Abstract
When an electrical primary frequency of power fluctuation of a motor is smaller than a determination threshold value fththat is a lower limit frequency of a frequency band where resonance occurs in a circuit including a reactor and a capacitor of a boosting converter or greater than a determination threshold value that is an upper limit frequency of the frequency band where resonance occurs, a value Gis set as a gain G and when the electrical primary frequency is equal to or greater than the determination threshold value fthand equal to or smaller than the determination threshold value, a value Gat which the upper limit frequency of the resonant frequency band has a low frequency than the determination threshold value fthis set as the gain G, and a current control in the boosting converter is executed using the gain G set in this way. The resonance of the circuit including the reactor and the capacitor of the boosting converter can be prevented.
