Mupi wePasirose weDziviriro Yezvakatipoteredza

Tekinoroji itsva yakapfava yakatwasuka uye mashandisirwo ayo muzvinhu zvinodzivirira kupisa

Kubva muna 1966, EM Technology yakazvipira kutsvagisa nekugadzira zvinhu zvinodzivirira kupisa. Mumakore makumi mashanu nematanhatu ekurima muindasitiri iyi, hurongwa hukuru hwekutsvagisa hwesainzi hwakagadzirwa, marudzi anopfuura makumi matatu ezvinhu zvitsva zvinodzivirira kupisa kupisa akagadzirwa, zvichipa simba remagetsi, michina, peturu, makemikari, zvemagetsi, mota, kuvaka, simba idzva nedzimwe indasitiri. Pakati pavo, kushandiswazvekudzivirira muchina wekuumba ndeimwe yenzira dzatinonyanya kutarisa.

Sechizvarwa chitsva chetekinoroji yekutumira yeDC, kutumira kweDC kunochinjika kwakafanana nekutumira kweHVDC muchimiro, uko kuchiri kuumbwa nezviteshi zvekushandura uye mitsetse yekutumira yeDC. Kusiyana nekutumira kweHVDC kwerudzi rwechinoshandura chepakutanga chakavakirwa patekinoroji yekuchinja inodzorwa nechikamu, chinoshandura mukutumira kweDC kunochinjika ivoltage source converter (VSC), iyo inozivikanwa nekushandiswa kwemidziyo inochinjika (kazhinji IGBT) uye tekinoroji yemodulation yehigh-frequency. Mumakore achangopfuura, kutumira kweDC kunochinjika kuri kukura kusvika padanho repamusoro uye kugona.

Mamiriro ekushandiswa kweIGBT: IGBT yakazara nechubhu yebipolar gate insulated, inogona kudzimwa, ine mabhenefiti ekurasikirwa kudiki uye nyore kudzora, uye inogona kuonekwa seCPU yekutumira zvakananga. Parizvino, IGBT inoshandiswa papurojekiti iyi zvese zvigadzirwa zvinotengeswa kunze kwenyika, kunyanya ABB neSiemens, nepo IGBT yemuno ine voltage yakakwira uye kugona kwayo haina zvigadzirwa zvakakura. Parizvino, kufambira mberi kwenzvimbo kuri kunonoka, kuvimba nekutumira kunze kwakasimba, uye njodzi yakakura. Panguva imwe chete, mutengo weIGBT unoita 30% yemari yevharuvhu.

Kugona kweIGCT itsva: Tichifunga nezvekusagona kweIGBT muChina, tinoedza kutsiva IGBT neIGCT. Kuchinja-chinja kwemajini, simba rekutyaira uye mamwe mashandiro eIGCT yechinyakare hazvina kunaka pane IGBT, asi zvine zvakanakira pakugona, kurasikirwa padanho, kurasikirwa nekuchinjana uye mutengo (mutengo wezvigadzirwa zvine kugona kwakafanana ungangoita 1/2 yeIGBT). Zvisinei, kana IGCT yechinyakare ikashandiswa kuUHV flexible power transmission, kana IGCT yavhurwa, diode ichagadzira reverse recovery current hombe, iyo ichava nemhedzisiro huru pasystem. Saka, kuti tidzivirire diode, takaongorora ICCT itsva nekuwedzera mamwe ma absorption circuits pamodule yeIGCT yechinyakare kuti tideredze kukanganisa pasystem.

Mashandisirwo Matsva eIGCT: Nekuwedzera mamwe macircuit ekunyudza, dhizaini yedu itsva yeIGCT iri diki uye ine simba rekudzivirira kupisa uye yakavimbika zvakanyanya, saka tinogona kugadzira zvinhu zvekunyudza zvine simba rekudzivirira kupisa uye simba remakanika. Xd Power System Co., Ltd. iri kutsvaga zvinhu zvekunyudza kupisa zveIGCT absorption circuit yeYunnan Maitrei project. Kana dhizaini yacho yakavakirwa pachirongwa cheXD Power system, huwandu hwemamodule eIGCT huchaderedzwa neinenge 3% zvichienzaniswa neIGBT, uye huwandu hwese hwezvinhu zvekunyudza huchave hwakapetwa kaviri kusvika katatu kupfuura hweIGBT.
