摘要: A control device for an electric vehicle having a reverse L type first filter circuit composed of a first filter reactor and a first filter capacitor between a current collector and control means for controlling electric motor of the electric vehicle. A second filter circuit composed of a series connected second filter reactor and a second filter capacitor is connected in parallel to the first filter capacitor. The second filter circuit has circuit constants selected such that a composite impedance of the second filter circuit and the first filter capacitor when viewed from the control means becomes small at a specific frequency.
