Abstract
According to an aspect, an inductor damper circuit includes a shared magnetic core, a primary winding, and a secondary winding. The primary winding includes an inductor winding of a first wire gauge wound about the shared magnetic core. The secondary winding includes a resistive damper winding of a second wire gauge that is less than the first wire gauge and wound about the shared magnetic core in contactless magnetic coupling with the primary winding.
