Abstract The method according to the invention transfers the energy captured by a transducer to a capacitor situated at the output thereof. When the voltage of the capacitor exceeds a certain threshold (WTH), a switched converter, situated between the transducer and the load which it is intended to supply, is activated and transfers the electrical charge from the capacitor to the output load until the voltage of the capacitor falls below another threshold (VTL), at which moment the converter is deactivated and the process is repeated. During the idle time of the converter, a value is obtained that is proportional to the difference in the power values of the transducer, corresponding to two different values of the output voltage thereof. This difference is calculated based on the measurement of the capacitor charging times and the transducer can be placed at the maximum power point thereof by minimising said difference. Método y circuito para la búsqueda y seguimiento del punto de máxima potencia de transductores de energía.Método y circuito para la búsqueda y seguimiento del punto de máxima potencia (MPPT) de transductores o captadores de energía.El método propuesto transfiere la energía captada por un transductor a un condensador situado a su salida. Cuando la tensión del condensador excede un cierto umbral (VTH), un convertidor conmutado situado entre el transductor y la carga que se pretende alimentar, se activa y transfiere la carga eléctrica del condensador a la carga de salida, hasta que la tensión del condensador baja por debajo de otro umbral (VTL), momento en el cual el convertidor se desactiva y el proceso se vuelve a repetir. Durante los tiempos de inactividad del convertidor se obtiene un valor proporcional a la diferencia de potencias del transductor correspondientes a dos valores diferentes de su tensión de salida. El cálculo de dicha diferencia se basa en la medida de tiempos de carga del condensador. Minimizando la diferencia se sitúa al transductor en su punto de máxima potencia.
