Abstract
Official abstract text for this publication.
A power supply apparatus includes a power supply unit that outputs first power used for wireless communication or second power used for wireless power supply, a communication unit that performs a wireless communication by modulating the first power output from the power supply unit, and a control unit that controls the second power output from the power supply unit in a manner that a predetermined condition corresponding to a test mode is satisfied, in a case where the power supply apparatus is in the test mode.
First claim
Opening claim text (preview).
What is claimed is: 1 . A power supply apparatus comprising: a power supply unit that outputs first power used for wireless communication or second power used for wireless power supply; a communication unit that performs a wireless communication by modulating the first power output from the power supply unit; and a control unit that controls the second power output from the power supply unit in a manner that a predetermined condition corresponding to a test mode is satisfied, in a case where the power supply apparatus is in the test mode. 2 . The power supply apparatus according to claim 1 , wherein, in a case where the power supply apparatus is in the test mode, the control unit controls the communication unit in a manner that the first power is modulated in accordance with a corresponding communication standard of the communication unit when the first power is output from the power supply unit. 3 . The power supply apparatus according to claim 1 , wherein, in a case where the power supply apparatus is in the test mode, the control unit controls the communication unit in a manner that the first power is modulated in accordance with a bit rate corresponding to a corresponding communication standard of the communication unit when the first power is output from the power supply unit. 4 . The power supply apparatus according to claim 1 , wherein the control unit can set the second power in accordance with a maximum value of power that can be output by the power supply unit, and wherein, in a case where the power supply apparatus is in the test mode, the power supply unit outputs the second power set by the control unit. 5 . The power supply apparatus according to claim 1 , wherein, in a case where the power supply apparatus is in the test mode, the control unit controls the power supply unit in a manner that, after a first time elapses since the modulation of the first power is ended, power output from the power supply unit is changed from the first power to the second power. 6 . The power supply apparatus according to claim 1 , wherein, in a case where the power supply apparatus is in the test mode and a case where power output from the power supply unit is changed from the first power to the second power, the control unit controls the power supply unit in a manner that a time when a carrier voltage of power output from the power supply unit is changed from a first voltage to a second voltage that is higher than the first voltage is within a second time. 7 . The power supply apparatus according to claim 6 , wherein, in a case where the power supply apparatus is in the test mode and a case where power output from the power supply unit is changed from the second power to the first power, the control unit controls the power supply unit in a manner that a time when the carrier voltage of power output from the power supply unit is changed from the second voltage to the first voltage is within a third time. 8 . The power supply apparatus according to claim 6 , wherein, in a case where the power supply apparatus is in the test mode and a case where power output from the power supply unit is changed from the first power to the second power, the control unit controls the power supply unit in a manner that, after the carrier voltage of power output from the power supply unit is changed to a voltage lower than the first voltage, the carrier voltage of power output from the power supply unit is changed to the second voltage. 9 . The power supply apparatus according to claim 6 , wherein, in a case where the power supply apparatus is in the test mode and a case where power output from the power supply unit is changed from the first power to the second power, the control unit controls the power supply unit in a manner that, after the output of power via the power supply unit is stopped, the carrier voltage of power output from the power supply unit is changed to the second voltage. 10 . The power supply apparatus according to claim 6 , wherein, in a case where the power supply apparatus is in the test mode and a case where power output from the power supply unit is changed from the second power to the first power, the control unit controls the power supply unit in a manner that, after the carrier voltage of power output from the power supply unit is changed to a voltage lower than a communication voltage that is lower than the first voltage, the carrier voltage of power output from the power supply unit is changed to the communication voltage. 11 . The power supply apparatus according to claim 6 , wherein, in a case where the power supply apparatus is in the test mode and a case where power output from the power supply unit is changed from the second power to the first power, the control unit controls the power supply unit in a manner that, after the output of power via the power supply unit is stopped, the carrier voltage of power output from the power supply unit is changed to a communication voltage that is lower than the first voltage. 12 . A method comprising: causing a power supply unit to output first power used for wireless communication or second power used for wireless power supply; performing a wireless communication by modulating the first power output from the power supply unit; and controlling the second power output from the power supply unit in a manner that a predetermined condition corresponding to a test mode is satisfied, in a case where the power supply apparatus is in the test mode. 13 . A non-transitory storage medium that stores a program for causing a computer to execute a method, the method comprising: causing a power supply unit to output first power used for wireless communication or second power used for wireless power supply; performing a wireless communication by modulating the first power output from the power supply unit; and controlling the second power output from the power supply unit in a manner that a predetermined condition corresponding to a test mode is satisfied, in a case where the power supply apparatus is in the test mode.
