POWER GENERATION UNIT, ELECTRONIC APPARATUS, TRANSPORTATION DEVICE, AND METHOD OF CONTROLLING POWER GENERATION UNIT |
摘要 |
A power generation unit includes a beam (a deforming member) having a piezoelectric element and deforming while switching a deformation direction, an inductor electrically connected to the piezoelectric element, a switch disposed between the piezoelectric element and the inductor, a memory (a storage section) adapted to store switching period information (information of a characteristic vibration period of the beam), and a control circuit (a control section) adapted to control one of a timing at which the switch is set to a conductive state and a timing at which the switch is set to a nonconductive state in accordance with the switching period information stored in the memory.
