Imvelo yezimoto ingenye yezindawo ezinzima kakhulu ze-elekthronikhi. NamuhlaAmashaja we-EVImiklamo eyanda nge-Electronics ebucayi, kufaka phakathi izilawuli ze-elekthronikhi, infotainment, ukuzwela, amaphakethe webhethri, ukuphathwa kwebhethri,Iphoyinti Lemoto kagesi, namashaja asebhodini. Ngaphezu kokushisa, ama-voltage anamthamo, kanye nokuphazanyiswa kwe-electromagnetic (i-EMI) endaweni yezimoto, i-On-board Charger kumele iboniswe ngegridi yamandla e-AC, edinga ukuvikelwa kusuka ekusebenzeni komugqa we-AC kokusebenza okuthembekile.
Abakhiqizi banamuhla bengxenye banikela ngamadivayisi amaningi okuvikela amasekethe we-elektroniki. Ngenxa yokuxhumeka kugridi, ukuvikelwa kweshaja ebhodini kusuka ku-Voltage Surtes usebenzisa izakhi ezihlukile kubalulekile.
Isixazululo esiyingqayizivele sihlanganisa i-sidactor kanye ne-varistor (i-SMD noma i-THT), ifinyelela amavolumu aphansi aphansi ngaphansi kokudonswa okuphezulu okuphezulu. I-Sidactor + Mov Combination inika amandla onjiniyela bezimoto ukuthi basebenzise ukukhetha ngakho-ke, izindleko zama-semiconductors e-design. Lezi zingxenye ziyadingeka ukuguqula i-ac voltage ibe yi-voltage ye-DC ukukhokhisa imotoUkushaja kwebhethri ebhodini.
Umdwebo 1. I-On-Board Charger Block Block DIAGRAM
The-boardIjatshi(OBC) usengozini ngesikhathiUkushaja kwe-EVNgenxa yokuchayeka ezenzakalweni ezingaphezulu kwegridi yamandla. Idizayini kumele ivikele ama-semiconductors anamandla ezintandelweni ze-stervoltage ngoba ama-voltage angenhla kwemikhawulo yawo ephezulu angayilimaza. Ukwelula ukuthembeka kwe-EV kanye nesikhathi sokuphila, onjiniyela kufanele babhekane nokwanda kokuhlinzwa kwezidingo zamanje namandla aphansi aphezulu wokubopha amandla emiklamo yawo.
Imithombo ye-Voltage Sources ye-Transient ifaka okulandelayo:
Ukushintshwa kwemithwalo ye-capacitive
Ukushintshwa kwezinhlelo eziphansi ze-voltage kanye namasekethe akhona
Imibuthano emifushane evela ekwakhiweni, ezingozini zomgwaqo, noma izivunguvungu
Kubangelwa ama-fuses kanye nokuvikelwa ngokweqile.
Umdwebo we-2. Kunconywe umjikelezo we-Mode Ehlukile futhi evamile ye-Mode Voltage Voltage Voltage evikelekile usebenzisa ama-Movs ne-GDT.
I-20mm mov ilindelwe ukuthembeka okungcono nokuvikelwa. I-20mm Mov iphatha ama-pulses angama-45 we-6kv / 3ka ahlele ngokuqinile, okunamandla kakhulu kune-14mm mov. I-14mm disc ingaphatha kuphela ukuzungeza okungu-14 ngaphezulu kwesikhathi sayo sokuphila.
Umdwebo 3. Ukuqubuka ukusebenza kweLenLuse V14P385uuto mov ngaphansi kwe-2KV kanye ne-4KV Surges. I-clamping voltage idlula i-1000V.
Isibonelo Ukukhetha Ukuzimisela
Izinga le-1 charger-120VAC, umjikelezo wesigaba esisodwa: izinga lokushisa elilindelwe elindelekile lingu-100 ° C.
Ukuze ufunde kabanzi ngokusebenzisa i-sidact noma ukuvikelwa kwe-Jeyristors ku-Izimoto zikagesi, landa indlela ongayikhetha kanjani isivikelo esiphezulu sokuhlelwa kwesikhashana kwe-EV On-board Chargers Inothi, ngoncedo lwe-Little Fuse, Inc.
