Reliability of IGCT based drives
Reliability and availability

Reliability – Part 4

Reliability and availability (Part 4: IGCT based converters) IGCT is a power semiconductor used in medium voltage converter applications. The abbreviation stands for Integrated gate-commutated thyristor. Unlike classical thyristor that can only be switched on, IGCT can be switched on and off through its adjacent gate unit. Therefore, it is Read more…
