Abstract:
Electricity generated by a vibration power generator 200 can be extracted efficiently by providing the vibration power generator 200, a rectifier circuit bridge 205, an output controlling circuit 201, a load detecting circuit 202 and a frequency detecting circuit 204 and detecting a frequency of the vibration power generator 200 and then controlling an impedance of an output controlling circuit 101 depending on the frequency.
