Mene ne IGBT-transistor?

A layi daya tare da nazarin da kaddarorin semiconductors da kuma kyautata faru na'urar ƙiren ƙarya fasahar daga gare ta. A hankali, kamar yadda more kuma mafi abubuwa, da kyau yi. A farko IGBT-transistor bayyana a shekarar 1985, da kuma hadawa da musamman Properties na bipolar da kuma filin Tsarin. Kamar yadda ya juya waje, wadannan biyu sanannun a wancan lokacin, kamar semiconductor na'urorin iya quite "samun tare" da. Sun kuma kafa wani gini da cewa ya zama wani m da hankali tsiwirwirinsu m shahararsa tsakanin developers na lantarki. The sosai acronym IGBT (makaran Gate Bipolar transistors) yayi Magana game da samar da wani matasan haihuwarka dangane bipolar da kuma filin-sakamako transistors. Kamar wancan ne da ikon rike manyan igiyoyin a cikin ikon haihuwarka na wani hada tsarin da high shigar impedance wani.

Modern IGBT-transistor ne daban-daban daga da wanda ya riga. Gaskiyar cewa fasahar da su samar ma sannu a hankali inganta. Tun da farko rabi da irin wannan tsarin ta asali sigogi sun canja ga mafi alhẽri:

• Sauya sheka irin ƙarfin lantarki ya karu daga 1000V zuwa 4500V. Yana yiwuwa a yi amfani da ikon kayayyaki a lõkacin da aiki a high ƙarfin lantarki haihuwarka. Mai hankali abubuwa da kayayyaki ne mafi m in aiki tare da inductance a cikin ikon kewaye da more amintacce da tãshin hankali amo.
• Sauya sheka halin yanzu ga mai hankali abubuwa karu zuwa 600A cikin wani mai hankali da kuma har zuwa 1800A a wani daidaitaccen sassa zane. Wannan yarda da sauya sheka haihuwarka na babban iko da kuma yin amfani da IGBT-transistor aiki tare da injuna, heaters, daban-daban shigarwa ga masana'antu amfani, da dai sauransu
• Forward ƙarfin lantarki drop a bude jihar ya ragu zuwa 1V. Wannan rage zafin rana kwatami yankin da kuma a lokaci guda na rage hadarin gazawar daga thermal fashewa.
• The sharuddan sauyawa mita a zamani na'urorin kai 75 Hz, wanda damar su yi amfani da a m drive iko haihuwarka. A musamman, da suka yi nasarar amfani da mita converters. Irin wannan na'urorin suna sanye take da PWM kula, wanda aiki a cikin "bond" tare da module, a cikinsa babban kashi - IGBT-transistor. Frequency converters aka hankali ya maye gurbin gargajiya lantarki iko kewaye.
• A yi na na'urar da aka ma ƙwarai karu. Modern IGBT transistors da di / dt = 200mks. Wannan yana nufin lokaci dauka don kunna / kashe. Idan aka kwatanta da na farko samfurori da gudu ya karu fivefold. Kara wannan siga rinjayar yiwu switched mita, wanda yana da muhimmanci a lõkacin da aiki tare da na'urori da aiwatar da manufa na PWM iko.

Har ila yau inganta da kuma lantarki, wadda iko IGBT-transistor. Babban bukatun da shafi su - wannan shi ne don tabbatar da lafiya da kuma abin dogara sharuddan sauyawa na'urar. Su ya kamata ya yi la'akari da duk rauni gefe na transistor, musamman, ya "tsoron" da kuma karuwa rikicewar lantarki.
