A piezoelectric generator including: a piezoelectric element; a circuit for shorting and placing in open circuit the piezoelectric element; and an inductive converter.

Piezoelectric generator

An electronic or electromechanical system including at least one electrical energy source, a first circuit capable of operating in at least two operating modes, one of which corresponds to the stopping of the application circuit, and a circuit for transmitting the electrical energy from the energy source to the application circuit, the transmission circuit being further capable of determining a first value of the maximum instantaneous electric power capable of being supplied by the energy source, of determining a second value of the instantaneous electric power consumed by the application circuit in at least one of the operating modes, and of storing the first and second values or of selecting the operating mode of the application circuit from among said at least two operating modes based on the first and second values.

Electric energy transmission circuit

A circuit for controlling a first field-effect transistor of a power converter, intended for a converter including at least one first and one second transistor connected in series between two terminals for applying a first voltage, the circuit including a circuit for detecting the opening of the second transistor.
