PIEZOELECTRIC POWER GENERATION MODULE AND REMOTE CONTROLLER

摘要

A rectifier circuit (3) rectifies power generation voltage Vpe of a piezoelectric element (1) to generate DC voltage (Vrc) and supplies the power generation voltage Vpe to a load (7). Upon termination of a process started upon reception of the DC voltage (Vrc) supplied from the rectifier circuit (3), the load (7) sets a discharge switch (2) to a conduction state using an output port signal (Sp). The electric charge remaining in the piezoelectric element is reset to zero by the discharge switch.
