Webimportant failure is the failure of one IGBT module. This failure can happen during the current commutation from the load current path to the main breaker. If one position fails the IGBT module goes to short circuit failure mode and the hybrid DC breaker can still interrupt the fault current, but the positions beside it shall survive. WebApr 6, 2024 · IGBT is the short form of Insulated Gate Bipolar Transistor. It is a three-terminal semiconductor switching device that can be used for fast switching with high efficiency in many types of electronic devices. These devices are mostly used in amplifiers for switching/processing complex wave patters with pulse width modulation (PWM).
