Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an electric power steering device capable of reducing generation of noise caused by changing magnetostriction sound to noise, and a control device of the electric power steering device.SOLUTION: A voltage V(Thys) corresponding to a PWM pulse for materializing a time Thys for hysteresis is added to the voltage command value of a voltage maximum phase among three phase first voltage command values, and a voltage V(Thys) is subtracted from the voltage command value of a voltage minimum phase to find a virtual voltage command value, and the virtual voltage command values are compared to determine the maximum, intermedium, and minimum phases of the voltage.
