Abstract
An improved inductor for a DC link that has an auxiliary winding for inducing an opposing magnetic field in a magnetically permeable core with an auxiliary DC current that opposes a magnetic field that a primary winding for the inductor induces along a magnetic path in the core with a DC component of current to reduce magnetic saturation of the inductor due to the DC component.
