Abstract
In order to suppress oscillation and malfunction of a switching element in a power converter, the power converter includes a switching element; and an oscillation suppression circuit having a stub which is electrically connected to a terminal of the switching element. A signal of the oscillation frequency is suppressed based on a length of the stub relative to a wavelength of the oscillation frequency. When an incident wave reflects from the open end of the stub, the reflected wave is out of phase with the incident wave, and the incident wave and the reflected wave cancel each other.
