Abstract:
An output power controller comprising:an output power determiner that determines a determined output power value depending on an input power value; a power adjuster that adjusts the output power value to the determined output power value by controlling an input current value, wherein the output power determiner determines, as the determined output value, a first determined output power value that shows the input current value as a first value and a second determined output power value that shows the input current value as a second value smaller than the first value; a first timer that measures passage of a first time; a second timer that measures passage of a second time after the first timer measures the first time; and an output power switch that instructs the first value to the output power determiner while the first timer measures passage of the first time, and instructs the second value to the output power determiner while the second timer measures passage of the second time.
