Abstract
In a switching power-supply apparatus that controls magnitudes of output voltages of respective converters connected in parallel to be equal to a target voltage value, only a selected one of the converters is made to operate. In this state, correction values generated by the respective converters are received and stored in memory. Droop characteristics generated for the respective converters are corrected using the correction values. Accordingly, a switching power-supply apparatus and a droop characteristic correction method capable of correcting variations in droop characteristics generated for respective power converters are provided.
