Nā mea nui o ka ʻōnaehana mālama ikehu -IGBT

ʻO ke kumu kūʻai o ka ʻōnaehana mālama ikehu ka mea nui i haku ʻia me nā pākaukau a me nā mea hoʻohuli i ka ikehu. ʻO ka huina o nā mea ʻelua he 80% o ke kumukūʻai o ka ʻōnaehana mālama ikehu electrochemical, kahi o 20%. ʻO ka IGBT insulating grid bipolar crystal ka mea maka mua o ka mea hoʻohuli i ka ikehu. Hoʻoholo ka hana o IGBT i ka hana o ka inverter mālama i ka ikehu, helu no 20% -30% o ka waiwai o ka inverter.

ʻO ka hana nui o IGBT ma ke kahua o ka mālama ʻana i ka ikehu ka transformer, ka hoʻololi pinepine, ka hoʻololi ʻana o ka intervolution, a me nā mea ʻē aʻe.

ʻO nā mea maka o luna o nā mea hoʻololi e mālama ai i ka ikehu, ʻo ia ka IGBT, capacitance, resistance, electric resistance, PCB, etc. Aia nō ka ʻokoʻa ma waena o ka IGBT kūloko ma ka pae ʻenehana a me ka pae alakaʻi o ka honua. Eia nō naʻe, me ka hoʻomohala wikiwiki ʻana o ka ʻoihana mālama ikehu o Kina, ua manaʻo ʻia ke kaʻina hana home o IGBT e wikiwiki.

IGBT ikehu waihona noi waiwai

Ke hoʻohālikelike ʻia me ka photovoltaic, ʻoi aku ka kiʻekiʻe o ka waiwai o ka mālama ʻana i ka ikehu IGBT. Hoʻohana ʻia ka mālama ʻana i ka ikehu i ka IGBT a me SIC, e pili ana i ʻelua mau loulou: DCDC a me DCAC, me nā hopena ʻelua, ʻo ia hoʻi ka optical storage integrated a me ka ʻōnaehana mālama ikehu kaʻawale. ʻO ka ʻōnaehana mālama ikehu kūʻokoʻa, ʻo ka nui o nā mana semiconductor mana ma kahi o 1.5 mau manawa i ka photovoltaic. I kēia manawa, ʻoi aku ka nui o ka mālama ʻana i ka optical ma mua o 60-70%, a ʻo kahi ʻōnaehana mālama ikehu kaʻawale no 30%.

Kiʻi: BYD IGBT module

Loaʻa i ka IGBT kahi ākea o nā papa noi, ʻoi aku ka maikaʻi ma mua o MOSFET i ka inverter mālama mālama. Ma nā papahana maoli, ua hoʻololi mālie ʻo IGBT i ka MOSFET ma ke ʻano he mea nui o nā inverters photovoltaic a me ka hoʻokumu ʻana i ka makani. ʻO ka hoʻomohala wikiwiki ʻana o ka ʻoihana hana mana ikehu hou e lilo i mea hoʻokele hou no ka ʻoihana IGBT.

ʻO IGBT ka mea nui no ka hoʻololi a me ka lawe ʻana i ka ikehu

Hiki ke hoʻomaopopo piha ʻia ʻo IGBT ma ke ʻano he transistor e hoʻomalu i ka uila ʻelua ala (multi-directional) e kahe ana me ka mana valve.

ʻO ka IGBT kahi mea hana semiconductor mana piha piha-control-driven i haku ʻia me ka BJT bipolar triode a me ka insulating grid field effect tube. ʻO nā pōmaikaʻi o nā ʻano ʻelua o ka hāʻule kaomi.

ʻO ka hana hoʻololi o IGBT ka hana ʻana i kahi ala ma ka hoʻohui ʻana i ka maikaʻi i ka volta puka e hāʻawi i ke kumu kumu i ka transistor PNP e hoʻokele IGBT. ʻO ka mea ʻē aʻe, e hoʻohui i ka volta puka inverse e hoʻopau i ke kahawai, e kahe i ke kumu hope o kēia manawa, a hoʻohuli i ka IGBT. ʻO ke ala hoʻokele o IGBT ka mea like me ka MOSFET. Pono wale ia e hoʻomalu i ka pou komo N hoʻokahi -channel MOSFET, no laila he mau hiʻohiʻona impedance kiʻekiʻe.

ʻO IGBT ka mea nui o ka hoʻololi a me ka hoʻoili ʻana o ka ikehu. ʻIke ʻia ʻo ia ka "CPU" o nā mea uila uila. Ma ke ʻano he ʻoihana hoʻolālā hoʻolālā aupuni, ua hoʻohana nui ʻia i nā lako ikehu hou a me nā ʻano ʻē aʻe.

He nui nā pono o ka IGBT me ka impedance hoʻokomo kiʻekiʻe, ka mana mana haʻahaʻa, ke kaʻa kaʻa kaʻa maʻalahi, ka wikiwiki hoʻololi wikiwiki, ka nui o ka mokuʻāina, ka hoʻohaʻahaʻa ʻana i ke kaomi ʻana, a me ka pohō liʻiliʻi. No laila, loaʻa iā ia nā mea maikaʻi loa i ka mākeke mākeke o kēia manawa.

No laila, ua lilo ʻo IGBT i mea nui loa o ka mākeke semiconductor mana o kēia manawa. Hoʻohana nui ʻia ia ma nā wahi he nui e like me ka mana hou o ka ikehu, nā kaʻa uila a me nā puʻu hoʻopiʻi, nā moku uila, ka hoʻouna ʻana o DC, ka mālama ʻana i ka ikehu, ka mana uila ʻenehana a me ka mālama ʻana i ka ikehu.

IGBT hoʻokaʻawale

Wahi a ke ʻano o nā huahana like ʻole, ʻekolu mau ʻano IGBT: hoʻokahi -pipe, module IGBT a me ka module mana akamai IPM.

(Ka hoʻouka ʻana i nā pila) a me nā māla ʻē aʻe (ka hapa nui o nā huahana modular i kūʻai ʻia ma ka mākeke o kēia manawa). Hoʻohana nui ʻia ka module IPM naʻauao ma ke kahua o nā mea pono home keʻokeʻo e like me ka inverter air conditioners a me nā mīkini holoi hoʻololi pinepine.

Ma muli o ka volta o ka hiʻohiʻona noi, loaʻa i ka IGBT nā ʻano e like me ka ultra-low voltage, low voltage, medium voltage and high voltage.

Ma waena o lākou, ʻo ka IGBT i hoʻohana ʻia e nā kaʻa ikehu hou, ka mana o ka ʻoihana, a me nā mea hana hale ka nui o ka uila uila, ʻoiai ke kaʻa kaʻaahi, ka mana o ka mana hou a me nā grids akamai he kiʻekiʻe o nā koi uila, ʻoi aku ka hoʻohana ʻana i ke kiʻekiʻe-voltage IGBT.

Hōʻike ka IGBT ma ke ʻano o nā modula. Hōʻike ka ʻikepili IHS i ka hapa o nā modules a me ka pahu hoʻokahi he 3: 1. ʻO ka module he huahana semiconductor modular i hana ʻia e ka chip IGBT a me ka FWD (hoʻomau i ka diode chip) ma o kahi alahaka kaapuni i hoʻopili ʻia, a ma o nā papa plastik, substrates a me nā substrates. , etc.
