摘要:
A horological movement provided with a generator and a circuit for regulating the frequency of rotation of this generator, the regulation circuit being arranged to be able to detect the zero crossings of an induced voltage generated in the stator by the rotating rotor and to generate first braking pulses which are triggered after zero crossings and each end before the induced voltage reaches a peak value, preferably before the rectified induced voltage reaches a power supply voltage provided by a power supply capacity. In addition, the regulation circuit is arranged so as to be able to further generate second braking pulses each of which occurs after detection of the end of a charging period of the power supply capacity during which the induced voltage reaches a peak value and each end before the induced voltage crosses zero.
