Abstract
An electric coupler includes a body, a first electrical path through the body having a first resistance to electric current within a first frequency range and a second electrical path through the body having a second resistance to electric current within a second frequency range.
Claims20
An electric coupler comprising:
- a first body and a second body, each body comprising,
- at least one inner layer and at least two outer layers, each layer being configured to receive a current;
- wherein, the at least one inner layer is electrically connected on one side to a first outer layer of the at least two outer layers, and is electrically connected on an opposite side to a second outer layer of the at least two outer layers, each connection defining an interface between the inner layer and the first and second outer layers;
- and
- wherein, the first body and the second body are connected via an insulator;
- a first electrical path provided through a first material of the inner layer of the first body and the second body having a first resistance to an electric current within a first frequency range;
- and
- a second electrical path provided through a second material of the first and second outer layers of the first body and the second body having a second resistance to an electric current within a second frequency range.

A power converter, comprising:
- an input stage configured to receive alternating or direct current;
- an output stage configured to output alternating or direct current;
- a voltage stabilizing capacitor between the input stage and the output stage, and a coupler, the coupler including, a first body;
- wherein, the first body comprises at least one inner layer and at least two outer layers, each layer being configured to receive a current;
- a first electrical path provided through a first material of the inner layer of the first body having a first resistance to an electric current within a first frequency range;
- and
- a second electrical path provided through a second material of the first and second outer layers of the first body having a second resistance to an electric current within a second frequency range.

A method of conducting electrical current through a bus bar of a power converter, the method comprising:
- providing an electric coupler in series with the bus bar;
- wherein, the coupler includes a first body and a second body, each body having at least one inner layer and at least two outer layers, each layer being configured to receive a current;
- conducting an electric current within a first frequency range through a first layer of the bus bar at a first resistance;
- and
- conducting an electric current within a second frequency range through at least one of a second layer and a third layer of the bus bar at a second resistance.
