CONDITIONING SYSTEM FOR A TRIBOELECTRIC NANOGENERATOR OR AN ELECTROSTATIC KINETIC ENERGY HARVESTERSYSTEM FOR A TRIBOELECTRIC NANOGENERATOR OR AN ELECTROSTATIC KINETIC ENERGY HARVESTER

摘要

The present invention concerns a conditioning system for a triboelectric energy generator or an electrostatic kinetic energy harvester, with a first stage comprising: an AC-to-DC voltage rectifier (1), intended to be connected to the energy harvesting device (E); an input capacitor (2) C_input, connected to the output of the AC-to-DC voltage rectifier; with an input voltage across C_input between a high voltage terminal (N, N1, N2) and a ground terminal, a second stage comprising: a self-actuated electromechanical switch with electrostatic actuation having at least one mobile electrode (3), the self-actuated electromechanical switch (3) having an actuation voltage driven by the high-voltage terminal (N, N1, N2) of the input capacitor (2) C_input and the converter input terminal (O), the self actuated electromechanical switch (3) having a first electrode (6) being connected to the high-voltage terminal (N, N1, N2) of the input capacitor (2) C_input, and a second electrode (7) being connected to the converter input terminal O, a step-down DC-DC converter (4, 5), with a converter input terminal (O) and a converter output terminal (P); the self-actuated electromechanical switch creating an hysteresis of the actuation voltage by realizing: a current at the ambient gas breakdown voltage between the two electrodes (6, 7) when the input voltage corresponds to a ON actuation voltage V_ON equals to the ambient gas breakdown voltage.
