Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A power source device, comprising: 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 being configured to start the boost operation by the storage power supplied from the storage unit and operating 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. 2. The power source device according to claim 1 , wherein a power consumption of the voltage detection unit is smaller than a power consumption of the boost unit. 3. The power source device according to claim 1 , further comprising: a second boost unit configured to generate, from the storage power supplied from the storage unit, a second boosted power having a voltage which is higher than the voltage of the storage power and is equal to or higher than the minimum operation voltage of the boost unit, and supply the generated second boosted power as an operation power source of the boost unit. 4. The power source device according to claim 2 , further comprising: a second boost unit configured to generate, from the storage power supplied from the storage unit, a second boosted power having a voltage which is higher than the voltage of the storage power and is equal to or higher than the minimum operation voltage of the boost unit, and supply the generated second boosted power as an operation power source of the boost unit.
