Abstract

See full text

The invention concerns a circuit for recuperating electrical energy from a mechanical resonator (402) comprising: a voltage inversion circuit (408) configured to invert the voltage across a capacitance (Cp) of the mechanical resonator, the voltage inversion circuit comprising: a capacitor (Cint); and a charge transfer circuit configured: to discharge a voltage of a first polarity held by the capacitance of the mechanical resonator to said capacitor during a first period; and to charge a voltage, of opposite polarity to the first polarity, to the capacitance of the mechanical resonator during a second period using the voltage potential stored by said capacitor during the first period; wherein the charge transfer circuit comprises an inductance and at least one switch controllable to limit the current passing through the inductance.
