Pehea e pale aku ai i ka charger on-board o kahi EV mai nā piʻi ʻana o ka grid transient

Ka Ma luna o ka PapaLuna hoʻoili(OBC) pilikia i ka wāHoʻopiʻi EVma muli o ka ʻike ʻana i nā hanana overvoltage e hiki mai ana ma ka pā mana. Pono ka hoʻolālā e pale i ka mana semiconductor mai nā overvoltage transients no ka mea hiki ke hōʻino ʻia nā volta ma luna o ko lākou palena kiʻekiʻe. No ka hoʻonui ʻana i ka hilinaʻi a me ke ola o ka EV, pono nā mea ʻenekinia e hoʻoponopono i ka piʻi ʻana o nā koi o kēia manawa a me ka haʻahaʻa haʻahaʻa o ka uila clamping i kā lākou hoʻolālā.

ʻO nā kumu kumu o ka piʻi ʻana o ka volta transient penei:
Ka hoololi ana i na haawe capacitive
Ke hoʻololi nei i nā ʻōnaehana uila haʻahaʻa a me nā kaapuni resonant
ʻO nā kaapuni pōkole ma muli o ke kūkulu ʻana, nā ulia kaʻa, a i ʻole nā ​​ʻino
ʻO nā fuse i hoʻoulu ʻia a me ka pale overvoltage.
Kiʻi 2. Manaʻo Kaapuni no ka ʻokoʻa a me ke ʻano maʻamau Transient Voltage Circuit Protection me ka hoʻohana ʻana i nā MOV a me kahi GDT.

ʻOi aku ka 20mm MOV no ka hilinaʻi maikaʻi a me ka pale. Hoʻohana ka 20mm MOV i 45 pulses o 6kV/3kA surge current, ʻoi aku ka ikaika ma mua o ka 14mm MOV. Hiki i ka diski 14mm ke lawelawe ma kahi o 14 mau haʻalulu i kona wā e ola ana.
Kiʻi 3. Hoʻopili ʻana i ka hana ʻana o ka liʻiliʻi lnfuse V14P385AUTO MOV Ma lalo o 2kV A me 4kV Piʻi. ʻOi aku ka Voltage Clamping 1000V.
Hoʻoholo koho laʻana

Papa 1 Charger—120VAC, kaapuni hoʻokahi-phase: ʻO ka mahana ambient i manaʻo ʻia he 100°C.

E aʻo hou e pili ana i ka hoʻohana ʻana i ka SIDACt a i ʻole Protection Thyristors manā kaʻa uila, e hoʻoiho i ka palapala noi Pehea e koho ai i ka ʻOi aku ka palekana Transient Surge Protection no EV On-Board Chargers, ʻoluʻolu a Little fuse, Inc.
