Streufeldarme stromkompensierte RingkerndrosselLow-leakage current-compensated toroidal core choke

if Es sind stromkompensierte Ringkerndrosseln bekannt. Da beim Betrieb dieser Drosseln die Magnetfelder der beiden Wicklungen gegeneinander gerichtet sind (stromkompensiert), entsteht ein Streufeld, das andere Teile der Schaltung f negativ beeinflussen kann. Andererseits ist es wünschenswert, zur Dämpfung f der symmetrischen Störkomponente die Streuinduktivität groß ai halten. if Current-compensated toroidal chokes are known. Since the magnetic fields of the two windings are directed against one another (current-compensated) when these chokes are in operation, a stray field arises which can negatively affect other parts of the circuit f. On the other hand, it is desirable to keep the leakage inductance ai high in order to dampen f the symmetrical interference component.

I Neuerungsgemäß wird dieser Mangel dadurch behoben, daß um die fertig ge-I According to the innovation, this deficiency is remedied by the fact that
