Reactive Snubber For Inductive Load Clamp Diodes
US Patent:
4392172, Jul 5, 1983
Filed:
Oct 19, 1981
Appl. No.:
6/312526
Inventors:
James W. B. Foley - Peru MA

International Classification:

Abstract:
A saturable reactor snubber to improve the recovery characteristics of a clamp diode used in a power switching circuit is provided with a secondary winding to permit saturating the reactor via a secondary current pulse in order to improve the turn-on speed of the clamp diode. The current pulse for saturating the reactor at turn-on is preferably derived from a shunt snubber charging pulse or from an external generator synchronized to the turn-off time of a power switching device in the switching circuit.
