Abstract
A sensor is configured to sense the rate of change of a current in order to protect the bridge arms in a power module with power layers and measurement layers. The sensor includes at least three conductors (C, C, Cp) and coils. One end of each conductor is connected to a common node, while the other end of each conductor is used respectively as an electrical terminal. The at least three conductors are contained in the same plane, referred to as the primary plane, while each conductor has a plane of symmetry perpendicular to the primary plane, each plane of symmetry passing through the common node and the corresponding terminal. A first conductor and a second conductor are identical and positioned symmetrically relative to a third conductor, and at least one pair of coils is positioned symmetrically relative to a plane of symmetry.
