Communication apparatus and control method thereof

A control method of a communication apparatus which has a power receiving unit configured to be capable of wirelessly receiving power from another apparatus, a charging unit configured to be capable of charging a secondary battery using the power received from the another apparatus, a wireless communication unit configured to be capable of performing wireless communication with the another apparatus, a rectification smoothing unit configured to rectify and smooth the power received from the another apparatus and output the rectified and smoothed power, a suppressing unit configured to suppress a transient voltage fluctuation in an output voltage of the rectification smoothing unit, and a driving unit configured to drive the suppressing unit so that the output voltage of the rectification smoothing unit generated by the power received from the another apparatus does not exceed a first voltage, the method comprising:

• until the output voltage of the rectification smoothing unit reaches a voltage that does not exceed the first voltage, gradually increasing charging current of the charging unit that is intended to charge the secondary battery using the power received from the another apparatus;
• and
• until the output voltage of the rectification smoothing unit falls within a range of a second voltage to a third voltage that are lower than the first voltage, further gradually increasing the charging current of the charging unit.
