Insulated-gate bipolar transistors (IGBTs) are three-terminal power semiconductor devices primarily used as electronic switches that combine high efficiency and fast switching. As modules, IGBTs are configured as asymmetrical bridges, boost, buck and brake choppers, full-bridge, three-level and three-phase inverters. Some have built-in NTC thermistors for temperature monitoring. IGBT modules are differentiated by max power, collector current, collector-emitter breakdown voltage and configuration.
