Single-turn chokes employing a number of nanocrystalline cores assembled in a stack are an effective solution for bearing current
problems or extremely high common mode noise from other causes inlarge-scale variable speed drives, wind generators and other
applications in which resonance phenomena cause high-amplitude interference currents (with peak values ranging from several
10 A to over 100 A). These generally take the form of short and thus high-frequency current peaks. For these applications.
