Teknụzụ ọhụrụ dị nro kwụ ọtọ na ojiji ya na ihe mkpuchi ihe

Kemgbe afọ 1966, EM Technology agbaala mbọ n'inyocha na mmepe nke ihe mkpuchi. Kemgbe afọ 56, a na-akọpụta ihe n'ime ụlọ ọrụ ahụ, e guzobela nnukwu usoro nyocha sayensị, emepụtala ihe karịrị ụdị ihe mkpuchi ọhụrụ iri atọ, na-eje ozi na ike eletrik, igwe, mmanụ ala, kemịkalụ, eletrọniki, ụgbọala, ihe owuwu, ike ọhụrụ na ụlọ ọrụ ndị ọzọ. N'ime ha, itinye n'ọrụ bụ itinye n'ọrụ.nke ihe mkpuchi ihe na igwe ịkpụzi bụkwa otu n'ime ntụziaka ndị bụ isi anyị na-elekwasị anya na ha.

Dịka ọgbọ ọhụrụ nke teknụzụ nnyefe DC, nnyefe DC na-agbanwe agbanwe yiri nnyefe HVDC na nhazi, nke ka nwere ọdụ mgbanwe na ahịrị nnyefe DC. N'adịghị ka ụdị mgbanwe isi mmalite ugbu a nke nnyefe HVDC dabere na teknụzụ mgbanwe nke usoro na-achịkwa, ihe mgbanwe na nnyefe DC na-agbanwe agbanwe bụ ihe mgbanwe isi iyi voltaji (VSC), nke a na-eji ngwaọrụ ndị a na-agbanwe agbanwe (na-abụkarị IGBT) na teknụzụ mgbanwe ugboro ugboro dị elu mara. N'afọ ndị na-adịbeghị anya, nnyefe DC na-agbanwe agbanwe na-etolite ruo ọkwa voltaji na ikike dị elu.

Ọnọdụ ngwa nke IGBT: IGBT juputara na tube bipolar nke nwere mkpuchi, nke enwere ike ịgbanyụ, nwere uru nke obere mfu na njikwa dị mfe, a pụkwara iwere ya dị ka CPU nke nnyefe ozugbo dị nro. Ugbu a, IGBT etinyere na ọrụ ahụ bụ ngwaahịa niile ebubatara, ọkachasị ABB na Siemens, ebe IGBT nke dị n'ime ụlọ nwere nnukwu voltaji na ikike dị elu enweghị ngwaahịa tozuru oke. Ugbu a, ọganihu mpaghara na-aga nwayọ, ntụkwasị obi mbubata siri ike, ihe egwu dịkwa oke. N'otu oge ahụ, ọnụ ahịa IGBT bụ ihe dị ka 30% nke ọnụ ahịa valvụ.

Ohere nke IGCT ọhụrụ: N'ihi obere ohere nke IGBT na China, anyị na-agbalị iji IGCT dochie IGBT. Ugboro mgbanwe, ike ịnya ụgbọala na arụmọrụ ndị ọzọ nke IGCT ọdịnala dị ala karịa IGBT, mana o nwere ụfọdụ uru na ikike, mfu steeti, mfu mgbanwe na ọnụ ahịa (ọnụ ahịa ngwaahịa nwere otu ikike ahụ bụ ihe dị ka 1/2 nke IGBT). Agbanyeghị, ọ bụrụ na etinyere IGCT ọdịnala na nnyefe ike mgbanwe UHV, ozugbo agbanyere IGCT, diode ahụ ga-emepụta nnukwu ọkụ mgbake azụ, nke ga-enwe nnukwu mmetụta na sistemụ ahụ. Ya mere, iji chebe diode ahụ, anyị nyochachara ICCT ọhụrụ site na ịgbakwunye sekit nnabata ọzọ na modulu IGCT ọdịnala iji belata mmetụta na sistemụ ahụ.

Ngwa IGCT Ọhụrụ: Site na mgbakwunye nke sekit nnabata ndị ọzọ, imewe IGCT ọhụrụ anyị dị obere ma nwee ike iguzogide mmetụta dị elu na ntụkwasị obi dị elu, yabụ anyị nwere ike imepụta ihe mkpuchi nwere ntụkwasị obi mkpuchi dị elu na ike igwe. Xd Power System Co., Ltd. na-eme nnyocha tupu oge eruo maka ihe mkpuchi maka sekit nnabata IGCT maka ọrụ Yunnan Maitrei. Ọ bụrụ na imewe ahụ dabere na atụmatụ sistemụ XD Power, ọnụọgụ modulu IGCT ga-ebelata ihe dị ka 3% ma e jiri ya tụnyere IGBT, mkpokọta ihe mkpuchi ga-abụ ugboro 2-3 nke IGBT.
