Nekuda kweizvozvo, metalized film capacitor chinhu chakakosha kuti EV neHEV yeramangwana zvizadzise zvinodiwa pamusika.
Metalized film capacitor kuCRE ine hunhu hwekuzviporesa, kugona kudzivirira kutadza kukuru kana paine dambudziko remukati. Dielectric film iri mu capacitor yedu yakafukidzwa nezvinhu zvesimbi zvinoiswa mu vacuum uye zvine ukobvu hwema nanometers gumi nemaviri. Kana paine nzvimbo isina kusimba kana kusachena pa dielectric, kuputsika kuchaitika. Simba rinoburitswa nekubuda kwe arc pakuputsika richakwana zvakakwana kuti simbi yakakomberedza iparare, iparadzanise dambudziko racho uye iporese capacitor kuti irambe ichishanda zvakanaka.
Nehunyanzvi uhwu hwekuzvirapa, macapacitor edu esimbi anoshandiswa pakugadzira mafirimu anoshandiswa pamusika uye anokwanisa kuzadzisa zvinodiwa zvemagetsi zvemhando yepamusoro kusanganisira ma inverters anoshandiswa mu EV ne HEV. Ane tarisiro yehupenyu hurefu uye akavimbika pasina kukanganisa kukuru. Kuwedzera kune zvakanakira zvinobva mukuzvirapa, ma capacitor edu madiki zvakare ane capacitance yakakura. Anogona kuiswa zviri nyore uye anogona kuramba simba remagetsi rakawanda.
Ma capacitor efirimu ane simbi anoiswa nemagadzirirwo eCRE patent. Anowanzoiswa ne resin yakaoma, obva avharwa ne tepi yeMyra uye ovharwa nesimbi kana purasitiki. Dhizaini ye patent iyi inounza mabhenefiti akasiyana-siyana anosanganisira kuyera magetsi ne inductance, hapana kuwedzera kwekupisa kwakanyanya, simba remagetsi rakawanda uye mutengo wakaderera wekugadzira. Ma capacitor akawanda anogona kusungirirwa mubhawa rebha kuti ape self-inductance yakaderera iyo inogona kushandiswa kuderedza over-voltage panguva yekuchinja.
Seimwe yemhinduro dzemafambiro esimba rakachena uye budiriro inoenderera mberi, musika weEV neHEV unotarisirwa kuramba uchikura uye pakupedzisira kutsiva maICE models. Ma metalized film capacitors kuWuxi CRE achava mhinduro inoshanda, yakavimbika uye inotungamira mukugadzirwa kwako mune ramangwana.
