Title: POWER SUPPLY DEVICE
Abstract:
The present invention is a power supply device for outputting generated power from a power generation unit via a control unit to an object to which power is to be supplied, wherein: the power generation unit includes a plurality of DC power generation units each composed of a combination of at least a vibration power generation element for performing vibration power generation due to external vibration from outside the power supply device and a rectifying circuit for rectifying the output of the vibration power generation element; the plurality of DC power generation units are connected in parallel to the control unit; and in the individual DC power generation units, unit output powers that have passed through the rectifying circuit are input in parallel to the control unit. In this manner, the efficiency of vibration power generation due to external vibration is enhanced, and the amount of power to the object to which power is to be supplied is increased as much as possible.
