INTERFACCIA DI RACCOLTA DI ENERGIA A BASSO CONSUMO ED ELEVATA EFFICIENZA, METODO PER OPERARE L'INTERFACCIA DI RACCOLTA DI ENERGIA, E SISTEMA COMPRENDENTE L'INTERFACCIA DI RACCOLTA DI ENERGIA

摘要

An energy-scavenging interface receives an input signal from a transducer and supplies an output signal to a load. A switch is connected between the transducer and a reference node, and a diode is connected between the transducer and the load. A control circuit closes the switch for a time interval to permit energy storage in the transducer. A scale copy of a peak value of stored electric current is obtained. The switch is opened when the time interval elapses and the stored energy exceeds a threshold. The stored energy is then released to supply the load through the diode. The switch remains open as long as the value of current in the output signal exceeds the value of the scaled copy of the peak value.
