Abstract
A power source device has: a storage unit configured to receive a generated power and store as a storage power; a boost unit configured to generate, from a storage power supplied from the storage unit, a boosted power having a higher voltage than a voltage of the storage power, and supply the boosted power to a load; and a voltage detection unit configured to output a boost operation permission signal permitting a boost operation of the boost unit to the boost unit when the storage voltage of the boost unit increases to become a voltage equal to or higher than a minimum operation voltage of the boost unit. The boost unit is configured to start the boost operation by the storage power supplied from the storage unit and operates on the boosted power generated by the boost operation as an operation power source when the boost operation permission signal is output from the voltage detection unit.
