Réalisation d'une alimentation DC 3,3V sans pile avec récupération d'énergie photovoltaïque et stockage sur supercapacités pour l'alimentation d'un capteur sans fil basse consommation
Abstract : This article deals with the sizing, the characterization and operation of a low cost power supply ,3.3 V 200 mA, without battery, intended for the supply of low consumption wireless sensor nodes over very long durations. A SPV1050 circuit recovers the electrical energy from a photovoltaic panel (5x7 cm²), stores it on two supercapacities in series (12.5 F, 5.2 V), then shapes it with an internal LDO to provide the requested voltage. The problem of a too long initial start-up time for the supercapacity circuits initially discharged is solved in an original way thanks to a preload and a control of the start-up.
