Core Engineering Challenge: Kev Sib Tw Siab dv/dt Hloov Cov Teeb Meem
Nyob rau hauv niaj hnub IGBT thiab SiC inverter tsim, lub fwj tseem ceeb tsis yog lub peev xwm tam sim no, tab sis tswj kev hloov pauv ceev ceev hauv cov xwm txheej siab dv / dt. Ib txwm siv cable thaiv lossis tuab tooj liab tuav qhia:
• Cov cheeb tsam loj tam sim no.
• High parasitic stray inductance.
• Qhov hluav taws xob hnyav dhau ntawm tig -tawm.
• Tsis ruaj khov waveforms thiab electromagnetic cuam tshuam (EMI).
Peb Laminated Busbars daws qhov no ntawm cov qauv txheej txheem. Los ntawm muab cov khoom zoo thiab tsis zoo nyob rau hauv nruj, sib npaug ntawm electromagnetic coupling, cov hlau nplaum sib nqus tawm tsam ib leeg tawm.
