Abstract
A circuit arrangement for the fast dissipation of the stored magnetic energy in an inductive load (4) controlled by a first switch (T1), comprising a high voltage-drop energy dissipation path (D2) disposed across the first switch (T1) and a second switch (T2) by which a constant-voltage diode drop path (D1) across the load (L1) can be selectively opened.
