Abstract: The invention relates to a power switching device having at least one transistor of the SiC or GaN MOSFET type able to be traveled by a main current. The power switching device has at least one measuring module configured to indirectly measure the main current of the transistor from the electromagnetic field produced by the transistor and at least one protection circuit configured to detect a short-circuit based on the sign of the temporal drift of the main current.

Abstract: This electrical switching apparatus has at least two power components each including first and second power transistors. A driver control device of the transistors is configured to deliver a first control signal to each of the first transistors and a second control signal to each of the second transistors, and an electrical interconnect device connecting the driver control device to the power components. The interconnect device includes several electrically conductive plates extending parallel to one another, each being connected between a control electrode of one of the first or second power transistors and a corresponding output of the driver control device.
