Abstract
There is provided a power converter which can suppress a surge voltage and reduce noise flowing from an input of a power changer. The power converter includes an inverter circuit, a capacitorfor smoothing DC power, a capacitorfor removing noise, and conductorsand. The conductorsandare connected to the capacitorsandwhen power side terminalsandare connected to an inverter circuit, and power source side terminalsandare connected to a battery. In the conductorsand, a parasitic inductance Lbetween capacitor terminalsandand capacitor terminalsandis larger than a parasitic inductance Lbetween capacitor terminalsandand the power side terminalsand
