Abstract

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