ABSTRACT:
A noise-cut filter device for a power converter, including at least one noise-cut filter, for filtering switching noise occurring upon a switching operation of a semiconductor switching device of the power converter is disclosed. In this filter device, the noise-cut filter includes first and second planar conductors, and a dielectric sheet having upper and lower surfaces on which the first and second conductors are disposed to face each other through the dielectric sheet. The first and second planar conductors cooperate with the dielectric sheet to form a circuit having both functions of an inductor and a condenser. The current of a main circuit of the power converter flows through the opposite ends of the first planar conductor, while the current based on the switching noise, which flows from the first conductor to the second conductor, is led to ground by the second conductor.
