IGBT
Electrical Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A three-terminal semiconductor device combining high input impedance of MOSFETs with low saturation voltage of bipolar transistors. It is widely used in power electronics for switching and amplification.
Example in context
“The inverter's output stage uses IGBT modules to handle high voltage and current with fast switching.”
“Inverterin çıkış aşaması, yüksek voltaj ve akımı hızlı anahtarlama ile yönetmek için IGBT modülleri kullanır.”
Where engineers use it
IGBTs are found in motor drives, power supplies, and traction systems. Engineers select IGBTs for high-power switching applications requiring both high voltage and current capacity.
Synonyms: insulated gate bipolar transistor
Practice: can you use “IGBT” at work?
You are specifying semiconductors for a 100 kW motor drive. Explain why IGBTs are chosen over MOSFETs at this power level.
