Abstract:
An electronic circuit for regulating the speed of rotation of a microgenerator, comprising: a first input and a second input for connection to said microgenerator, an oscillator supplying a reference signal of a predetermined frequency, an energy-dissipation circuit for braking said microgenerator, energy-dissipation control means for controlling the energy dissipation of the energy-dissipation circuit as a function of the reference signal and of the signal between said inputs, a rectifier and voltage-transformer circuit for rectifying and multiplying the signal between said first and second inputs, the rectifier and voltage-transformer circuit comprising at least one capacitor which can be charred by said microgenerator via at least one switch, and at least one control circuit of said switch or switches,wherein said control circuit comprises at least one storage means which in a first phase with blocked switch stores at least one control signal to be applied to said switches, said switches being triggered in a second phase by means of said control signal, and wherein said control circuit comprises a comparator, said comparator being used for generating said control signal applied to said control means.
