dc.descriptionEste artigo presenta un estudo analítico sobre a tensión residual que queda no condensador piezoeléctrico despois de cada ciclo nos métodos de Extracción de Carga Eléctrica Síncrona (SECE) sen indutor. Derívase unha expresión en forma pechada para esta tensión e examínase o seu impacto na eficiencia da recollida de enerxía. As ecuacións resultantes valídanse mediante métodos numéricos e simulacións en Spectre. A análise subliña as principais limitacións de deseño, como a resistencia do conversor DC-DC, que restrinxe a extracción de enerxía nos recoletores totalmente integrados baseados en SECE.
dc.description.abstractThis article presents an analytical study of the residual voltage left in the piezoelectric capacitor after each cycle in inductor-less Synchronous Electric Charge Extraction (SECE) methods. A closed-form expression for this voltage is derived, and its impact on the energy harvesting efficiency is examined. The resulting equations are validated using numerical methods and spectre simulations. The analysis highlights key designs constraints, such as the DC-DC converter’s resistance, that limit energy extraction in fully integrated SECE-based harvesters.
