PURPOSE: A converter for an electric vehicle is provided to remove a ripple voltage including a notch filter part in the output stage of a buck converter, thereby outputting a stable voltage. CONSTITUTION: A converter for an electric vehicle includes a voltage input part(210), a switching part(215), a rectifying/smoothing part(220), and a notch filter part(230). The voltage input part is input with a first direct current voltage supplied to a system. The switching part converts the first direct current voltage into an alternating current voltage. The rectifying/smoothing part rectifies the alternating current voltage, and then outputs a second direct current voltage. The notch filter removes a certain frequency from the second direct current voltage, and then outputs a third direct current voltage. The ripple voltage of the third direct current voltage is smaller than the ripple voltage of the second direct current voltage. |
