    摘要： An assembly including an insulated gate bipolar transistor (IGBT) is provided. The IGBT is coupled with a gate driver for receiving a gating signal to drive the IGBT and providing a feedback signal of the IGBT which indicates a change of a collector-emitter voltage of the IGBT. The assembly further includes a failure mode detection unit for determining whether the IGBT is faulted based on a timing sequence of the gating signal and feedback signal. The failure mode detection unit is capable of differentiating fault types including a gate driver fault, a failed turn-on fault, a short-circuit fault, a turn-on over-voltage fault and a turn-off over-voltage fault. Accordingly, an IGBT failure mode detection method is also provided.

    摘要： A solid state circuit breaker, including a solid state switch, an inductor connected with the solid state switch in series and a fault detection circuit. The solid state switch has a gate electrode, a source electrode and a drain electrode. The fault detection circuit is used for detecting health status of the solid state switch and identifying fault type of the solid state switch in a condition that a fault occurs on the solid state switch based on one or more of a measured voltage between the source electrode and the drain electrode of the solid state switch, a measured voltage of two terminals of the inductor, a reference voltage and a switching control signal provided to the gate electrode of the solid state switch. A motor driving system having the solid state circuit breaker is further disclosed.

    摘要： A protection system includes a control module, a switch, and an inductive device. The control module is used to provide control signals and switching signals based at least in part on a detected signal measured by a detecting device. The control signals include a first control signal corresponding to a normal mode and a second control signal corresponding to a fault mode. The switch is switched on and off according to the switching signals. The inductive device is coupled with the switch. The inductive device is controlled to be operated with a first inductance in response to the first control signal provided from the control module and a second inductance in response to the second control signal provided from the control module.
