IGBT characterisation for their protection by fuses

The case of a power IGBT can be severely damaged by high fault currents. Fast fuses can eliminate this problem. Studies and tests show that a specially designed fuse can prevent an IGBT from exploding and keep the circuit inductance below acceptable values. A thermal model is proposed in order to se...

Description
Summary:The case of a power IGBT can be severely damaged by high fault currents. Fast fuses can eliminate this problem. Studies and tests show that a specially designed fuse can prevent an IGBT from exploding and keep the circuit inductance below acceptable values. A thermal model is proposed in order to see how an IGBT behaves thermally during short circuits and thus to select the appropriate fuse.< >
