Insulated-gate bipolar transistor, voltage-driven power transistor with fast switching times

IGBTs have fast switching times, and are not spec'd for operation in an analog region. For these reasons, they are typically used in switching applications, such as switched-mode power supplies and PWM motor drives. They switch slower than FETs, and thus have higher switching losses. But IGBTs are available in higher voltage ranges than FETs, making them the only solution for many applications.
