Abstract: The invention relates to a static converter connected between an electrical voltage source and an electrical load, said converter including a main static conversion arm comprising an output electronic switching cell and a backup conversion arm having identical structures. The static converter includes a pair of fuses connected on either side of the main arm, and a switching circuit comprising a connection element connecting the backup arm to the connection points between the fuses and the input terminals of the main arm, such that, when a fault occurs on one of the switching cells forming the main arm, a stable conductive link is established between the two fuses, the main arm is isolated by the two fuses, and the backup arm is spontaneously connected to the output of the main arm via the conductive line and replaces the main arm.

Abstract: An optoelectronic device for measuring the water content in a plant element and an apparatus designed to evaluate and monitor in real time the state of hydration of the plant covers. The device includes an optoelectronic probe connected to a measurement module, the probe including: i) a first light source emitting at a wavelength corresponding to a strong water absorption band; ii) optionally, a second light source emitting at a wavelength close to the first source and weakly absorbed by water; and iii) a photo receiver having a spectral response that corresponds to the emission bands of the first light source or of the first and second light sources, the device including elements for modulating the average optical power emitted by the light source or sources at a defined frequency, and elements for synchronously detecting the light received by the photoreceiver.
