Abstract: The present invention concerns the domain of inductive contactless sensors, allowing the position and/or the movement of a target sensitive to a magnetic field to be detected. The invention provides a miniature sensor comprising at least a primary coil generating an alternating magnetic field and at least two secondary coils for picked up such field, the coils being planar. The amplitude of the signal picked up by each coil is when the target passes in front of the coils, so that by measuring the signal amplitude or phase modulation, the speed and the direction of movement, or position of the object to be detected, is detected.

Abstract: A power semiconductor circuit comprises a gate-turn-off semiconductor component (FCTh1, FCTh2) having an anode, a cathode and a gate, a diode (D1, D2) and a drive circuit which is connected to the gate by a large-area, low-inductance stripline (11) and which generates a current pulse for turning off the semiconductor component. The diode (D1, D2) is arranged in series with the semiconductor component (FCTh1, FCTh2), specifically in such a way that the diode (D1, D2) and semiconductor component (FCTh1, FCTh2) form a quarter-bridge arm. Provided in parallel with the series circuit of the semiconductor component (FCTh1, FCTh2) and diode (D1, D2) is a low-inductance blocking capacitor (C1, C2) for absorbing the reverse recovery voltage peaks of the diode (D1, D2). The diode (D1, D2) and blocking capacitor (C1, C2) are arranged with low inductance and spatially immediately adjacent to the semiconductor component.
