On-chip spectral analysis with low power and optimal Control for energy harvesting using piezoelectric devices

2023-06-222023-06-222018-10-22http://hdl.handle.net/20.500.12272/8085This paper presents a low power DC-DC buckboost topology functioning battery-less on the basis of a novel technique using a combination of both: singular optimal control plus an analog circuit control law. The very low power consumptions along with the optimal energy harvested, makes possible to perform FFT calculations on-line and on-chip for vibration analysis applied to wind-turbines maintenance operation using an ST microcontroller and transmitting up to 500 m. The complete functioning circuit is shown along with real measurements.pdfspaopenAccesshttp://creativecommons.org/licenses/by-nc-nd/4.0/Attribution-NonCommercial-NoDerivatives 4.0 InternacionalSpectral analysis, Microcontroler, Optimal control, Low power, Analog Devices.On-chip spectral analysis with low power and optimal Control for energy harvesting using piezoelectric devicesinfo:eu-repo/semantics/articleCreative Commos10.1109
