Wireless communication apparatus and power-supply apparatus |
摘要 |
A wireless communication apparatus includes a power-supply apparatus configured to supply electric power to a load that is intermittently operated by using a battery as a power supply; and a control unit configured to control the power-supply apparatus, wherein the power-supply apparatus includes a capacitor; a switching unit capable of selectively forming a first path through which charging is performed from the battery to the capacitor and a second path through which the battery is connected in series with the capacitor, and wherein the control unit controls the switching unit so that the first path is formed during a period in which the load is idle and the second path is formed during a period in which the load is not idle, and thereby supplies the voltage of the sum of the battery voltage and the charged voltage of the capacitor in a non-idle period. |
