Abstract
An alternating current (AC) power device includes an AC circuit having input nodes, output nodes and a ground node. The AC circuit is configured to receive an input electrical signal at the input nodes and generate an output electrical signal at the output nodes. The AC power device also includes an inductor coupled to the ground node of the AC circuit. The ground node is configured to be coupled to a ground plane at a ground potential. The AC circuit is configured to be coupled to a load at the output nodes. The inductor is configured to be connected in series between the ground node of the AC circuit and the load to attenuate radio frequency components present at the ground node.
